| OLD CONFIGURATION: Interstate 80 eastbound descends below the westbound carriageway ahead of the Second Street under crossing. Remnant ramps from California 480 remain in use between Harrison and Freemont Streets to Interstate 80. California 480, once signed as Interstate 480, was planned as an urban freeway loop from the Financial District northwest to U.S. 101 and the Golden Gate Bridge. Photo taken 11/29/04. |

| Interstate 80/San Francisco-Oakland Bay Bridge east (lower deck) |
|  |
The eastbound Interstate 80 lanes follow the lower deck on the crossing over the San Francisco Bay. The San Francisco-Oakland Bay Bridge carries eight overall lanes. Photos taken 11/29/04. |
 |
 |
There are two exits at the middle of the bridge, one for Treasure Island and the other for Yerba Buena Island. As noted in these overheads, Exit 4A is a left exit for Treasure Island and Exit 4B is a right exit for Yerba Buena Island. Photos taken 03/19/06 and 11/29/04. |

Drawing to within one half mile of the Treasure Island (Exit 4A) off-ramp. Exit 4A joins Treasure Island Road northbound to Avenue Palms over the isthmus that connects Treasure Island to Yerba Buena Island. Treasure Island is a former Navy Base that was decommissioned in 1996. The island was created with fill dredged from San Francisco Bay in the 1930s. Photos taken 03/19/06 and 11/29/04. |

| Interstate 80/Eastshore Freeway east |
| Interstate 80 emerges from underneath the substructure of the bridge and returns to land at Oakland. Interstate 880 (Nimitz Freeway) begins via the Exit 8A off-ramp ahead. Interstate 880 travels south along the eastern bay shore through such communities as San Leandro, San Lorenzo, Newark and Fremont. Photo taken 11/29/04.
|
| Long distance travelers bound for Los Angeles should use Interstate 80 east to Exit 8B (Interstate 580 / MacArthur Freeway east). Truckers should use Interstate 880 south to Interstate 238 east to Interstate 580 in lieu of the MacArthur Freeway. Photo taken 11/29/04.
|
| Nearing "The Maze" the interchange confluence of Interstates 80, 580, and 880 in the city of Oakland. Interstate 880 provides connections to Alameda and Oakland International Airport nearby on its 47.22-mile drive to junction Interstate 280 at San Jose. Exit 8A more specifically connects Interstate 80 east with Grand Avenue ahead of its intersection with Mandela Parkway. Interests to downtown Oakland and Walnut Creek (via California 24 east) should use Exit 8B (Interstate 580 / MacArthur Freeway east). Photo taken 11/29/04.
|
| The southbound beginning of Interstate 880 (Exit 8A) departs Interstate 80 eastbound for Alameda, Oakland International Airport, and San Jose. Interstate 880 replaced California 17 along its routing north of Interstate 280 in 1983. The freeway is best remembered for the disaster of the 1989 Loma Prieto Earthquake when the upper deck of the Nimitz Freeway collapsed onto the lower deck. That portion of freeway was demolished and replaced with the seismically ready Cypress Street Viaduct in the mid 1990s. The viaduct stems south from Grand Avenue to junction Interstate 980. Photos taken 08/16/03 & 11/29/04.

|
| Eastbound Interstate 80 approaches Exit 8B, Junction Interstate 580 east to Hayward and Stockton. The overpass is a connection from westbound Interstate 80 onto Grand Avenue eastbound. Meanwhile, East Interstate 80 and West Interstate 580 merge together onto the Eastshore Freeway for access to Berkeley, Vallejo, and Sacramento. Photo taken 11/29/04.
|
| View of the first exit along southbound Interstate 880 as seen from eastbound Interstate 80 just before the Interstate 580 interchange ("The Maze"). Interstate 880 southbound travels a elevated section over Grand Avenue between Interstate 80 and the Nimitz Freeway. The Grand Avenue off-ramp includes connections to Maritime Street and the former Oakland Army Base below. Photo taken 08/16/03.
|
| Interstate 80 eastbound partitions with the MacArthur Freeway south at Exit 8B. Interstate 580 east leaves Interstate 80 east for downtown Oakland and junction Interstate 980 west & California 24 east. California 24 heads east from Oakland via the Caldecott Tunnel to Orinda, Lafayette, and junction Interstate 680 at Walnut Creek. Interstate 580 meanwhile follows the original corridor of U.S. 50 east from downtown Oakland to Hayward, Castro Valley, Dublin, Livermore, and ultimately Interstate 5 near Tracy. Interstate 205 provides connections to Interstate 5 north for Stockton. Photo taken 11/29/04.

The next three exits serve the city of Berkeley: Exit 10, Junction California 13/Ashby Avenue; Exit 11, University Avenue; and Exit 12, Gilman Street. Photo taken 05/08/05. |
 |
Eight lanes of Interstate 80 & 580 line the Eastern shore of San Francisco Bay through Emeryville and Berkeley. An upcoming exits sign lists the distances to the three Berkeley interchanges (California 13, University Avenue, and Gilman Street). Photo taken 11/26/04. |
 |
Interstate 80 east & 580 west at the Exit 10 directional interchange with California 13 (Ashby Avenue) and Shellmound Street. California 13 travels east through the heart of Berkeley along Ashby Avenue. The state highway turns south at Clairemont Avenue onto Tunnel Road for junction California 24 and the upgrade to the Warren Freeway. Photo taken 05/08/05. |
 |
The Exit 10 off-ramp partitions into ramps for California 13 (Ashby Street) south and Shellmound Street. Shellmound Street enters the city of Emeryville south of California 13. Ashby Street descends into a subway before emerging ahead of the Seventh Street intersection. Photo taken 11/26/04. |
 |
California 13 begins and travels Ashby Street east of the ramp split with Shellmound Street. Ashby Street provides a local through route for Berkeley but is nowhere near as efficient as the area freeway networks. Photo taken 11/26/04. |
 |
Continuing northbound on the Eastshore Freeway through the California 13 (Exit 10) interchange. Note the old style overpasses for the ramps to/from Ashby Street and Interstates 80-580. A small auxiliary guide sign directs motorists bound for the Lawrence Berkeley National Lab and Graduate Theological Union to take Exit 11 (University Avenue). Photo taken 11/26/04. |
 |
Attached to the Exit 10 off-ramp from the Eastshore Freeway south to California 13 south is a button copy upcoming exits sign listing the final three interchanges of the Interstate 80 & 580 overlap. Photo taken 05/08/05. |
 |
Exit 11 provides the most direct route between Interstates 80 & 580 and the University of California, Berkeley. The UC Berkeley campus lies between downtown and Vollmer Peak (el. 1,905 feet) at the east end of University Avenue. Use Exit 11 for Vista Community College as well. Photo taken 11/26/04. |
 |
The first of two sets of Interstate 80 east & 580 westbound reassurance markers resides between California 13 (Exit 10) and University Avenue (Exit 11). The overlap is one of a handful between an Interstate parent and child route. Others that come to mind are Interstates 87 & 287 at Nyack, New York and Interstates 94 & 694 northwest of Minneapolis. Photo taken 11/28/04. |
 |
The Eastshore Freeway travels a causeway between Aquatic Park and Eastshore State Park between California 13 and University Avenue. Pictured here is the advance guide sign for Exit 11 (University Avenue). University Avenue travels west from UC Berkeley to California 123 (San Pablo Avenue), Interstates 80 & 580, and Berkeley Yacht Harbor. Photo taken 11/26/04. |
 |
Since there is no access to University Avenue westbound at Exit 11, interests to the Berkeley Marina should use Exit 12 (Gilman Street) west to the West Frontage Road south. Golden Gate Fields racetrack resides on the swath of land between Interstates 80 & 580 and San Francisco Bay north of Gilman Street. Photo taken 11/28/04. |
 |
Interstate 580 west prepares to split from Interstate 80 east at the Exit 12 ramp departure to Gilman Street. Gilman Street heads east from Eastshore State Park to California 123 (San Pablo Avenue) and Hopkins Street. Photo taken 11/26/04. |
 |
One half mile south of the Interstate 580 (John T. Knox Freeway) west and Interstate 80 (Eastshore Freeway) split at Exit 13A. The Eastshore Freeway enters the city of Albany ahead of the Exit 13A diamond interchange with Buchanan Street. Photo taken 11/26/04. |
 |
An auxiliary lane departs Interstate 80 east & 580 west for Exit 13A (Buchanan Street) ahead of the freeway split. Buchanan Street ventures east from Golden Gate Fields to Marin Avenue and California 123 (San Pablo Avenue). Marin Avenue meets San Pablo Avenue at Albany City Hall. Photo taken 11/28/04. |
 |
Exit 13A leaves the Eastshore Freeway for Buchanan Street and the city of Albany. Interstate 580 departs next from Exit 13B onto the John T. Knox Freeway westbound for the San Raphael Bridge and Marin County. Interstate 80 continues north to central Richmond, San Pablo, Vallejo, and Sacramento. Photo taken 11/28/04. |
 |
Interstate 80 (Eastshore Freeway) eastbound maintains four through lanes at the Exit 13B split with Interstate 580 (John T. Knox Freeway) west. Interstate 580 travels through south Richmond en route to the San Rafael Bridge. The tolled San Rafael Bridge links Richmond with San Quenton and San Rafael (junction U.S. 101). It should be noted that the San Rafael Bridge was briefly touted as Interstate 180 in the early 1980s before Interstate 580 saw extension northwest from Oakland. Photo taken 11/28/04. |
