80-485: The 710-metre-long (2,329 ft) bridge, which featured a 270-metre-long (886 ft) suspended section, was intended to resemble San Francisco's Golden Gate Bridge . Construction on the bridge commenced in 1995 and was completed in 2001. It was the longest suspension bridge in Indonesia. On 26 November 2011, the bridge collapsed only ten years after it was completed, killing at least 20 people and injuring 39. The bridge

160-474: A "bridge within a bridge" in the southern abutment, to avoid the need to demolish Fort Point, a pre–Civil War masonry fortification viewed, even then, as worthy of historic preservation. He penned a graceful steel arch spanning the fort and carrying the roadway to the bridge's southern anchorage. Ellis was a Greek scholar and mathematician who at one time was a University of Illinois professor of engineering despite having no engineering degree. He eventually earned

240-494: A 40% lighter, and stronger, steel orthotropic deck panels, over 401 nights without closing the roadway completely to traffic. The roadway was also widened by two feet, resulting in outside curb lane width of 11 feet, instead of 10 feet for the inside lanes. This deck replacement was the bridge's greatest engineering project since it was built and cost over $ 68 million. The bridge-opening celebration in 1937 began on May 27 and lasted for one week. The day before vehicle traffic

320-517: A 55-mile-long (89 km) railroad bridge across the Bering Strait . At the time, Strauss had completed some 400 drawbridges —most of which were inland—and nothing on the scale of the new project. Strauss's initial drawings were for a massive cantilever on each side of the strait, connected by a central suspension segment, which Strauss promised could be built for $ 17 million (equivalent to $ 476 million in 2023). A suspension-bridge design

400-475: A bridge could not be built across the 6,700-foot (2,000-metre) strait, which had strong, swirling tides and currents, with water 372 ft (113 m) deep at the center of the channel, and frequent strong winds. Experts said that ferocious winds and blinding fogs would prevent construction and operation. Although the idea of a bridge spanning the Golden Gate was not new, the proposal that eventually took hold

480-585: A central suspension segment) was unacceptable from a visual standpoint. The final suspension design was conceived and championed by Leon Moisseiff , the engineer of the Manhattan Bridge in New York City. Irving Morrow, a relatively unknown residential architect, designed the overall shape of the bridge towers, the lighting scheme, and Art Deco elements, such as the tower decorations, streetlights, railing, and walkways. The famous International Orange color

560-574: A degree in civil engineering from the University of Illinois prior to designing the Golden Gate Bridge and spent the last twelve years of his career as a professor at Purdue University. He became an expert in structural design, writing the standard textbook of the time. Ellis did much of the technical and theoretical work that built the bridge, but he received none of the credit in his lifetime. In November 1931, Strauss fired Ellis and replaced him with

640-576: A former subordinate, Clifford Paine, ostensibly for wasting too much money sending telegrams back and forth to Moisseiff. Ellis, obsessed with the project and unable to find work elsewhere during the Depression, continued working 70 hours per week on an unpaid basis, eventually turning in ten volumes of hand calculations. With an eye toward self-promotion and posterity, Strauss downplayed the contributions of his collaborators who, despite receiving little recognition or compensation, are largely responsible for

720-693: A land holding company. The last incarnation of the Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system. The Southern Pacific Transportation Company was acquired in 1996 by the Union Pacific Corporation and merged with their Union Pacific Railroad . The Southern Pacific legacy founded hospitals in San Francisco , Tucson , and Houston . In

800-476: A link became feasible. Joseph Strauss served as chief engineer for the project, with Leon Moisseiff , Irving Morrow and Charles Ellis making significant contributions to its design. The bridge opened to the public in 1937 and has undergone various retrofits and other improvement projects in the decades since. The Golden Gate Bridge is described in Frommer's travel guide as "possibly the most beautiful, certainly

880-521: A local whale watching operator. Tolls are only collected from southbound traffic at the toll plaza on the San Francisco side of the bridge. All-electronic tolling has been in effect since 2013, and drivers may either pay using the FasTrak electronic toll collection device, using the license plate tolling program, or via a one time payment online.

960-445: A metal curb, but railings between the walkways and the traffic lanes were added in 2003, primarily as a measure to prevent bicyclists from falling into the roadway. The bridge was designated as part of U.S. Bicycle Route 95 in 2021. The main walkway is on the eastern side, and is open for use by both pedestrians and bicycles in the morning to mid-afternoon during weekdays (5:00 a.m. to 3:30 p.m.), and to pedestrians only for

1040-525: A movable barrier since the 1980s, only in March 2005 did the Bridge Board of Directors commit to finding funding to complete the $ 2 million study required prior to the installation of a movable median barrier. Installation of the resulting barrier was completed on January 11, 2015, following a closure of 45.5 hours to private vehicle traffic, the longest in the bridge's history. The new barrier system, including

1120-463: A passenger train and send scores and hundreds to instant death. There are many Southern Pacific locomotives still in revenue service with railroads such as the Union Pacific Railroad , and many older and special locomotives have been donated to parks and museums, or continue operating on scenic or tourist railroads. Most of the engines now in use with Union Pacific have been "patched", where

1200-486: A scaffold (secured by undersized bolts) with twelve men on it fell into and broke through the safety net; two of the twelve survived the 200-foot (61 m) fall into the water. The bridge opened May 27, 1937. The Round House Café diner was then included in the southeastern end of the Golden Gate Bridge, adjacent to the tourist plaza which was renovated in 2012. The Round House Café, an Art Deco design by Alfred Finnila completed in 1938, has been popular throughout

1280-404: A site near the bridge. As part of the fiftieth anniversary celebration in 1987, the Golden Gate Bridge district again closed the bridge to automobile traffic and allowed pedestrians to cross it on May 24. This Sunday morning celebration attracted 750,000 to 1,000,000 people, and ineffective crowd control meant the bridge became congested with roughly 300,000 people, causing the center span of

1360-408: A thin, flexible roadway would flex in the wind, greatly reducing stress by transmitting forces via suspension cables to the bridge towers. Although the Golden Gate Bridge design has proved sound, a later Moisseiff design, the original Tacoma Narrows Bridge , collapsed in a strong windstorm soon after it was completed, because of an unexpected aeroelastic flutter . Ellis was also tasked with designing

1440-557: Is $ 10.25. Southern Pacific Transportation Company The Southern Pacific ( reporting mark SP ) (or Espee from the railroad initials) was an American Class I railroad network that existed from 1865 to 1996 and operated largely in the Western United States . The system was operated by various companies under the names Southern Pacific Railroad , Southern Pacific Company and Southern Pacific Transportation Company . The original Southern Pacific began in 1865 as

1520-640: Is a suspension bridge spanning the Golden Gate , the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean . The structure links the U.S. city of San Francisco , California —the northern tip of the San Francisco Peninsula —to Marin County , carrying both U.S. Route 101 and California State Route 1 across the strait. It also carries pedestrian and bicycle traffic, and

1600-587: Is designated as part of U.S. Bicycle Route 95 . Recognized by the American Society of Civil Engineers as one of the Wonders of the Modern World , the bridge is one of the most internationally recognized symbols of San Francisco and California. The idea of a fixed link between San Francisco and Marin had gained increasing popularity during the late 19th century, but it was not until the early 20th century that such

1680-478: Is estimated to be 80,000 miles (130,000 km). Each of the bridge's two towers has approximately 600,000 rivets . In the 1960s, when the Bay Area Rapid Transit system (BART) was being planned, the engineering community had conflicting opinions about the feasibility of running train tracks north to Marin County over the bridge. In June 1961, consultants hired by BART completed a study that determined

1760-430: Is officially an orange vermilion called international orange . The color was selected by consulting architect Irving Morrow because it complements the natural surroundings and enhances the bridge's visibility in fog. The bridge was originally painted with red lead primer and a lead-based topcoat, which was touched up as required. In the mid-1960s, a program was started to improve corrosion protection by stripping

1840-414: Is split with three lanes in each direction. From 1968 to 2015, opposing traffic was separated by small, plastic pylons ; during that time, there were 16 fatalities resulting from 128 head-on collisions. To improve safety, the speed limit on the Golden Gate Bridge was reduced from 50 to 45 mph (80 to 72 km/h) on October 1, 1983. Although there had been discussion concerning the installation of

1920-789: The Constitution of the United States . The Southern Pacific Railroad was replaced by the Southern Pacific Company and assumed the railroad operations of the Southern Pacific Railroad. In 1929, Southern Pacific/Texas and New Orleans operated 13,848 route-miles not including Cotton Belt, whose purchase of the Golden State Route circa 1980 nearly doubled its size to 3,085 miles (4,965 km), bringing total SP/SSW mileage to around 13,508 miles (21,739 km). The T&NO

The SP was known for its mammoth back shops at Sacramento, California , which was one of

2080-536: The University of Cincinnati , he placed a brick from his alma mater's demolished McMicken Hall in the south anchorage before the concrete was poured. Strauss also innovated the use of movable safety netting beneath the men working, which saved many lives. Nineteen men saved by the nets over the course of the project formed the Half Way to Hell Club . Nonetheless, eleven men were killed in falls, ten on February 17, 1937, when

2160-413: The 1970s, it also founded a telecommunications network with a state-of-the-art microwave and fiber optic backbone. This telecommunications network became part of Sprint , a company whose name came from the acronym for Southern Pacific Railroad Internal Networking Telephony. The original Southern Pacific Railroad was founded in San Francisco in 1865, by a group of businessmen led by Timothy Phelps with

2240-526: The Denver and Rio Grande Western Railroad to the Southern Pacific Transportation Company, allowing the combined Rio Grande Industries railroad system to use the Southern Pacific name due to its brand recognition in the railroad industry and with customers of both the Southern Pacific Transportation Company and the Denver and Rio Grande Western Railroad. A long time Southern Pacific subsidiary, the St. Louis Southwestern Railway

2320-568: The Golden Gate ," was chosen to commemorate the event. Strauss wrote a poem that is now on the Golden Gate Bridge entitled "The Mighty Task is Done." The next day, President Franklin D. Roosevelt pushed a button in Washington, D.C. signaling the official start of vehicle traffic over the Bridge at noon. Weeks of civil and cultural activities called "the Fiesta" followed. A statue of Strauss was moved in 1955 to

2400-651: The Golden Gate Bridge had the longest suspension bridge main span in the world, at 4,200 feet (1,280 m). Since 1964 its main span length has been surpassed by eighteen bridges ; it now has the second-longest main span in the Americas , after the Verrazzano-Narrows Bridge in New York City. The total length of the Golden Gate Bridge from abutment to abutment is 8,981 feet (2,737 m). The Golden Gate Bridge's clearance above high water averages 220 feet (67 m) while its towers, at 746 feet (227 m) above

2560-501: The SP logo on the front is replaced by a Union Pacific shield, and new numbers are applied over the old numbers with a Union Pacific sticker, however some engines remain in Southern Pacific "bloody nose" paint. Over the past couple years, most of the patched units were repainted into the full Union Pacific scheme and as of January 2019, less than ten units remain in their old paint. Among the more notable equipment is: On August 19, 2006, UP unveiled

2640-565: The SP shops there, new shops and yards were built six miles south of the city at Bayshore. The Alhambra Shops in Los Angeles consisted of 10 buildings and employed 1,500 but declined in importance when the Taylor Yard was built in 1930. The SP was the defendant in the landmark 1886 United States Supreme Court case Santa Clara County v. Southern Pacific Railroad , which is often interpreted as having established certain corporate rights under

2720-544: The Southern Pacific Transportation Company to be taken over by the Union Pacific Corporation ; the parent Southern Pacific Rail Corporation (formerly Rio Grande Industries), the Denver and Rio Grande Western Railroad, the St. Louis Southwestern Railway and the SPCSL Corporation were also taken over by the Union Pacific Corporation. The Union Pacific Corporation merged the Denver and Rio Grande Western Railroad,

2800-584: The Southern Pacific system was a major railroad system incorporating many smaller companies, such as the Texas and New Orleans Railroad and Morgan's Louisiana and Texas Railroad . It extended from New Orleans through Texas to El Paso , across New Mexico and through Tucson , to Los Angeles , through most of California , including San Francisco and Sacramento . Central Pacific lines extended east across Nevada to Ogden, Utah , and reached north through Oregon to Portland . Other subsidiaries eventually included

2880-624: The Southern Pacific-Golden Gate Ferries, Ltd., the largest ferry operation in the world. Once for railroad passengers and customers only, Southern Pacific's automobile ferries became very profitable and important to the regional economy. The ferry crossing between the Hyde Street Pier in San Francisco and Sausalito Ferry Terminal in Marin County took approximately 20 minutes and cost $ 1.00 per vehicle prior to 1937, when

2960-480: The St. Louis Southwestern Railway and the SPCSL Corporation into their Union Pacific Railroad but did not merge the Southern Pacific Transportation Company into the Union Pacific Railroad. Instead, the Union Pacific Corporation merged the Union Pacific Railroad into the Southern Pacific Transportation Company on February 1, 1998; the Southern Pacific Transportation Company became the surviving railroad and at

These were 4-8-8-2 , 2-8-8-2 , and 4-6-6-2 (rebuilt from 2-6-6-2 ) locomotives set up to run in reverse, with the tender attached to the smokebox end of the locomotive. Southern Pacific had a number of snow sheds in mountain terrain, and locomotive crews nearly asphyxiated from smoke in

3120-593: The aim of building a rail connection between San Francisco and San Diego, California . The company was purchased in September 1868 by a group of businessmen known as the Big Four : Charles Crocker , Leland Stanford , Mark Hopkins, Jr. and C. P. Huntington . The Big Four had, in 1861, created the Central Pacific Railroad (CPRR) It later acquired the Central Pacific Railroad in 1885 through leasing. By 1900,

3200-403: The bridge are homes to varieties of wildlife such as bobcats , harbor seals, and sea lions. Three species of cetaceans (whales) that had been absent in the area for many years have shown recent recoveries/(re)colonizations in the vicinity of the bridge; researchers studying them have encouraged stronger protections and recommended that the public watch them from the bridge or from land, or use

3280-618: The bridge as part of the concurrency between U.S. Route 101 and California State Route 1 . Although part of the National Highway System , the bridge is not officially part of California's Highway System . For example, under the California Streets and Highways Code § 401 , Route 101 ends at "the approach to the Golden Gate Bridge" and then resumes at "a point in Marin County opposite San Francisco". The Golden Gate Bridge, Highway and Transportation District has jurisdiction over

3360-443: The bridge to flatten out under the weight. Although the bridge is designed to flex in that way under heavy loads, and was estimated not to have exceeded 40% of the yielding stress of the suspension cables, bridge officials stated that uncontrolled pedestrian access was not being considered as part of the 75th anniversary on Sunday, May 27, 2012, because of the additional law enforcement costs required "since 9/11. " Until 1964,

3440-506: The bridge was not advisable. Aesthetics was the foremost reason why the first design of Joseph Strauss was rejected. Upon re-submission of his bridge construction plan, he added details, such as lighting, to outline the bridge's cables and towers. In 1999, it was ranked fifth on the List of America's Favorite Architecture by the American Institute of Architects . The color of the bridge

3520-486: The bridge's suspension section was capable of supporting service on a new lower deck. In July 1961, one of the bridge's consulting engineers, Clifford Paine, disagreed with their conclusion. In January 1962, due to more conflicting reports on feasibility, the bridge's board of directors appointed an engineering review board to analyze all the reports. The review board's report, released in April 1962, concluded that running BART on

3600-550: The bridge, adjacent to the southeast parking lot. It opened in 2012, in time for the bridge's 75th-anniversary celebration. A cafe, outdoor exhibits, and restroom facilities are located nearby. On the Marin side of the bridge, only accessible from the northbound lanes, is the H. Dana Bower Rest Area and Vista Point, named after the first landscape architect for the California Division of Highways. Lands and waters under and around

3680-692: The bridge. The Golden Gate Bridge and Highway District, authorized by an act of the California Legislature , was incorporated in 1928 as the official entity to design, construct, and finance the Golden Gate Bridge. However, after the Wall Street Crash of 1929 , the District was unable to raise the construction funds, so it lobbied for a $ 30 million bond measure (equivalent to $ 532 million today). The bonds were approved in November 1930, by votes in

3760-541: The cab. After a number of engineers began running their engines in reverse (pushing the tender), Southern Pacific asked Baldwin Locomotive Works to produce cab-forward designs. No other North American railroad ordered cab-forward locomotives. Narrow Gauge Locomotives Until May 1, 1971 (when Amtrak took over long-distance passenger operations in the United States), the Southern Pacific at various times operated

3840-555: The collapse was largely due to construction failure of the vertical hanging clamp. It was also found that poor maintenance, fatigue in the construction material of cable hanger, and the quality of material, may have also impacted the collapse of the bridge. A replacement arch bridge was built in 2013 and formally opened in December 2015. This article about a bridge in Indonesia is a stub . You can help Misplaced Pages by expanding it .

3920-488: The counties affected by the bridge. The construction budget at the time of approval was $ 27 million ($ 492 million today). However, the District was unable to sell the bonds until 1932, when Amadeo Giannini , the founder of San Francisco–based Bank of America , agreed on behalf of his bank to buy the entire issue in order to help the local economy. Construction began on January 5, 1933. The project cost more than $ 35 million ($ 610 million in 2023 dollars ), and

4000-408: The eastern walkway. Bus service across the bridge is provided by one public transportation agency, Golden Gate Transit , which runs numerous bus lines throughout the week. The southern end of the bridge, near the toll plaza and parking lot, is also accessible daily from 5:30 a.m. to midnight by San Francisco Muni line 28. Muni formerly offered Saturday and Sunday service across the bridge on

4080-477: The exception being Humboldt County , whose residents opposed the bridge's construction and the traffic it would generate. Strauss was the chief engineer in charge of the overall design and construction of the bridge project. However, because he had little understanding or experience with cable-suspension designs, responsibility for much of the engineering and architecture fell on other experts. Strauss's initial design proposal (two double cantilever spans linked by

Some passenger steam locomotives bore the Daylight scheme, named after the trains they hauled, most of which had the word Daylight in the train name. The most famous "Daylight" locomotives were the GS-4 steam locomotives . The most famous Daylight-hauled trains were the Coast Daylight and

4480-411: The major contributors to the Golden Gate Bridge lists contractors, engineering-staff, directors and officers: Contractors Engineering staff Directors Officers On December 1, 1951, a windstorm revealed swaying and rolling instabilities of the bridge, resulting in its closure. In 1953 and 1954, the bridge was retrofitted with lateral and diagonal bracing that connected the lower chords of

4560-415: The most photographed, bridge in the world." At the time of its opening in 1937, it was both the longest and the tallest suspension bridge in the world, titles it held until 1964 and 1998 respectively. Its main span is 4,200 feet (1,280 m) and its total height is 746 feet (227 m). Before the bridge was built, the only practical short route between San Francisco and what is now Marin County

4640-569: The most powerful business interests in California, opposed the bridge as competition to its ferry fleet and filed a lawsuit against the project, leading to a mass boycott of the ferry service. In May 1924, Colonel Herbert Deakyne held the second hearing on the Bridge on behalf of the Secretary of War in a request to use federal land for construction. Deakyne, on behalf of the Secretary of War, approved

4720-411: The original paint and repainting the bridge with zinc silicate primer and vinyl topcoats. Since 1990, acrylic topcoats have been used instead for air-quality reasons. The program was completed in 1995 and it is now maintained by 38 painters who touch up the paintwork where it becomes seriously corroded. The ongoing maintenance task of painting the bridge is continuous. Most maps and signage mark

4800-501: The price was reduced to compete with the new bridge. The trip from the San Francisco Ferry Building took 27 minutes. Many wanted to build a bridge to connect San Francisco to Marin County. San Francisco was the largest American city still served primarily by ferry boats. Because it did not have a permanent link with communities around the bay, the city's growth rate was below the national average. Many experts said that

4880-525: The pruning of branch lines. On October 13, 1988, the Southern Pacific Transportation Company (including its subsidiary, St. Louis Southwestern Railway) was taken over by Rio Grande Industries , the parent company that controlled the Denver and Rio Grande Western Railroad (reporting marks D&RGW). Rio Grande Industries did not merge the Southern Pacific Transportation Company and the Denver and Rio Grande Western Railroad together, but transferred direct ownership of

Along with the addition of the SPCSL Corporation route from Chicago to St. Louis, the former mainline of the Chicago, Missouri and Western Railroad that once belonged to the Alton Railroad , the total length of the D&;RGW/SP/SSW system was 15,959 miles (25,684 km). Rio Grande Industries was later renamed Southern Pacific Rail Corporation . By 1996, years of financial problems had dropped Southern Pacific's mileage to 13,715 miles (22,072 km). The financial problems caused

5920-612: Was by boat across a section of San Francisco Bay. A ferry service began as early as 1820, with a regularly scheduled service beginning in the 1840s for the purpose of transporting water to San Francisco. In 1867, the Sausalito Land and Ferry Company opened. In 1920, the service was taken over by the Golden Gate Ferry Company , which merged in 1929 with the ferry system of the Southern Pacific Railroad , becoming

6000-614: Was chosen, using recent advances in bridge design and metallurgy . Strauss spent more than a decade drumming up support in Northern California. The bridge faced opposition, including litigation, from many sources. The Department of War was concerned that the bridge would interfere with ship traffic. The US Navy feared that a ship collision or sabotage to the bridge could block the entrance to one of its main harbors. Unions demanded guarantees that local workers would be favored for construction jobs. Southern Pacific Railroad , one of

6080-546: Was completed ahead of schedule and $ 1.3 million under budget (equivalent to $ 28.9 million today). The Golden Gate Bridge construction project was carried out by the McClintic-Marshall Construction Co., a subsidiary of Bethlehem Steel Corporation founded by Howard H. McClintic and Charles D. Marshall, both of Lehigh University . Strauss remained head of the project, overseeing day-to-day construction and making some groundbreaking contributions. A graduate of

6160-565: Was constructed by state-owned builders PT Hutama Karya at a cost of Rp 150 billion (US$ 16.4 million). On 26 November 2011 at 9:59pm (local time), while workers were performing maintenance on the bridge, a support cable snapped and the structure suffered a catastrophic failure . The roadway fell into the 50-metre-deep (164 ft) Mahakam River below, leaving only the two bridge towers and some support cables remaining. At least 20 people were killed and 40 were injured, with an additional 19 people reported missing. Research findings have shown that

6240-428: Was fully merged into the SP in 1961. In 1969, the Southern Pacific Transportation Company was established and took over the Southern Pacific Company; this Southern Pacific railroad is the last incarnation and was at times called "Southern Pacific Industries", though "Southern Pacific Industries" is not the official name of the company. By the 1980s, route mileage had dropped to 10,423 miles (16,774 km), mainly due to

6320-539: Was initially discussed in 1917 by M.M. O'Shaughnessy , city engineer of San Francisco, and Strauss. The name became official with the passage of the Golden Gate Bridge and Highway District Act by the state legislature in 1923, creating a special district to design, build and finance the bridge. San Francisco and most of the counties along the North Coast of California joined the Golden Gate Bridge District, with

6400-410: Was made in a 1916 San Francisco Bulletin article by former engineering student James Wilkins. San Francisco's City Engineer estimated the cost at $ 100 million (equivalent to $ 2.8 billion in 2023), and impractical for the time. He asked bridge engineers whether it could be built for less. One who responded, Joseph Strauss, was an ambitious engineer and poet who had, for his graduate thesis , designed
