The Ross Island Bridge is a cantilever truss bridge that spans the Willamette River in Portland , Oregon . It carries U.S. Route 26 ( Mount Hood Highway ) across the river between southwest and southeast Portland. The bridge opened in 1926 and was designed by Gustav Lindenthal and honors Oregon pioneer Sherry Ross . It is named for its proximity to Ross Island . Although it looks like a deck arch bridge , it is a cantilever deck truss bridge, a rare type in Oregon.

52-545: The bridge was part of the unprecedented period of bridge building in Portland during the 1920s. It was opened on December 21, 1926, and cost $ 2 million to construct. The bridge was designed by a famous engineer named Gustav Lindenthal . The bridge is named for its location close to Ross Island , an island in the Willamette River which measures about one-and-a-half by one mile. The bridge is about 800 feet (240 m) north of

104-510: A civil engineering degree can be obtained after four years of study in the various branches of mathematics, physics, mechanics, etc. The earned degree is called Grado en Ingeniería Civil . Further studies at a graduate school include master's and doctoral degrees. Before the current situation, that is, before the implementation of Bologna Process in 2010, a degree in civil engineering in Spain could be obtained after three to six years of study and

156-463: A category of their own, typically each with their own degrees, either in separate university faculties or at polytechnic schools. In the United States, civil engineers are typically employed by municipalities, construction firms, consulting engineering firms, architect/engineer firms, the military, state governments, and the federal government. Each state requires engineers who offer their services to

208-457: A civil engineer may perform land surveying ; in others, surveying is limited to construction surveying , unless an additional qualification is obtained. Civil engineers usually practice in a particular specialty, such as construction engineering , geotechnical engineering , structural engineering , land development , transportation engineering , hydraulic engineering , sanitary engineering , and environmental engineering . A civil engineer

260-454: A degree. Lindenthal in fact taught himself mathematics , engineering theory, metallurgy , hydraulics , estimating, management , and everything else that a successful bridge engineer needed to know. Nevertheless, the lack of his formal education hindered him from further advancement in Europe, so he decided to emigrate to the United States in 1874. When he first arrived in the United States he

312-677: A five-year program at a polytechnic . Traditionally, students were required to pass an entrance exam on mathematics to start civil engineering studies. This exam was abolished in 2004 for the Flemish Community , but is still organised in the French Community . In Scandinavian countries, "civil engineer" ( civilingenjör in Swedish; sivilingeniør in Norwegian; civilingeniør in Danish)

364-547: A large Hudson River suspension bridge in 1920. This design would have been built at 57th Street in Manhattan, to carry both roadway and railroads, but neither the city nor the railroads were supportive. (Lindenthal's colleague Othmar Ammann developed a scaled-down bridge proposal several years later, which became the George Washington Bridge , completed in 1931.) Lindenthal worked on several other bridge projects around

416-555: A license may not call themselves "civil engineers". In Belgium, Civil Engineer (abbreviated Ir. ) ( French : Ingénieur Civil , Dutch : Burgerlijk Ingenieur ) is a legally protected title applicable to graduates of the five-year engineering course of one of the six universities and the Royal Military Academy. Their speciality can be all fields of engineering: civil , structural , electrical , mechanical , chemical , physics and even computer science . This use of

468-440: A person to obtain a degree in construction engineering . Mechanical engineering , automotive engineering , hydraulics and even sometimes metallurgy are fields in a degree in "Machinery Engineering". Computer sciences , control engineering and electrical engineering are fields in a degree in electrical engineering, while security , safety , environmental engineering , transportation , hydrology and meteorology are in

520-518: A regular university from their military counterparts. Today the degree spans over all fields within engineering, including civil engineering, mechanical engineering, computer science, and electronics engineering, among others. There is generally a slight difference between a Master of Science in Engineering degree and the Scandinavian civil engineer degree, the latter's programme having closer ties with

572-407: A variety of locations and conditions. Much of a civil engineer's work is dealing with non-engineers or others from different technical disciplines, so training should give skills preparing future civil engineers in organizational relationships between parties to projects, cost and time. Many spend time outdoors at construction sites so that they can monitor operations or solve problems onsite. The job

624-480: Is a first professional degree , approximately equivalent to Master of Science in Engineering , and a protected title granted to students by selected institutes of technology . As in English, the word has its origin in the distinction between civilian and military engineers; before the start of the 19th century only military engineers existed, and the prefix "civil" was a way to separate those who had studied engineering in

676-597: Is a direct ramp from US 26 east to Route 99E south, but no northbound access. Likewise, there is access from Route 99E north to the bridge (via Woodward Street and 8th Avenue), but traffic from Route 99E south must exit at Mill Street, about 0.5 miles (0.80 km) to the north, and head down Division Street, 11th Avenue and Milwaukie Avenue to US 26. This same movement is done to reach US 26 east; US 26 west however has direct access to Route 99E north via 9th Avenue and Woodward Street. A fourth direct ramp runs from Route 99E north to US 26 east. The pedestrian walkway simply becomes

728-507: Is concerned with determining the right design for these structures and looking after the construction process so that the longevity of these structures is guaranteed after completion. These structures should also be satisfactory for the public in terms of comfort. Some civil engineers, particularly those working for government agencies, may practice across multiple specializations, particularly when involved in critical infrastructure development or maintenance. Civil engineers generally work in

780-475: Is roughly equivalent to a Bachelor of Science in Scandinavia, to become a "civil engineer" one often has had to do up to one extra year of overlapping studies compared to attaining a B.Sc./M.Sc. combination. This is because the higher educational system is not fully adapted to the international standard graduation system, since it is treated as a professional degree . Today (2009) this is starting to change due to

832-630: Is typically a blend of in-office and on-location work depending on the focus of each engineer. Most engineers work full-time. In most countries, a civil engineer will have graduated from a post-secondary school with a degree in civil engineering, which requires a strong background in mathematics and the physical sciences ; this degree is typically a bachelor's degree , though many civil engineers study further to obtain master's , engineer , doctoral and post doctoral degrees. In many countries, civil engineers are subject to licensure . In some jurisdictions with mandatory licensing, people who do not obtain

884-630: The Atlantic and Great Western Railroad during 1879 to 1881. In 1881, Lindenthal established his own consulting business and built four bridges in the Pittsburgh area: 30th Street Bridge (Herrs Island); Smithfield Street Bridge (over the Monongahela River ; 1883), Youghiogheny River Bridge at McKeesport (1883); and the Seventh Street Bridge ( Allegheny River ; 1884). In 1884, he founded

936-631: The Bologna process . A Scandinavian civilingenjör will in international contexts commonly use the title of "Master of Science in Engineering" and will occasionally wear an engineering class ring . At the Norwegian Institute of Technology (now the Norwegian University of Science and Technology ), the tradition with an NTH Ring goes back to 1914, before the Canadian iron ring . In Spain ,

988-702: The Escuela Especial de Ayudantes de Obras Públicas (now called Escuela Universitaria de Ingeniería Técnica de Obras Públicas de la Universidad Politécnica de Madrid ), founded in 1854 in Madrid. Both schools now belong to the Technical University of Madrid . In Spain, a civil engineer has the technical and legal ability to design projects of any branch, so any Spanish civil engineer can oversee projects about structures, buildings (except residential structures which are reserved for architects), foundations, hydraulics,

1040-528: The truss bridges Lindenthal designed. The use of reinforced concrete was a relatively new idea in bridge construction, with its first use in 1889. The design of the Hell Gate Bridge required a different approach to bridge construction. Nearly all major members of Hell Gate are composed of smaller trusses. The erection of the Hell Gate was carried through without the assistance of any falsework , or work that

1092-750: The Institution of Civil Engineering Surveyors. The description "civil engineer" is not restricted to members of any particular professional organisation although "chartered civil engineer" is. In many Eastern European countries, civil engineering does not exist as a distinct degree or profession but its various sub-professions are often studied in separate university faculties and performed as separate professions, whether they are taught in civilian universities or military engineering academies. Even many polytechnic tertiary schools give out separate degrees for each field of study. Typically study in geology , geodesy , structural engineering and urban engineering allows

1144-727: The Multnomah County Commission, and repainting of the Ross Island Bridge was carried out in the summer of 1965. The bridge's color remains blue today, specifically " phthalo blue ". During the Great Depression , the bank of the Willamette near the Ross Island Bridge became the site of a Hooverville . In 1976, ownership was transferred from Multnomah County to the Oregon Department of Transportation . In 2000–2001

1196-787: The North River Bridge Company in New York , with the intent of building a massive bridge over the Hudson River for the Pennsylvania Railroad (PRR). Although the PRR ultimately decided to build tunnels under the river rather than a bridge, the two companies continued their relationship. The PRR hired Lindenthal in 1904 to work on the New York Connecting Railroad and lead the Hell Gate Bridge project. The completed bridge

1300-594: The Union Construction Company, where he gained experience in building incline planes and railroads. Then a year later he decided to join the Swiss National Railroad , where he was hired on as a division engineer in charge of location and construction. While living in Vienna, he attended some public engineering lectures at a local university. However, he never did actually attend the university or receive

1352-471: The bridge underwent a $ 12.5 million renovation in which the deck was replaced, the railings were replaced and upgraded, and the drainage system and lighting were improved. During this renovation, lead paint was discovered, causing some delays and cost overruns. In 2014, work began on a full repainting of the bridge, including removal of the old, lead-based paint and restoration of the bridge's blue color, which had faded since being applied, in 1965. The project

1404-696: The civil engineering profession worldwide. Official members of the ASCE must hold a bachelor's degree from an accredited civil engineering program and be a licensed professional engineer or have five years responsible charge of engineering experience. Most civil engineers join this organization to be updated of current news, projects, and methods (such as sustainability) related to civil engineering as well as contribute their expertise and knowledge to other civil engineers and students obtaining their civil engineering degree. The ICE (Institution of Civil Engineers) founded in 1818, represents, as of 2008, more than 80,000 members of

1456-570: The construction of continuous "moving platform" transit systems in lieu of traditional subway trains on the Brooklyn Bridge and Williamsburg Bridge . While the proposals ultimately remained unbuilt, the city would eventually host a similar (albeit scaled-down) concept sixty years later with the Ford Motor Company "Magic Skyway" attraction at the 1964 New York World's Fair . The North River Bridge Company developed another proposal for

1508-730: The country in the 1920s. Perhaps his most famous and lasting achievement outside of New York is the Sciotoville Bridge , a rail crossing of the Ohio River , completed about the same time as the Hell Gate Bridge. Lindenthal had a difference in opinion with one of the standard engineering practices of the day. Prior to the automobile, train construction represented the majority of transport building that took place. Trains being as heavy as they were made engineers greatly overcompensate and build bridges that were oversized, bulky, and expensive. Lindenthal pointed out that bridges did not have to support

1560-538: The environment, transportation, urbanism, etc. Mechanical and Electrical engineering tasks are included under the Industrial engineering degree. A chartered civil engineer (known as certified or professional engineer in other countries) is a member of the Institution of Civil Engineers , and has also passed membership exams. However, a non-chartered civil engineer may be a member of the Institution of Civil Engineers or

1612-462: The full load of a train as a single point load. Instead, a train moves across the bridge and displaces its load relatively evenly. This was not how the bridges were tested to see if a design worked though. The train's total dead weight was simply added to the bridge, and if it did not hold, it was said to be structurally unstable. Lindenthal's idea of not having to carry the full load allowed bridge designers to create bridges that were still stable, but at

1664-464: The industry's demands. A civil engineer is the better-known of the two; still, the area of expertise remains obfuscated for most of the public. A noteworthy difference is the mandatory courses in mathematics and physics, regardless of the equivalent master's degree, e.g. computer science. Although a "college engineer" ( högskoleingenjör, diplomingenjör, or mellaningenjör in Swedish; høgskoleingeniør in Norwegian; diplomingeniør in Danish)

1716-437: The island and does not connect with, nor does it provide access to, Ross Island. There is a pedestrian walkway on the north side of the bridge, with no barrier between the sidewalk and the westbound right lane. The bridge originally had sidewalks on both sides, but the one on the south side was removed in 1958, to provide more space for vehicles. A pedestrian underpass was built at SW Kelly Avenue and SW Naito Parkway in 1942 by

1768-531: The north side parallel to the ramp to Kelly Avenue (leading to Arthur Street), running to the intersection of Kelly Avenue and Porter Street. At the east end of the bridge, US 26 becomes Powell Boulevard as it passes over Oregon Route 99E ( Pacific Highway East ). Route 99E is a high-speed arterial road , built to near- freeway standards; just to the north it passes over a railroad on the twin Martin Luther King, Jr. Viaduct and Grand Avenue Viaduct . There

1820-627: The north sidewalk of Powell Boulevard, a major street. Gustav Lindenthal Gustav Lindenthal (May 21, 1850 – July 31, 1935) was a civil engineer who designed the Queensboro and Hell Gate bridges in New York City , among other bridges. Lindenthal's work was greatly affected by his pursuit for perfection and his love of art. Having received little formal education and no degree in civil engineering, Lindenthal based his work on his prior experience and techniques used by other engineers of

1872-517: The public and environmental health , as well as improving existing infrastructure that may have been neglected. Civil engineering is one of the oldest engineering disciplines because it deals with constructed environment including planning, designing, and overseeing construction and maintenance of building structures, and facilities, such as roads, railroads, airports, bridges, harbors, channels, dams, irrigation projects, pipelines, power plants, and water and sewage systems. The term "civil engineer "

1924-487: The public to be licensed by the state. Licensure is obtained by meeting specified education, examination, and work experience requirements. Specific requirements vary by state. Typically, licensed engineers must graduate from an ABET -accredited university or college engineering program with a minimum of bachelor's degree, pass the Fundamentals of Engineering exam (FE), obtain several years of engineering experience under

1976-435: The same fields as civil engineers do elsewhere. This degree is equivalent to a Master of Civil Engineering and is obtained after five or six years of study depending on the school granting the title. The first Spanish Civil Engineering School was the Escuela Especial de Ingenieros de Caminos y Canales (now called Escuela Técnica Superior de Ingenieros de Caminos, Canales y Puertos ), established in 1802 in Madrid, followed by

2028-407: The same time much lighter and cheaper. Gustav Lindenthal made bridges that reached new heights for his time. At the time of Hell Gate's completion, it stood as the longest and heaviest steel bridge in the world. Gustav Lindenthal also expanded the idea of "double decker" lanes on his bridges. The Queensboro Bridge is one of the bridges Lindenthal designed that displays the double decker idea. During

2080-414: The state of Oregon in conjunction with the Ross Island Bridge project. The bridge's girders were originally painted black, but in 1955–56 they were repainted green. In 1961, Portland architect Lewis Crutcher suggested repainting all of Portland's downtown-area bridges from black into different colors, and the proposal also included changing the Ross Island Bridge's color to blue. The proposal was approved by

2132-503: The supervision of a licensed engineer, then pass the Principles and Practice of Engineering Exam . After completing these steps and the granting of licensure by a state board, engineers may use the title "Professional Engineer" or PE in advertising and documents. Most states have implemented mandatory continuing education requirements to maintain a license. The ASCE (American Society of Civil Engineers) represents more than 150,000 members of

2184-455: The time Lindenthal practiced engineering, the railroad industry was expanding and replacing many wooden-truss bridges with stronger ones capable of handling the heavier locomotive loads. In order to accommodate these heavier trains, different construction materials were being utilized. The materials being considered by engineers like Lindenthal were reinforced concrete , cable, and steel. Steel and reinforced concrete were two main materials used in

2236-623: The time. Lindenthal was born in Brünn, Austrian Empire, now Brno , Czech Republic in 1850. Lindenthal began to receive practical training in 1866 when he was employed as a mason and carpenter. At the age of 18, Lindenthal left his family to set out to make a life of his own in Vienna , Austria . When he arrived in Vienna he became an assistant in the engineering department for the Empress Elisabeth Railway of Austria. Two years later he joined

2288-487: The title may cause confusion to the English speaker as the Belgian "civil" engineer can have a speciality other than civil engineering. In fact, Belgians use the adjective "civil" in the sense of "civilian", as opposed to military engineers. The formation of the civil engineer has a strong mathematical and scientific base and is more theoretical in approach than the practical oriented industrial engineer ( Ing. ) educated in

2340-591: Was based upon economy as much as anything." At the age of eighty-five, Lindenthal succumbed to a long illness and died shortly after, at his home in Metuchen, New Jersey . Lindenthal's Metuchen property extended northward towards Oak Tree Road into Raritan Township (present-day Edison, New Jersey ), and was later bought by contractor Frank P. Tufaro for the development of the Stephenville community. Up until that point, he remained active as president and chief engineer of

2392-500: Was being "shaky and loose." Lindenthal was given an opportunity to design a replacement, the Smithfield Street Bridge in Pittsburgh. This bridge, completed in 1883 using the structural form of a lenticular truss , could withstand higher stresses, as well as using resources that made it more economical (Approximately $ 23,000 was saved simply by using these materials). "Lindenthal's use of steel instead of iron wherever possible

2444-607: Was completed in early 2019. The west end of the bridge has a full interchange with Naito Parkway ( Oregon Route 10 , Pacific Highway West ), as well as access to and from Arthur Street, which carries US 26 towards Interstate 405 . (Until around 2005, US 26 went north on Naito Parkway and through the south side of downtown Portland.) Access is also provided to and from the north end of Oregon Route 43 (Macadam Avenue - Oswego Highway ), which runs next to Interstate 5 as frontage roads , and allows for access to and from I-5 via slip ramps and U-turns. The pedestrian walkway comes off

2496-630: Was dedicated by Lindenthal and the PRR on March 9, 1917. Lindenthal's career transitioned to public service when he was appointed to lead the New York City Department of Bridges from 1902 through 1903. As Commissioner of Bridges, he managed several projects spanning the East River , and had a major role in designing the Queensboro Bridge and Hell Gate Bridge . In one of the more novel initiatives of his tenure, Lindenthal advocated for

2548-521: Was divided into two main degrees. In the first case, the earned degree was called Ingeniero Técnico de Obras Públicas ( ITOP ), literally translated as "Public Works Engineer" obtained after three years of study and equivalent to a Bachelor of Civil Engineering. In the second case, the academic degree was called Ingeniero de Caminos, Canales y Puertos (often shortened to Ingeniero de Caminos or ICCP ), that literally means "Highways, Canals and Harbors Engineer", though civil engineers in Spain practice in

2600-635: Was employed as a journeyman stonemason for the memorial granite building of the Centennial International Exhibition in Philadelphia in 1876. After completion of this project, Lindenthal worked for the Keystone Bridge Company of Pittsburgh, Pennsylvania , on numerous projects over a three-year period. While working for this company, he gained valuable experience which propelled him to the status of bridge engineer. He worked for

2652-513: Was established by John Smeaton in 1750 to contrast engineers working on civil projects with the military engineers , who worked on armaments and defenses. Over time, various sub-disciplines of civil engineering have become recognized and much of military engineering has been absorbed by civil engineering. Other engineering practices became recognized as independent engineering disciplines, including chemical engineering , mechanical engineering , and electrical engineering . In some places,

2704-589: Was not part of the actual bridge. This was accomplished by building the two halves of the arch simultaneously from each tower. The steel work was supported with the use of cables during construction to carry the load of the arches until they finally met at the center of the span. In another instance, a bridge needed to be constructed over the Monongahela River, after the ferry, which was used for many years beforehand, became outdated. The first bridge, designed by John Roebling , continuously swayed and deflected, and
