The section of the Southern Pacific Railroad running along the East Bay shoreline was completed in 1878. While the Southern Pacific ran steam-powered commuter trains between Oakland and Berkeley, the tracks built along the shoreline were mainly used by transcontinental and Sacramento and San Joaquin Valley trains.
On the portion of the shoreline between Albany and the MacArthur Maze, the Souther Pacific Railroad runs next to the Eastshore Freeway (I-80/I-580). Between the MacArthur Maze and West Oakland, it runs along the Nimitz Freeway (I-880). The railroad also marks much of the path of the original shoreline. The marshy tidelands were filled in to allow the construction of the railroad.
Today, the Union Pacific Railroad runs freight trains along the original Southern Pacific route.

Francis Marion "Borax" Smith consolidated many local electric streetcar lines into the Key System. It officially began operations in 1903. The Key System originated as streetcar lines bringing commuters from Oakland, Berkeley, and Piedmont to the company's pier that jutted three miles out of Oakland into the Bay, running ferries to San Francisco. The rail-to-ferry commute was the fastest way to travel to San Francisco before the construction of transbay infrastructure. According to Oakland Magazine, "In 1957 you could catch a train by the Alameda County Courthouse every half hour and be at the Transbay Terminal in San Francisco in 30 minutes, even during commute hours." The record year for this commute was 1930, when the rail-to-ferry service had 60 million passengers.
In the 1911 map below, the Oakland Traction Company and San Francisco, Oakland & San Jose lines that would later be consolidated into the Key System run parallel to the train tracks. In 1936, the Bay Bridge opened and the Key System's ferry service subsequently lost 3 million passengers. In 1939, a rail track opened on the lower deck of the Bay Bridge. The Key System shared the track with Souther Pacific and Western Pacific, as well. The post-war car-ownership boom, however eventually spelled the demise of the Key System. In 1946, General Motors and Standard Oil of California bought a majority stake in the Key System through their holding company National City Lines. In a move that mirrored National City Lines' actions in major cities across the nation, Key System trains were replaced by busses that could drive the same roads as cars. In 1960, the Key System's operations were taken over by the newly formed AC Transit.
According the Oakland Magazine, "between 1930 and 1950, the number of cars in the Bay Area more than doubled, to more than a million." With many of these people now driving in to San Francisco rather than taking a ferry or train, the Eastshore developed into an important roadway. The Eastshore Highway was a part of US Route 40. It started in El Cerrito and led to the Bay Bridge. Constructing the highway required filling in more of the shoreline past what had already been filled in for the railroad. Filling in the marshy tidelands resulted in the creation of Berkeley's Aquatic Park - a lagoon cut off from the Bay by I-80 (then the Eastshore Highway). Herein lies a relationship between recreational parks and green space and transportation infrastructure.
By the 1950s, the Eastshore Highway, with its three lanes in each direction and lack of onramps was forced to evolve into the present-day Eastshore Freeway. The Eastshore Highway name still exists in the frontage road that runs along the Eastshore Freeway.
Construction of the Eastshore Highway
1936: "Berkeley will be the recreation center of the San Francisco Bay area when the million-dollar waterfront project, as shown here, is completed in the Fall of 1936. The yacht harbor will provide facilities for more than 500 craft and directly faces the Golden Gate. The aquatic park, with swimming, boating and other features will cover approximately a mile and a half of shoreline and provide water sports facilities not found elsewhere on the Pacific Coast."
Seen at the bottom of the map is "S.P. RIGHT OF WAY" which marks the Southern Pacific Railroad. The shape of the eastern side of the Aquatic Park in the image is roughly that of the shoreline before the construction of the Eastshore Highway.
The Eastshore Freeway begins at the Carquinez Bridge and ends at the MacArthur Maze. It contains both I-580 and I-80. In re-engineering the Eastshore Freeway has a total 10 lanes, along with on-ramps and carpool lanes, and now extends to Vallejo. Despite this, it is still one of the most congested stretches of freeway in the Bay Area. Other than the improvement from its previous incarnation, the Eastshore Freeway serves essentially the same primary purpose as the Eastshore Highway - that of allowing people to travel from the East Bay to San Francisco. The coastal nature has been largely restored, however, in projects such as McLaughlin Eastshore State Park. The relatively recent completion of a pedestrian and bike path along the shoreline is a further development that perhaps suggests a slow shifting of cultural values away from the auto-centric ones that produced these freeways.
Below is an interactive map of the portion of the SF Bay Trail that runs along the Eastshore Freeway and beyond to West Oakland. It includes images of each stop along the way, marked with a pin.
The Eastshore Bike Trail is a section of the larger SF Bay Trail, an almost-completed plan to create a 500-mile pedestrian and bike path loop around the entire Bay Area, designed specifically for their use - open sight lines, wide (and generally green) shoulders and barriers separating the path from vehicle traffic. The project also restores natural habitats, has educational signs along the way, and is designed to withstand storm surges, occasional flooding, and other effects of sea level rise.
