$390 million for a bike lane on the Bay Bridge?

The article in this morning's Chronicle tells us that the Bay Area Toll Authority is spending $1.3 million to study the idea of spending between $160 million and $390 million to put a bike path on the western span of the Bay Bridge. 

 

That seems nuts to me, but of course the SF Bicycle Coalition likes the idea.

"This is an issue that refuses to die," said John Goodwin, a spokesman for the toll authority and the Metropolitan Transportation Commission.

 

The issue doesn't die because, like Jehovah's Witnesses and the Islamic fanatics, the bike people keep coming at you.
