San Francisco-Oakland Bay Bridge

Reject the new 'freeway on stilts' design that does not allow Trains!

Heavy Rail Trains used the Bay Bridge, not streetcars! The proposed concrete bridge design does not support trains other than light rail.

The Bay Bridge must be 'future-ready' for trains, to the same weight capacity as the present bridge! Trains went as far as Chico. In the future, High Speed trains and regional trains are most likely to use the Bay Bridge.

Shown: 5-car Interurban Electric Railway #2 train arriving in San Francisco circa 1940.

This 5-car train is the "Dutton Ave. Express" to San Leandro. Express trains should augment BART since BART has always declined express service. Travel time is the main criteria for travel mode choice.

Shown: Transbay Terminal circa 1940 with Interurban Electric Railway #7 express train.

The Bay Bridge rail could save $900 million for High Speed Rail by bypassing the Peninsula. A CaHSRA study states travel time from San Jose to San Francisco via Peninsula is 28 minutes, San Jose to Oakland is 24 minutes. The Bay Bridge route was not studied, but would result in about the same time to San Francisco via Oakland. Bay Bridge rail gives a downtown terminus at Transbay vs. the current Caltrain station now proposed.

The tracks carried more people than all the auto lanes COMBINED. Yet, the tracks used only 20% of the bridge area.

A 1947 California Department of Public Works report shows the San Francisco-Oakland Bay Bridge configuration (1939-1958, right) with five peak direction lanes and two tracks. It states:

"Electric interurban railways have a greater capacity and offer safer and faster transportation (particularly during rush hours) than do other forms of transportation. Therefore, it is essential that the electric railways be retained on the present bridge."

Cross Section of Bridge from State Report

Configuration from the 1947 State Report (above) [enlarge] and possibility for the future (below) along with earthquake retrofitting.

Retaining the existing steel bridge with retrofitting is the best and least costly alternative. Tracks can be easily restored in the future. The number of peak direction lanes would remain unchanged at five lanes, as it always was even with trains. A bicycle path should be attached.

The tracks on the bridge had greater capacity than BART does today because the trains had six parallel tracks to go to for unloading/loading. There is room enough for high speed trains.

Train passengers helped pay for the bridge! The toll was 2.5 cents per passenger each way, included in the fare. This is equivalent to about 50 cents round trip today. It is a significant amount because it's per passenger (not per car).

The A-trains of the Key System (shown) went between San Francisco and San Leandro. The Oakland traffic engineering department wanted trains eliminated near Lake Merritt so the right of way of the trains could be used for more automobile lanes. In 1950, the "heavily used" A-line was severed. As a result of a hostile takeover in 1946 by General Motors Corp., the Key System transit company supported its own destruction.

Many more examples of how General Motors and traffic engineers decimated the train system is contained in the report Conflict of Transportation Competitors.
