Eastbound Interstate 80 reaches Exit 27, Pomona Street to Crockett and Junction U.S. 40/San Pablo Avenue. The original button copy sign for Exit 27 indicates Crockett and Port Costa. Pomona Street stems east from San Pablo Avenue (Historic U.S. 40) to Interstate 80 and Carquinez Scenic Drive. Carquinez Scenic Drive straddles the Carquinez Strait Regional Shoreline between Crockett and Port Costa. Crockett itself features port facilities along the south banks of the Carquinez Strait. An exit number was appended to this button copy sign sometime in 2007. Photos taken 07/18/09 and 11/28/04.
A long flyover ramp (Exit 27) descends from Interstate 80 eastbound and curves west to intersect San Pablo Avenue (Historic U.S. 40) and Pomona Street west of the freeway. An adjacent flyover ramp ascends from Pomona Street and downtown Crockett onto the Carquinez Bridge. Photos taken 11/28/04.
Eastbound Interstate 80 approaches the Carquinez Bridge, where the freeway exits Contra Costa County and enters Solano County. The 2004-completed Alfred Zampa suspension Bridge carries Interstate 80 westbound. Photo taken 04/02/04.
This picture shows eastbound Interstate 80 as it approaches the Carquinez Bridge. Eastbound uses a 1950s-era bridge to cross the Carquinez Straits, which connects San Francisco Bay with the Sacramento-San Joaquin River Delta. Westbound uses the new Alfred Zampa bridge, the newest suspension span in the country. The middle bridge represents the original U.S. 40 Carquinez Bridge. The oldest bridge carried westbound traffic until 2004, and briefly carried eastbound traffic in 2005 while crews repaired the adjacent cantilever span for long term use. Photo taken 04/02/04.
Even though westbound now follows a newer bridge, it used to cross the straits over the original bridge that was constructed at a time when Interstate 80 was only U.S. 40. This span, shown to the left of the eastbound bridge, has been demolished now that the new westbound span (the Alfred Zampa suspension bridge at the far left of the picture) was completed. Photos taken 04/02/04 and 11/28/04.
Eastbound Interstate 80 crosses the Carquinez Strait on this cantilever bridge. This high bridge carries four lanes of traffic, and the elaborate support structure for the bridge's truss is a sight to behold. There is a toll booth, but it is located at the east end of the bridge. Only eastbound traffic is required to pay the toll. The Alfred Zampa suspension bridge carries four lanes of traffic, two full shoulders, and a wide sidewalk for pedestrians and bicyclists. There are no plans to replace the eastbound span in the near future, since it was retrofitted to withstand an earthquake. Photos taken 04/02/04.
This series of photos also follows eastbound Interstate 80 as it traverses the 1958 cantilever span. Photos taken 11/28/04.
This series of photos shows Interstate 80 east (north) crossing the Carquinez Strait in July 2007, after the oldest span was mostly dismantled and gone. Photos taken 07/07/07.
Two years later, the oldest span was completely gone, and there was substantially less traffic on this summer's day. All evidence of bridge construction was finally gone. Photos taken 07/18/09.
Coming to the end of the bridge span, eastbound Interstate 80 approaches the north shore. Interstate 80 leaves Alameda County and enters Solano County and the city of Vallejo at this point. Photos taken 04/02/04 and 11/28/04.
