The new eastern span opened on September 2, 2013, at an estimated cost of $ 6.4 billion (equivalent to $ 8.26 billion in 2023 ). In May 2022, Caltrans began construction on 18-mile (29 km) high-occupancy toll (HOT) lanes along I-80 between Red Top Road in Fairfield and Leisure Town Road in Vacaville . The project includes converting
516-491: A new freeway through San Francisco . According to the article, the suggested 19th Avenue tunnel would run five miles (8.0 km), from Junipero Serra Boulevard through Golden Gate Park and up to Lake Street, with exits at Brotherhood Avenue, Ocean Avenue, Quintara Street, Lincoln Way , and Geary Boulevard . The Van Ness tunnel would run almost two miles (3.2 km), from about Fell Street to Lombard Street , with exits at Broadway and Geary Boulevard. Along Oak and Fell,

This plant provides countless nutritional seeds for consumption by assorted migratory waterfowl. There are also quite a few nonnative species that are not necessarily wanted in the bypass such as dock and perennial pepperweed . Years with high flows in the Yolo Bypass also benefit fish populations in
688-517: A system of weirs , the bypass diverts floodwaters from the Sacramento River away from the state's capital city of Sacramento and other nearby riverside communities. During wet years, the bypass can be full of water. The main input to the bypass is through the passive Fremont Weir, where water spills from the Sacramento into the bypass if it reaches the 33.5 feet (10.2 m) crest. Downstream,

The California Department of Transportation (Caltrans) sometimes requires vehicles to use snow tires , snow chains , or other traction devices in the mountains during and after snowstorms . Checkpoints are often set up to enforce chain restrictions on vehicles bound for icy or snowy areas. When chain restrictions are in effect, vehicles must have chains on
860-407: Is also open for guided tours for all ages of the public every month. The Yolo Bypass is often used for bird watching, hunting, and hiking. Game species include waterfowl (when the bypass is flooded), ring-necked pheasant, and mourning dove. There are also assorted trails that loop around the wetlands in the Yolo Bypass that may be accessed by the public. Recent modeling shows that increasing flow to

#17328513680421032-486: Is now used for three railroad stations. In 1980, the new I-80 alignment was deleted from the Interstate System. SR 244 was then truncated from its proposed alignment to the only freeway section of the abandoned project in 1994, which is about a mile (1.6 km) long. In 1982–1984, I-880 was reassigned to SR 17 running from Oakland to San Jose , after two to four years of inactivity. On October 17, 1989,
1118-508: Is opened manually when the Sacramento River reaches 27.5 feet (8.4 m) at the I Street Bridge . It was built in 1916 by the City of Sacramento and contains 48 gates over its 1,920-foot (590 m) length; water from the Sacramento Weir flows through the 1 mile (1.6 km) long Sacramento Bypass and drains into the Yolo Bypass. The crest of the Sacramento Weir is at 25 feet (7.6 m) and
1204-462: Is released into the Yolo Bypass at the passive Fremont Weir, near that river's confluence with the Feather River . The Fremont Weir, which lies along the south bank of the Sacramento, is about 32 feet (9.8 m) tall, nearly 12 feet (3.7 m) shorter than the levee on the north bank. When the water reaches the 32 feet (9.8 m) mark it starts to flow out into the Yolo Basin. North of where

The Yolo Basin Wetlands Project is accounted as being one of the largest wetland restoration projects in the Western United States. Habitats in the Yolo Basin Wetlands includes seasonal wetlands, uplands, perennial wetlands, vernal pools and riparian forest . The Bypass also holds species of riparian vegetation such as cottonwoods , black walnut , willows , saltgrass , and other assorted tree and grass species. The Yolo Causeway has one of
1376-551: Is used extensively for roosting by black-crowned night herons , egrets , and white-faced ibis . The giant garter snake also occurs in this habitat. Upland habitats are used extensively by ground nesting birds such northern harriers , western meadowlarks , mallards and ring-necked pheasant. Vegetation is typically dominated by annual rye grass, curly dock and wild sunflower. Rodent populations in these areas provide prey for large numbers of wintering birds of prey . Approximately 1,800 acres (7.3 km) of natural uplands occur in
1462-495: Is very important for neo-tropical migrants such as blue grosbeak, ash-throated flycatchers, and a variety of warbler species. Most riparian vegetation is located along Putah Creek in the central part of the wildlife area. The Yolo Causeway has one of the largest colonies of bats in the state. Thousands of bats, consisting of Mexican free-tailed bats and two other species, roost under the Interstate 80 structure that crosses over
1548-697: The 1964 state highway renumbering . US 40 was one of the original California routes designed in 1926, although its west end was in Oakland with US 101E (then SR 17 , then I-5W , now I-580 / I-880 ) prior to the San Francisco–Oakland Bay Bridge opening in 1936. An auto ferry ran from Berkeley to San Francisco, signed at the ferry landings for US 40. After the San Francisco–Oakland Bay Bridge's construction, US 40, along with US 50 , were extended along
1634-555: The American Association of State Highway and Transportation Officials (AASHTO) rejected the numbering. The state law authorizing the renumbering was passed on September 20, 1963. Signage changes took place by July 1, 1964, and US 40 was decommissioned. US 40 was one of the first US Routes to be decommissioned completely in California. In the Sacramento area, I-80 has been realigned to many routes. In 1964, I-80 used
1720-522: The Beckwourth Pass , at an elevation of 5,221 feet (1,591 m). Driving across the Sierra Nevada became far easier with the construction of I-80 across Donner Summit since that pass is closed only for intense snowstorms. In 1964, Caltrans desired to reduce the number of designated routes in the California state highways system. The Interstate Highway System , designed and built starting in 1956,

#17328513680421892-571: The California Trail and Lincoln Highway . The route has changed from the original plans in San Francisco due to freeway revolts canceling segments of the originally planned alignment. Similarly in Sacramento , the freeway was rerouted around the city after plans to upgrade the original grandfathered route through the city to Interstate Highway standards were canceled. I-80 is recognized as
1978-718: The Carquinez Bridge . I-580 splits from the Eastshore Freeway at an interchange known locally as the "Hoffman Split" in Albany . The section of the Eastshore Freeway between the MacArthur Maze and I-580 (Hoffman) split between Albany is a wrong-way concurrency where the northbound direction is signed as I-80 east and I-580 west, while the southbound direction is signed as westbound I-80 and eastbound I-580. This segment suffers from severe traffic congestion during rush hour due to
2064-515: The Loma Prieta earthquake was responsible for 63 deaths and 3,757 injuries. The San Francisco–Oakland Bay Bridge , which is part of I-80, suffered severe damage, as a 76-by-50-foot (23 m × 15 m) section of the upper deck on the eastern cantilever side fell onto the deck below. The quake caused the Oakland side of the bridge to shift seven inches (18 cm) to the east and caused
2150-700: The Sacramento area. Currently, the freeway runs on a northern bypass of the city, the Beltline Freeway, that was originally designated I-880. The I-80 routing alignment was moved from a route through Sacramento, now US 50 and I-80 Business (I-80 Bus), after the proposed I-80 replacement of the North Sacramento Freeway was canceled. The Beltline Freeway runs northeast from the junction of I-80 and US 50 in West Sacramento across I-5 to its junction northeast of Sacramento with I-80 Bus (which

A January 1968 amendment moved I-280 to its present alignment, degraded I-480 to a state highway, and truncated the origin point of I-80 to the Embarcadero Freeway (then I-280, formerly I-480). Prior to that truncation, I-80 had been defined as from "Route 280 in San Francisco to the Nevada state line near Verdi, Nevada, passing near Division Street in San Francisco, passing near Oakland, via Albany, via Sacramento, passing near North Sacramento, passing near Roseville, via Auburn, via Emigrant Gap, via Truckee and via

The San Francisco Skyway, which had already been signed as part of I-80, has remained a de facto section of I-80 to the present day and remains listed as part of the Interstate in California. In 2000, the San Francisco Chronicle published an article about the proposed construction of
3010-484: The Sacramento River just north of Rio Vista. The water eventually flows into the Sacramento-San Joaquin Delta , just above Rio Vista, and from there into San Francisco Bay . The Yolo Bypass can hold approximately four times the flow of the Sacramento River. Together, the Sacramento River and Yolo Bypass are designed to handle a maximum flow of 600,000 cubic feet per second (1,000,000 m /min), of which

The segment of I-80 in California runs east from San Francisco across
3182-513: The Sacramento Weir, just north of the city of West Sacramento , can also be opened to divert additional waters from the Sacramento if needed. From the west, Cache Creek drains into the bypass. The bypass itself runs south, parallel to the Sacramento, and drains into the Sacramento-San Joaquin Delta , a few miles north of Rio Vista . The bypass is crossed by the Yolo Causeway , a long highway bridge on Interstate 80 , linking West Sacramento and
3268-456: The Sacramento handles 110,000 cu ft/s (190,000 m /min) and the bypass 500,000 cu ft/s (850,000 m /min). This flood management relieves pressure on the surrounding river levee systems and reduces the risk of urban flooding in nearby cities, such as Sacramento or Davis. During wet years, which occur during more than half of all rainy seasons, the Yolo Bypass is flooded; when flooded, it covers an area equal to 1 ⁄ 3
3354-638: The San Francisco Estuary. This is mainly because of increased habitat availability, food supply, larval transport, and reduced predation. The floodplains of the Yolo Bypass are a surprisingly good farming ground for multiple seasonal crops.

When I-80 was first approved, it was to begin at planned I-280 ( SR 1 ) in Golden Gate Park , head east on the never-built Panhandle Freeway , then run south and southeast on the Central Freeway (US 101) to the San Francisco Skyway. The Panhandle Freeway was to be routed through Hayes Valley , passing through Golden Gate Park and terminating at proposed I-280, now SR 1. In 1964, community oppositions forced Caltrans to abandon
3526-473: The Truckee River Canyon", and certain maps had been shown of I-80 running concurrently with US 101 to Fell Street. These changes were made on the state level later that year, but Route 80 was only truncated to US 101. (The Central Freeway remained part of US 101, and the Panhandle Freeway became SR 241.

Agricultural crops in Yolo County amount to about $ 300 million a year. Leftover crop residue is beneficial to animal habitat. The already-harvested land creates foraging area, and food opportunities, such as seeds for mourning dove and
6106-488: The route of present-day I-80 Bus , which was I-80 from 1957 to 1981, when I-80 was realigned along former I-880, routing along what was then the outskirts of Sacramento. US 40 then closely followed I-80 through the Sierra Nevada into Nevada. A portion of old US 40 near Donner Lake is still intact and is an alternate route of I-80. It begins near Soda Springs and ends at Truckee . At one point, it travels right by Donner Lake, unlike I-80, which ascends higher in
6192-528: The seasons. The natural flooding provides an exceptionally good nursery habitat for native fish species, including the endangered Chinook salmon . Juvenile salmon have been found to grow substantially better in the Yolo Bypass than the adjacent Sacramento River . Other special-status wildlife residing in the Yolo Bypass includes giant garter snake , fairy shrimp , bald eagle , Swainson's Hawk , and more. Wildlife managers occasionally flood certain areas to create wetlands for migratory waterfowl . The Yolo Bypass
6278-560: The signed Interstate, known as the San Francisco Skyway or Bayshore Viaduct, is actually part of the Interstate Highway System , although it is consistently shown as I-80 on most maps of San Francisco. The Eastshore Freeway is a segment of I-80 and I-580 along the northeast shoreline of San Francisco Bay . It runs from the MacArthur Maze interchange just east of the eastern end of the San Francisco–Oakland Bay Bridge to
6364-634: The southwest portion of the wildlife area. There are several vernal pools in this area that are home to such invertebrate species as tadpole shrimp, clam shrimp and the endangered conservancy fairy shrimp . Rare and endangered plants include Heckert's pepperweed and Ferris' alkali milk vetch. Grassland bird species in this area include grasshopper sparrow , Savannah sparrow and burrowing owl . Riparian vegetation consists of willows, cottonwoods, black walnut and other tree species. Nesting species here include Swainson's hawks , great-horned owls , wood ducks , tree swallows , and black phoebe . This habitat
6450-446: The state's maximum of 70 mph (110 km/h) as most of the route is in either urban areas or mountainous terrain. I-80 has portions designated as the Eastshore Freeway and Alan S. Hart Freeway. Throughout California, I-80 was built along the corridor of US Route 40 (US 40), eventually replacing this designation entirely. The prior US 40 corridor itself was built along several historic corridors in California, notably
6536-485: The then-new I-80 freeway. The new route also made traveling across the Sierra Nevada far easier. Before construction, US 40 was a two-lane undivided highway with winding turns. This route was often closed in the winter because of the high elevation of the Donner Pass (7,239 feet (2,206 m)), and drivers had to use a much longer route to the north, US 40 Alternate (US 40 Alt), now SR 70 , using
6622-605: The top of the moveable gates is 31 feet (9.4 m); each gate is 38.1 feet (11.6 m) long. Water flowing through the Yolo Bypass is drained through a riparian channel along its southeastern edge, named the Toe Drain. In the Liberty Farms area, the bypass joins first Prospect Slough and then Cache Slough adjacent to the connection of the Sacramento Deep Water Ship Channel . Cache Slough then reconnects with
6708-563: The use of hydrological models. Located at the north end of the Yolo Basin where Putah Creek enters the Yolo Bypass , this part of the Delta is known as the Putah Sinks and hosts a diverse assemblage of wildlife species inhabiting seasonal wetlands, permanent wetlands, riparian forest, uplands, vernal pools and agricultural habitats. The extensive use of agriculture achieves its wildlife habitat goals, while providing important operating income. In
6794-755: The wildlife area are managed as seasonal wetlands . They go through an extensive dry period during the spring and summer months. Typically, these ponds are drained on April 1 to stimulate the germination of Swamp Timothy. They may receive a brief summer irrigation and then be flooded in September to provide wetland habitat for migratory waterfowl and shorebirds. Permanent wetlands are flooded year round and tend to be deeper and have more emergent vegetation. These ponds provide important brood water for resident aquatic birds such as mallards , common moorhens and pied-billed grebes . They also provide drinking water for wildlife as well as relief from intense summer heat. This habitat
6880-450: The wildlife area. The Yolo Bypass is a 59,000-acre (240 km) flood control channel that protects Sacramento and other cities from flooding. The wildlife area was created with the understanding that it would remain completely compatible with this primary flood control function. For this reason, there are restrictions on the density of emergent vegetation and riparian trees within the wildlife area. These standards are determined through
6966-442: The winter months from seasonal rainfall and runoff into the three rivers surrounding what is now the city of Sacramento (Sacramento, San Joaquin , and American ). This created a diverse marsh ecosystem that could last more than 100 days. During the 1800s, seasonal flooding would limit travel and access between cities in the Sacramento River valley. Destructive floods in 1862 and 1878 prompted various flood control measures, including
7052-472: Was adding on to the already increased number of US Routes and state highways . In result, the 1964 renumbering truncated US 50 to West Sacramento . The entire route of US 40 was deleted in the Western United States due to the completion of I-80. Also, the number "40" was duplicated along I-40 , at that time, a newly built route in Southern California . I-40 was to be numbered I-30 , but
7138-467: Was chosen for the Interstate because of more gradual approaches that aided construction to Interstate Highway standards , which do not allow the sharp curves used by the Donner Pass Road. The grade is three to six percent for 30 miles (48 km). In California I-80 was built along the line of, and eventually replaced, US 40 . The US 40 designation was eliminated in the state as part of
7224-494: Was completed but not open to traffic, where there was a long bridge to nowhere. From 1972 to 1980, I-880 began in West Sacramento as a fork from the original I-80, continues northeast over the Sacramento River to its interchange with I-5 , continues east through the communities of North Sacramento and Del Paso Heights , and ends at an interchange with the Roseville Freeway (I-80). The now-designated Capital City Freeway
7310-484: Was named the Vic Fazio Yolo Wildlife Area in honor of congressman Vic Fazio who lobbied hard for the funds needed to build the project. In 2001, the wildlife area expanded to over 16,000 acres (65 km) with the acquisition of the Glide and Los Rios properties. These acquisitions included the 10,000-acre (40 km) Tule Ranch, a working cattle ranch with extensive vernal pool areas. Most wetland in
7396-575: Was then the original I-80 routing, continuing southwest directly into downtown Sacramento. I-80 was then rerouted along the Beltline Freeway in 1983, while the Capital City Freeway became I-80 Bus, also I-305 and SR 51. I-880 would have intersected SR 244 and then US 50 , but, in 1979, the Sacramento City Council voted to delete the proposed I-80 alignment for rail transit. The constructed I-80/SR 51/SR 244 split
