San Francisco-Oakland Bay Bridge to get full length bike lanes?

I always thought that it was just a little silly that the bike lanes that were going to be added to the San Francisco-Oakland Bay Bridge during its retrofit would not travel the bridge’s full length but would only cover the bridge’s eastern span from Oakland to Treasure Island. I was therefore excited to see “Study looks at cost of bike lanes on Bay Bridge” from SF Gate about the recent decision by the Bay Area Toll Authority to fund a study to determine the estimated cost of adding bike lanes on the Bay Bridge’s western span from Treasure Island to San Francisco. The study & cost estimation are not the same as the actual construction of the bike lanes, but the study & cost estimation are a necessary step in the right direction.

From the article:

This morning, a committee of the Bay Area Toll Authority is expected to approve a $1.3 million engineering study and cost analysis to determine how best to attach 5 miles of bike lanes to the west span of the Bay Bridge between Treasure Island and downtown San Francisco – at a cost of $160 million to $390 million.

Bicycle advocates resurrected the notion of bike lanes across the western span after they learned of the planned $1 toll increase to fund seismic repairs on the Antioch and Dumbarton bridges. Figuring that increase might also pay for the west span bike lanes, they asked the Metropolitan Transportation Commission, which also serves as the toll authority, to make that commitment, said Andy Thornley, of the San Francisco Bicycle Coalition.

Wikipedia has a wealth of information about the 1989 Loma Prieta earthquake, the subsequent earthquake damage to the San Francisco-Oakland Bay Bridge, and the eastern span replacement of the San Francisco-Oakland Bay Bridge.
