Highway Guides

Interstate 580/Arthur H. Breed, Jr. Freeway west
After traffic from Eden Canyon Road/Palomares Road merges onto Interstate 580, this reassurance shield is posted at the end of the onramp. Photo taken 11/26/04.
This mileage sign along westbound Interstate 580 provides the distance to the next three exits: Exit 37, Castro Valley Boulevard (old U.S. 50); Exit 35, Strobridge Avenue; and Exit 34, Junction Interstate 238 north (west) to Interstate 880/Nimitz Freeway. Photo taken 11/26/04.
Unincorporated Castro Valley lies generally north of Interstate 580, while the city of Hayward is south of the freeway. Photo taken 11/26/04.
Westbound Interstate 580/Arthur Breed Jr. Freeway skirts Don Castro Regional Recreation Area and reaches Exit 37, Castro Valley Boulevard. Photo taken 11/26/04.
The next three exits along Interstate 580 west are: Exit 35, Strobridge Avenue to California 238/Foothill Boulevard south; Exit 34, Junction Interstate 238 west to Interstate 880; and Exit 33, Carolyn Street/Foothill Boulevard. Photo taken 11/26/04.
The next exit along westbound Interstate 580 is Exit 35, Strobridge Avenue, three-quarters of a mile. Photo taken 11/26/04.
Westbound Interstate 580/Arthur H. Breed Freeway reaches Exit 35, Strobridge Avenue. To California 238, turn north on Strobridge Avenue, then west on Castro Valley Boulevard. After passing under the Interstate 580/Interstate 238 interchange, turn south on Foothill Boulevard. The next exit along westbound Interstate 580 is Exit 34, Junction Interstate 238. Photo taken 11/26/04.
All through trucks to Oakland must use Interstate 880 rather than Interstate 580, so watch for merging trucks prior to the Interstate 238 split. Photo taken 11/26/04.
The next exit along westbound Interstate 580 is Exit 34, Junction Interstate 238 west to Interstate 880/Nimitz Freeway and California 92/San Mateo-Hayward Bridge west to San Mateo. Interstate 238 is merely a connector that travels northwest to Interstate 880/Nimitz Freeway (via Interstate 580 Exit 34). The road has only one interchange, at California 185. Plans call for Interstate 238 to be widened from its current four-lane configuration. There is no direct access to southbound California 238. Photo taken 11/28/04.
Westbound Interstate 580 and Interstate 238 split here at Exit 34. Interstate 238 travels west (signed as north) from here to the interchange with Interstate 880/Nimitz Freeway. Note the lack of control cities on these overhead guide signs. At this point, the Bay Area Rapid Transit (BART) leaves the center median of Interstate 580 and assumes a separate alignment on its way northwest to Oakland. Photo taken 11/26/04.
Interstate 580/MacArthur Freeway west
An Interstate 580 reassurance shield is posted after the Interstate 238 split. From here, Interstate 580 turns in a northwesterly direction toward San Leandro and Oakland, following old U.S. 50. Photo taken 11/26/04.
Upon turning northwest, Interstate 580 becomes part of the MacArthur Freeway. The MacArthur Freeway designation carries Interstate 580 all the way to the Maze interchange where Interstate 580 meets Interstate 80/Eastshore Freeway, Interstate 880/Nimitz Freeway, and Interstate 80/San Francisco-Oakland Bay Bridge. Photo taken 11/26/04.
The next three exits along Interstate 580 west are Exit 33, Carolyn Street/Foothill Boulevard; Exit 32B, Fairmont Road; and Exit 32A, Benedict Drive. Photo taken 11/28/04.
Exit 33 (Carolyn Street/Foothill Boulevard) is the last interchange to serve the unincorporated communities of Castro Valley and Ashland. To 164th Avenue, turn right onto Foothill Boulevard, then turn left onto 164th Avenue. One hundred sixty-fourth Avenue connects to California 185/East 14th Street in Ashland; California 185 will parallel Interstate 580 northwest into Oakland. Photo taken 11/28/04.
Westbound Interstate 580/MacArthur Freeway reaches Exit 33, Carolyn Street/Foothill Boulevard. The next exits are Exit 32B, Fairmont Road and Exit 32A, Benedict Drive. Photo taken 11/28/04.

Exits 32B, 32A, and 31B all serve the city of San Leandro, which is home to 79,452 people per the 2000 Census. San Leandro is a southern suburb of Oakland, located between Oakland and unincorporated San Lorenzo. Incorporated as a town on March 21, 1872, San Leandro functioned briefly as the county seat of Alameda County prior to the 1868 Earthquake (when the courthouse at the intersection of Clarke Street and Davis Street was destroyed, and the county seat moved to Oakland). Through this section of Interstate 580, the westbound direction carries four through lanes. Photo taken 11/28/04.
Westbound Interstate 580/MacArthur Freeway reaches Exit 32B, Fairmont Road. Use Exit 32B to Anthony Chabot Regional Park and Fairmont Ridge.

Photo taken 11/26/04.
Use Exit 19D to Interstate 980/Grove Shafter Freeway west to downtown Oakland and to Interstate 880. In the years following the disastrous Loma Prieta Earthquake of 1989, Interstate 880 between Interstate 980 and Interstate 80 was taken out of service. While the freeway was being rebuilt on its new alignment (completed in 1998), Interstate 980 and Interstate 580 served as the connecting route between Interstate 80 and Interstate 880. With the completion of Interstate 880, Interstate 980 has reverted to its role as a collector-distributor for local downtown Oakland traffic. Note that there is no access to Interstate 880 north via Interstate 980 west. Photo taken 11/26/04.
Westbound Interstate 580/MacArthur Freeway meets Interstate 980 and California 24 at this major interchange. The first ramp (Exit 19D) connects to Interstate 980 west to downtown Oakland. The second right (Exit 19C) connects to California 24 east to Berkeley and Walnut Creek via the Caldecott Tunnel. Photo taken 11/26/04.
The right two lanes transition onto Exit 19C, Junction California 24/William Byron Rumford Freeway east to Berkeley and Walnut Creek. The left three lanes continue northwest on Interstate 580 toward the Maze interchange with Interstate 80. Photo taken 11/26/04.
This view of the symmetrical stack interchange with Interstate 980 and California 24 is seen from westbound Interstate 580. The bottom level is Interstate 980 and California 24, while the second level is Interstate 580. The top two levels are the connecting ramps. Photo taken 11/26/04.
The next exit along westbound Interstate 580 is Exit 19B, West Street and San Pablo Avenue. Photo taken 11/26/04.
After the California 24 and Interstate 980 interchange, a set of overheads on the transition ramp from California 24 west to Interstate 580 west can be seen to the right of the westbound main lanes. The freeway now enters the Maze, where Interstate 580, Interstate 80, and Interstate 880 all merge together to connect with the San Francisco-Oakland Bay Bridge. Photos taken 11/26/04 and 05/08/05.
An Interstate 580 reassurance shield is posted shortly after traffic from California 24 merges onto the freeway. Photo taken 04/06/09.
For the Juan Bautista de Anza Historic Trail, follow Interstate 80 east/Interstate 580 west (Eastshore Freeway north). Photo taken 04/06/09.
The next exit along westbound Interstate 580/MacArthur Freeway is Exit 19A, which is part of the infamous Maze Interchange: the confluence of Interstate 80, Interstate 580, Interstate 880, and a host of surface streets (including California 123, which is not signed from the freeway). The left lanes exit onto Interstate 80 west (Bay Bridge to San Francisco), while the right lanes carry Interstate 580 west toward Richmond/San Rafael and Interstate 80 northeast to Vallejo and Sacramento. Photos taken 04/06/09 and 05/08/05.
The elevated, five-lane freeway bends toward the west to its junction with Interstate 80 and Interstate 880 at the Maze. Photo taken 05/08/05.
Indeed, these signs are so old that the green overlay panels cover old U.S. 40 and U.S. 50 shields. U.S. 40 is the original designation for Interstate 80, and U.S. 50 is the original designation for Interstate 580. Prior to 1985, this was the western terminus of Interstate 580. It was extended to Marin County via the Richmond-San Rafael Bridge, so now Interstate 580 westbound merges with eastbound Interstate 80 for about five miles. Photos taken 04/06/09, 11/28/04, and 05/08/05.
Transitioning onto the northbound Eastshore Freeway, Interstate 580 west reduces to two through lanes for the first time since leaving the Central Valley. This elevated viaduct takes the freeway through the Maze and will connect it with Interstate 80 east. Photo taken 11/26/04.
Wending its way through the Maze, westbound Interstate 580 finds itself sandwiched between the transition ramp from Interstate 880 north to Interstate 80-580 north and the ramp from Interstate 580 west to Interstate 80/San Francisco-Oakland Bay Bridge west. Note the differences in elevation. Photo taken 11/26/04.
Approaching ground level, the transition ramp from Interstate 880 north flies overhead. Westbound Interstate 580 will merge with eastbound Interstate 80. Despite the difference in directions (how can one be going east and west at the same time), the Eastshore Freeway travels almost due north along the east shore of the San Francisco Bay. At this point, Interstate 580 leaves the city of Oakland and enters the city of Emeryville. Home to 6,882 people as of the 2000 Census, Emeryville is bounded by Oakland to the south and east and by Berkeley to the north. Use Exit 9 (next exit) to Eastshore State Park and the Emeryville Fishing Pier. Photo taken 11/26/04.
Interstate 580 west prepares to merge with Interstate 80 east. Photo taken 05/08/05.
With the Interstate 880 north transition ramp still above the freeway, Interstate 580 west merges with Interstate 80 east. The Interstate 80 traffic arrives from the left. The first exit on the combined Interstate 80-580/Eastshore Freeway is Exit 9, Powell Street/Emeryville. The exit numbers on the combined section uses Interstate 80's mileage. Photo taken 05/08/05.
Transition from Interstate 580 west to Interstate 80/Bay Bridge west
Now looking at the transition ramp from Interstate 580 west to Interstate 80 west, this view shows the three-lane ramp swinging northwest through the Maze. Photo taken 04/06/09.
As the ramp turns, the San Francisco Bay comes into view. The toll plaza for the Bay Bridge is located after the base of the ramp. Photos taken 04/06/09.
A high occupancy vehicle lane forms on the left side of the freeway ramp. Mainline Interstate 80 traffic merges in from the right. Photo taken 04/06/09.
The next exit along Interstate 80 west will be Exit 8A, West Grand Avenue. After that exit, Interstate 80 will ascend the San Francisco-Oakland Bay Bridge en route to the city of San Francisco. Photo taken 04/06/09.
Interstate 80 east, Interstate 580 west, and Eastshore Freeway north
For pictures of the shared alignment between Interstate 580 and Interstate 80, please see the eastbound Interstate 80 in Alameda and San Francisco Counties page.
Interstate 580/John D. Knox Freeway west
Interstate 580 departs from Interstate 80 after Interstate 80's Exit 13B. Two lanes carry Interstate 580 west under the lanes of Interstate 80/Eastshore Freeway. This section of Interstate 580, from here to the Contra Costa County line, was the last section of Interstate 580 to be opened to traffic (the structure was complete in 1991 according to the Caltrans bridge log). Photo taken 05/08/05.
A third lane is added to Interstate 580/John D. Knox Freeway west after clearing the northern Interstate 80 interchange. Photo taken 05/08/05.
A standalone reassurance shield for Interstate 580 is posted shortly thereafter. Photo taken 05/08/05.
The next exit along Interstate 580/Knox Freeway west is Exit 12, Central Avenue. At the gore point, Interstate 580 leaves Alameda County/City of Albany and enters Contra Costa County/city of Richmond. Photo taken 05/08/05.
