The San Francisco Bay Area is home to a large number of bike commuters. The geography and demography of the area is a bit unique on the Peninsula from San Jose to San Francisco - unlike "typical" cities with jobs in the center ringed by suburbs of houses, the jobs and residences are dispersed. On my ride from San Francisco to Santa Clara with the googlers there are people who peel off in San Mateo, Foster City, Menlo Park, Palo Alto, Cupertino, and other enclaves I'm missing. We see dozens of cyclists riding the other direction as well.
One problem is that the Peninsula is split by a chunk of asphalt - US Highway 101. There are jobs on each side, and residences on both sides. On the west side, people tend to ride along the Caltrain tracks (or actually take their bike ONTO the Caltrain). On the East side, there is a route that is somewhat more pleasant in spots, including many miles of bucolic bike paths along the bay, populated by a seemingly unending parade of Kiteboarders and Feral Cats.
The problem? At some point you will need to cross the 101. Since it's a limited access freeway, that usually means an overpass with high speed traffic merging in and out of lanes to either exit or enter the freeway. This can lead to tragic results in some cases. But collisions - I believe - are less frequent than one might expect, most likely because people either learn very quickly how to cross the overpasses, find an alternate route, or give up and find another way to get where they are going.
This blog post will be a catchall to inventory a series of upcoming blog posts on the various crossings of 101, from the hairiest and scariest (Holly, Oyster Point) to the most serene (Steven's Creek Bike Path). I'm going to list them here and build the links in as the series grows. Feel free to suggest crossings that I may have missed - the overpasses are obvious but there are all sorts of "hidden" methods of getting from one side to the other. And if you'd like to volunteer to help the project, please do.
