Interstate 80 - California

The Carquinez Bridge consists of two spans that carry Interstate 80 over the Carquinez Straits between Crockett in Contra Costa County and Vallejo in Solano County. The northbound (eastbound) span was opened in 1958, and the southbound (westbound) span (Alfred Zampa Memorial Bridge) opened on November 11, 2003. The northbound span is a cantilever span (retrofitted for earthquakes), and the southbound span is a suspension bridge. This photo also shows the original span (opened as part of U.S. 40 on May 11, 1927), which was removed in phases until it was fully dismantled in September 2007. Photo taken 11/28/04.

Routing

Interstate 80 is a major freeway corridor that connects San Francisco, Oakland, Richmond, Vallejo, Fairfield, Vacaville, Davis, Sacramento, Auburn, and Truckee before entering Nevada and continuing east toward Reno, Elko, Salt Lake City, Cheyenne, Omaha, Des Moines, Chicago, Toledo, Cleveland, and New York City. A transcontinental Interstate highway, Interstate 80 serves a great deal of traffic through the 11 states it serves. In California, Interstate 80 generally replaced the original route of U.S. 40 between San Francisco and Reno.

Guide

Transcontinental Interstate 80 begins its easterly journey in San Francisco, the city by the bay. Originating at the interchange with U.S. 101, Interstate 80 immediately ascends to the James Lick Skyway, which was rebuilt in its entirety in the late 2000s. The skyway grants spectacular views of downtown San Francisco, then connects directly to the San Francisco-Oakland Bay Bridge.

The San Francisco-Oakland Bay Bridge carries Interstate 80 across San Francisco Bay. The original bridge was under construction from July 9, 1933, and it opened to traffic on November 12, 1936. The bridge initially carried the dual designation of U.S. 40 and U.S. 50. The Bay Bridge originally consisted of three identifiable segments: western span (suspension bridge with four towers and mid-span anchorage), Yerba Buena Tunnel, and eastern span (a cantilever through truss bridge with an approach causeway). It was also the first suspension bridge to serve San Francisco (as it opened approximately six months prior to the Golden Gate Bridge on U.S. 101 and California 1). The bridge was originally double-decked through all three segments. From 1936 to 1963, the lower deck carried rail, truck, and auto traffic, while the top deck carried auto traffic only in both directions. In 1963, the bridge converted to the current configuration with eastbound traffic on the bottom level and westbound traffic on the top level. The Yerba Buena Tunnel, which passes through Yerba Buena Island, is the largest diameter transportation bore tunnel in the country and possibly the world.

Earthquake retrofitting improved the western (traditional suspension) span between 1994 and 2004, which is now up to current specifications. However, the original eastern span was not up to those specifications, and construction began in 2002 to replace it. After a decade of work, the new eastern span opened to traffic on September 2, 2013. The old eastern span was permanently closed on August 28, 2012, to allow for the shifting of traffic onto the new span. The new eastern span is a single-anchored suspension span with a single tower, along with a long approach causeway coming from Oakland. The causeway was completed first, and the single-anchored suspension segment was completed second. Unlike the tunnel and western span, the eastern span now has side-by-side travel lanes rather than double-deck travel lanes. A bicycle/pedestrian path also follows the eastern span all the way to Yerba Buena Island. The old eastern span, now disconnected from either approach, will be dismantled and removed over the course of several years (probably 2013 to 2015).

Upon leaving the Bay Bridge, Interstate 80 enters the MacArthur Maze, then turns north at Oakland to parallel the bayshore via the Eastshore Freeway. This freeway, which was originally built as U.S. 40, carries Interstate 80 almost due north toward Vallejo. Much of this segment of freeway, especially near Berkeley, is built on landfill.

Prior to reaching Vallejo, Interstate 80 crosses the Carquinez Straits via a steel cantilever bridge and a suspension bridge. The suspension bridge for westbound (southbound) traffic is designated as the Alfred Zampa Bridge. The Zampa Bridge opened on November 11, 2003, and it replaced the original steel cantilever span that had opened on May 21, 1927. Eastbound (northbound) traffic uses another steel cantilever truss span that opened to traffic in 1958. After the Zampa bridge opened in 2003, a project followed thereafter where the 1927 bridge briefly served eastbound traffic while the 1958 span was retrofitted for earthquake safety. Thereafter, the 1927 span was dismantled and removed, gone completely by 2006. Leaving the bridge, Interstate 80 turns northeast at Vallejo, following a well-traveled route between the Bay Area and the capital city of Sacramento.

After passing over the Carquinez Straits, Interstate 80 turns northeast at Vallejo, following a well-traveled route between the Bay Area and the capital city of Sacramento, passing through Fairfield, Vacaville, and Davis along the way, finally crossing the wide Yolo Bypass flood control channel before reaching the capital city metropolitan area. At West Sacramento, Interstate 80 splits into Business Loop I-80/U.S. 50, which serves downtown Sacramento, and regular Interstate 80, which bypasses the city to the north.

After leaving Solano County, Interstate 80 continues along a well-traveled route between the Bay Area and the capital city of Sacramento, passing through Davis and over the wide Yolo Bypass flood control channel before reaching the city of West Sacramento and the capital city metropolitan area. At West Sacramento, Interstate 80 splits into Business Loop I-80/U.S. 50, which serves downtown Sacramento, and regular Interstate 80, which bypasses the city to the north.

As the freeway passes to the north ("over the top of") Sacramento, it passes through several suburbs of Sacramento. As it passes through Roseville and Auburn, Interstate 80 begins its slow ascent into the foothills of the Sierra Nevada. As one of three major all-weather trans-Sierra routes in the winter (others include U.S. 50 and California 88), Interstate 80 is always busy with commercial traffic, tourists, skiers, commuters to Reno, and others. The road narrows to four lanes, but it remains very busy and very fast, especially for downhill (westbound) travelers. Interstate 80 crosses the Donner Summit, one of the highest points on the freeway, then descends into Truckee, a gateway to scenic Lake Tahoe. Passing by a few small towns in the Truckee River valley, Interstate 80 enters Nevada just east of Farad.

History

Changes in San Francisco: Eastern and Central Freeway Proposals

Interstate 80 currently ends at the U.S. 101 interchange, where it meets the Central Freeway. This was not always the planned terminal point for the transcontinental freeway. Prior to August 1965, Interstate 80 was planned to extend across the San Francisco Peninsula along a path roughly located along Fell and Oak Streets (called the Western Freeway) to meet California 1 (which would have also carried the Interstate 280 designation as part of the 1960s plan). Along with the proposed and now cancelled Western Freeway, U.S. 101/Central Freeway (now Octavia Boulevard) between Fell Street (the planned Western Freeway split) east to the current Lick/Central interchange was proposed to carry part of Interstate 80.

The Western Freeway extension of Interstate 80 across the peninsula was killed due to community opposition, community impact, environmental concerns, and cost. At the time the Western Freeway was cancelled, signage for Interstate 80 was retracted off the Central Freeway to end at the interchange between the Central Freeway and James Lick Skyway (today's interchange between U.S. 101 and Interstate 80).

Many years after Interstate 80 was removed from U.S. 101/Central Freeway, the 1989 Loma Prieta Earthquake damaged the Central Freeway, and much of the freeway was ultimately demolished in the early 2000s. It was replaced by at-grade Octavia Boulevard. Aside from the wider-than-normal right of way on Octavia Boulevard (where the Central Freeway used to run), the another remnant of the original freeway plan is the greenbelt area located between Fell and Oak Streets. This linear park was the original proposed east-west segment of Interstate 80 from Octavia Boulevard west to Golden Gate Park.

Changes in San Francisco: James Lick Skyway

The James Lick Skyway portion of Interstate 80 was replaced for a seismic retrofit through 2006 to 2009. Construction resulted in the demolition of several original structures approaching the Bay Bridge. The skyway was originally constructed in 1936 along with the Bay Bridge and was fully replaced in stages during this project. During construction, the highway was routed onto temporary structures located to the north of the existing viaduct, which was demolished and rebuilt from the ground up. Traffic has been switched to the new viaduct, and the temporary structures were later removed.

There have been prior discussions about whether the section of Interstate 80 between U.S. 101 and the Embarcadero exit (which is where Interstate 280 would have connected to Interstate 80 had that connection been constructed) may or may not be an official Interstate. An interesting confluence of facts leads to the reasons behind why the skyway may not be part of the Interstate Highway System:

  • The legislative Route 80 is separated into two sections:
    1. From Route 101 near Division Street in San Francisco to Route 280 near First Street in San Francisco.
    2. From Route 280 near First Street in San Francisco to the Nevada state line near Verdi, Nevada, passing near Oakland, via Albany, via Sacramento, passing near Roseville, via Auburn, via Emigrant Gap, via Truckee and via the Truckee River Canyon.
  • According to Daniel Faigin's page and Chris Sampang, this stretch of Route 80 was originally approved as a chargeable Interstate on 7/7/1947, but it was removed as a chargeable Interstate in August 1965.
  • Several Thomas Brothers California State Map Guides from the 1980s and 1990s show a state route shield on this segment of freeway between U.S. 101 and Proposed Route 280.
  • Joe Rouse mentions that the Caltrans publication about the history of the Interstates in California mentions a mileage change in 1968 where about 5.3 miles of Interstate 80 west of the Embarcadero Freeway was removed from the system. The postmile for the Embarcadero Freeway connections is 5.56. Given the fact that there is a postmile equation on the Skyway, the mileage seems to add up.
  • A 1971 State Highway map shows the Interstate 80 designation ending at the Embarcadero Freeway interchange. The drawings on the map were all black and white, but various colors were used to depict the status of the state's Freeway and Expressway System. Interstate routes were labeled with very wide colored lines; 80 west of the Embarcadero Freeway/Former California 480 is shown as narrower than other Interstate routes.
  • Signage for Interstate 80 is sporadic at best, with overhead signage pointing to southbound U.S. 101 along westbound Interstate 80. However, there are some standalone reassurance shields in place in both directions along this stretch.

In spite of all these facts, there are competing reasons why Interstate 80 is continuous all the way to U.S. 101. Examples include the exit numbering program (which begins at U.S. 101 and proceeds west), the possibility that this segment is non-chargeable Interstate rather than chargeable Interstate, and the overhead signs and shields that display Interstate 80, not California 80. With the recent project to upgrade the James Lick Skyway to Interstate standards, it seems like the skyway can be safely considered part of Interstate 80. Therefore, for our purposes we will continue to consider the skyway section as part of Interstate 80.

Route Switch in West Sacramento and Sacramento

In 1980, Interstate 80 was realigned out of downtown Sacramento and onto former Interstate 880, the Sacramento bypass. This switch occurred because the segment of former Interstate 80 (now Business Loop I-80) between California 99 and California 244 does not meet Interstate standards, and a plan to realign and widen this segment of freeway was scrapped in favor of expanding Sacramento's light rail system. When Interstate 80 was moved onto the bypass, Interstate 880 was decommissioned (with the number saved for later use in the Bay Area). The segment through West Sacramento and downtown Sacramento became designated as Business Loop I-80 and U.S. 50 (secretly Interstate 305), and the north-south portion from U.S. 50 and California 99 northeast to Interstate 80 and California 244 was designated as Business Loop I-80 and California 51.

For much more on this routing change in Yolo and Sacramento Counties, see Business Loop I-80.

Interstate 80 Highway Guides

Scenes Pertaining to Interstate 80
Southbound First Street approaches the onramp to Interstate 80/San Francisco-Oakland Bay Bridge crossing to Oakland and points east. To Los Angeles, follow Interstate 80 east to Interstate 580 east to Interstate 5 south. This overhead sign is a rare back-lit guide sign that was likely placed in the 1960s-1970s time frame. It has been damaged, as a hole is found on the left side of the sign. This toll crossing entrance is located at the intersection between First Street and Harrison Street. Photo taken 04/06/09.
Although the ramp from southbound First Street to Interstate 80 east is signed as a "toll crossing entrance," there is no toll for vehicles crossing eastbound across the Bay Bridge. The toll is currently only collected for westbound travelers. A neutered shield (with no state name) is increasingly common in California, and this brand new shield is one of many that no longer carries the state name (other recent examples include Interstate 5 in northern San Diego County and Kern County). Photo taken 04/06/09.
The onramp to Interstate 80 east was reconstructed as part of the new James Lick Skyway construction. Note the decorative features on the retaining wall of this ramp, which shows the top of one of the suspension towers. Photo taken 04/06/09.
The ramp onto Interstate 80 east from First Street leads onto the lower deck of the Bay Bridge. There are no exits until Yerba Buena Island and Treasure Island. Photo taken 04/06/09.
View of the bay bridge as seen from Exit 2B, Harrison Street from westbound Interstate 80. The exit is a left exit, and it curves in a "U" toward Harrison Street and the Embarcadero. With the reconstruction of the James Lick Skyway and approach to the Bay Bridge, this view is no longer the same. Photo taken 10/16/00.
Side view of the suspension portion of the San Francisco-Oakland Bay Bridge as seen from the Embarcadero in San Francisco. Note the colorful guide signage in place here for such internationally famous attractions as Chinatown, Fisherman's Wharf, and North Beach. Photo taken 10/16/00.
View of the main supports holding up the bridge cables as seen from northbound Embarcadero. Photo taken 10/16/00.
View of the suspension portion of the San Francisco-Oakland Bay Bridge as seen from downtown San Francisco. This photo was taken at the foot of the bridge at this traffic signal for the Embarcadero. Yerba Buena Island, the midway point of the bridge, is visible in the distance, after the fourth suspension tower. The island obscures a view of the steel bridge that represents the eastern half of the heavily traveled span. Photos taken 10/16/00.
This overhead sign is posted on the onramp from Buchanan Street to Interstate 580 west and Interstate 80 east. Interstate 80 travels northeast to Vallejo, Fairfield, Vacaville, Davis, Sacramento, Reno, and Winnemucca. Interstate 580 travels west across the San Pablo Bay to San Rafael and U.S. 101 in Marin County. Photos taken 07/18/09.
This suite of photos shows the progress on the Alfred Zampa Memorial Bridge while it was still under construction in 2002. This was the first suspension bridge constructed in the United States since the early 1970s (the last one constructed was the U.S. 50-301 bridge over Chesapeake Bay). As of November 11, 2003, the Zampa Bridge carries westbound Interstate 80 over the Carquinez Straits. Eastbound traffic will continue to use the 1950s-era steel bridge, while the original 1920s-era bridge is slated for demolition in the coming months. A walking and bicycling path is available along the suspension bridge. Photos taken by Joel Windmiller, 07/21/02.
This suite of photos shows the completed Alfred Zampa Memorial Bridge as seen from Crockett looking north. At the time these pictures were taken, the 1927 span was still intact, since it was briefly used for northbound (eastbound) traffic while the 1958 span was retrofitted. Photos taken 11/28/04.
At the Crockett interchange at the south end of the Alfred Zampa Bridge are these freeway entrance shield assemblies. Photos taken 11/28/04.
From the pedestrian bridge walking north, the southern anchorage of the suspension bridge is visible. In addition, note the teal bridge railing and orange suspension cables, offering a splash of color on the concrete structure. Photos taken 11/28/04.
This series of photos shows the Alfred Zampa Memorial Bridge, starting in Crockett and walking north to Vallejo. Since the bridge is southbound-only, these photos illustrate the bridge if it were taken in the opposite direction. The plaque in the last photo is located at the north end of the bridge and commemorates Alfred Zampa. Photos taken 11/28/04.
Now looking south from the Alfred Zampa Memorial Bridge vista point, the Carquinez Bridge spans dominate the view. In the third photo, note the distant Crockett interchange with Interstate 80 and San Pablo Avenue (Old U.S. 40). This interchange was modified to create the approach from the bridge onto the freeway. Photos taken 11/28/04.
This view of San Pablo Bay is provided from the pedestrian lane on the Alfred Zampa Memorial Bridge. The Carquinez Strait, which carries water from the Sacramento and San Joaquin Rivers through the delta, ends here. Marin County is visible in the distance. Photo taken 11/28/04.
Looking up from the pedestrian bridge is this perspective of the south tower on the Alfred Zampa Memorial Bridge. Photo taken 11/28/04.
Interstate 80 freeway entrance shield assembly at the southern terminus of California 29 in Vallejo (Exit 29A). Photo taken 10/16/00.
Interstate 80 and California 37 trailblazer signage in Vallejo. Photo taken by Trevor Carrier, 2002.
Now in West Sacramento, these signs are posted on westbound West Capitol Avenue near the Exit 81 interchange. Photo taken 08/02/11.
Interstate 80 trailblazer signage. Photo taken by Joel Windmiller, 03/29/01.
In the town of Loomis in western Placer County, Horseshoe Bar Road connects with Interstate 80/Alan S. Hart Freeway at Exit 110. This series of pictures follows northbound Horseshoe Bar Road as it passes over Interstate 80 and connects to the westbound onramp. Photos taken 07/02/13.
These freeway entrance shield assemblies for Interstate 80 are posted in Auburn at the southern end of Nevada Street (at Exit 119A). Photos taken 12/27/04.
It certainly snows in the Sierra Nevada Mountains, as evidenced by these freeway entrance shields partially covered in snow from a recent storm. The last picture shows wood backing of an Interstate 80 freeway entrance shield assembly in the Sierra Nevada. Photos taken by Jeff Royston (01/11/00 and 10/05/12).
A look at the Interstate 80 westbound on-ramp from Donner Pass Road (Historic U.S. 40) near Donner Lake and Truckee. Interstate 80 and Historic U.S. 40 travel separate paths from the lake area (elevation 5,935 feet) to Donner Summit (elevation 7,239 feet). The climb is dramatic and motorists should be prepared to install snow chains in the advent of snow. Photos taken 09/09/05.
