"The Bay Bridge, between San Francisco and Oakland, brought far greater damage than benefits to both cities: it pumped up a once unnecessary volume of private traffic between them, at a great expense in expressway building and at a great waste in time and tension, spent crawling through rush-hour congestion. This traffic eventually wiped out, by impoverishment, the excellent rapid transit that had been installed on the Bay Bridge (the Key System) a form of transportation that the citizens of San Francisco have now repentantly voted to restore (the BART system), at an expense far greater than the cost of the original system. The ferry ride across the bay from Oakland was one of the regions greatest recreational resources — an incomparable experience, so exhilarating, at almost any time of the day, that one often sought an excuse for making the journey. It was not a long ride — not more than twenty-five minutes or so, and certainly not longer than the present depressing rush-hour crawl over the bridge." -- Lewis Mumford, 1963
Before the Bay Bridge was linked to the freeway system after 1953 cars got on and off on long cement ramps that hit the city streets on 5th between Harrison and Bryant. In those days car traffic was limited to the top deck, where there were three lanes in each direction.

The September 2013 opening of a new east span of the San Francisco-Oakland Bay Bridge culminates a years-long process to fix the structure after it was damaged during the 1989 Loma Prieta earthquake. Much attention has been paid to the disputes among engineers over the relative safety and stability of the self-suspending design of its signature tower, but little attention has been paid to the context of the Bay Bridge, its half-century role as an impediment to cross-Bay mobility for bicyclists and pedestrians.
The civic celebrations that accompanied the new east span were considerably less exuberant than the Bridge’s original opening in 1936. At that time thousands of people walked onto the Bridge despite it being declared off-limits to pedestrians, a status it has retained to this day. The overarching emphasis on the Bay Bridge as the central artery for automobile traffic to enter and leave San Francisco has prevailed for over a half century, but it didn't start out that way. From its 1936 opening, the Bridge was designed to accommodate a rising torrent of car traffic, but it took more than twenty years before the Bridge was dedicated to motorized transport only. From 1936 to 1958 it had six lanes on the top deck, three each going east and west for automobiles, while the lower deck had three lanes for trucks and buses, and two tracks for three different train systems to bring passengers into downtown San Francisco.

In the first phase of work in 1960, the San Francisco approaches were reconstructed or newly constructed, the upper deck was strengthened to accommodate truck and bus traffic, and the rail section of the lower deck was paved over. The second phase, which took place in 1961, involved rebuilding the Yerba Buena Island Tunnel and viaducts while strengthening the upper deck. To accomplish this without closing the bridge, the division of highways built a temporary bridge that allowed work to go on while keeping half the tunnel open to traffic. During the final phrase, accomplished in 1962 and 1963, workers strengthened the upper deck on the East Bay crossing, and added new lightweight pavement. The reconstructed decks were opened to unidirectional traffic on October 12, 1963.
The restructure of the Bay Bridge between 1958 and 1963 changed the look as well as the functioning of the structure. Although the bridge retained its essential appearance, the alterations brought the structure into the modern postwar function. No longer was it a quaint multipurpose structure with trains and trucks segregated from automobiles. By 1963 the Bay Bridge was a modernized part of the interstate highway system, carrying I-80 to its western terminus and linking the extensive freeway system on the peninsula with the even more extensive freeway network in the East Bay.—Stephen D.

San Francisco’s streets had already been captured by this logic during the late 1920s and early 1930s, as city planners widened roads and imposed new rules on street use, including stop lights, lanes, and crosswalks, all of which was a departure from centuries of unregulated road use by pedestrians and slow-moving vehicles. The impetus to build the Bay Bridge emerged during this period when automobile use was rapidly expanding. Built in just three years during the depths of the Depression, 27 workers died while building it, some falling into the concrete as it was being poured for the anchorage and foundations. Work could not stop to extricate them. Over the three years it took to complete, nearly 8000 men worked on the bridge project.
The automobilistic modernism that shaped popular imagination was on full view at the 1939 Treasure Island Golden Gate International Exposition. There, U.S. Steel created a promotional diorama envisioning San Francisco in the year 1999, depicting the South of Market as a series of massive apartment blocks surrounded by elevated roadways.

At the end of WWII, plans were proposed to build a second Bay Bridge alongside the first one. Mayor Elmer Robinson went to Washington D.C. to lobby against it, gaining success by convincing the Pentagon that it would be too vulnerable to attack. But plans to build more bay crossings were still coming fast and furious. Already a long causeway bridge called the San Francisco Bay Toll-Bridge was opened in 1929, later modernized and reopened in 1967 as the San Mateo-Hayward Bridge. The Richmond-San Rafael Bridge was opened in 1956. But the California Department of Highways (now known as Caltrans) was determined to build at least a “Southern Crossing,” an idea that didn't completely die until the early 1970s.

A frenzy of planning led to a crazy proliferation of proposed tunnels and bridges to connect across the Bay, seen here going north and east from San Francisco.

During this same post-WWII era, highway planners got a huge boost when the federal government launched the interstate highway program. The Bay Bridge was already the western end of the so-called “Lincoln Highway,” but now it would be the western keystone of Interstate 80. Meanwhile, in San Francisco planners were busy laying out and then building freeways through the city. The Bay Bridge had originally landed on 5th Street between Bryant and Harrison, but by the mid-1950s the James Lick Freeway curved behind SF General Hospital and through the South of Market to meet up with the Bridge. The Embarcadero Freeway was also connected directly to the Bridge by the late 1950s.

While all this building was going on, a citizen revolt rose against the highway builders when they saw that thousands of homes in a dozen neighborhoods were slated for demolition to make way for the elevated concrete slabs of the freeway system. It was during this heated controversy over plans to build highways that the Bay Bridge was reconfigured for high speed automobile traffic, five lanes westbound on the top deck and five lanes eastbound on the lower deck. The assumption of the Department of Highways was that most of the new elevated freeways would be built, connecting the south and west sides of San Francisco with the two bridges (Bay and Golden Gate). Much to the shock of the state planners, and even to the whole country, San Francisco refused to build those freeways. It took nearly ten years, but by 1965 the final blow was struck killing plans to build the Panhandle-Golden Gate Park freeway, and also the Golden Gateway freeway that was slated to ring the city’s waterfront, continuing the path of the Embarcadero around to the Golden Gate Bridge.
The Bay Bridge had been reconfigured to maximize auto throughput at 50 mph to connect to the growing network of freeways. Fantasies of smooth flowing high-speed traffic, combined with the incessant advertising of the supposed “freedom of the road,” were nevertheless confronted by the actual conditions: severe traffic jams and daily congestion. The Bridge was usually clogged by rush hour traffic, or severely congested any time of day or night when the inevitable crashes or mechanical breakdowns happened. The “Freeway Revolt” had pushed local planners to embrace BART to replace the commuting capacity they had projected from the expanded freeway systems (and to replace the now destroyed Key surface trolley system), but the same “Revolt” had not led to rethinking how best to use the capacity of the Bay Bridge.
It was not until the 1990s that cycling activists managed to dent the transit professionals’ myopic consensus in favor of automobiles only. Finally Caltrans was pressured into adding a bicycle and pedestrian path to the new east span. But they were not happy about it, and claimed it would cost hundreds of millions more to build. After waiting all this time, the priorities of Caltrans haven’t noticeably changed. They opened the new east span to automobile traffic at the beginning of September, 2013, but the new bike lane is only a bike pier for the next two years. That’s what they claim it will take to finish connecting the bike/ped lane to Yerba Buena Island. Even then, there will be no access to the west span and no way for bicyclists to ride across the Bay Bridge from San Francisco to Oakland or vice versa.
Caltrans claims they are working on a plan to build new decks off the side of the west span, a project expected to take ten years and cost between $500 million and $1 billion! The obvious solution of reorganizing the top deck on the west span, returning it to the original six lanes, reserving one for bicyclists and pedestrians, is somehow unacceptable and is getting no attention from Bridge authorities, transit planners, city politicians or even the bicycle coalitions on both sides of the bay.
