Top Bay Area Congestion Hot Spots
If you like to trade commute war stories around the water cooler, now you have some
ammunition: Caltrans has just released a list of the Bay Area's 10 worst congestion
locations for the year 2000. It should come as no surprise that five of the routes go into
and out of Silicon Valley, the region's economic powerhouse, and that three others involve
approaches to the San Francisco-Oakland Bay Bridge -- one on the west side and two on the
east. One of those approaches is the region's No.1 trouble spot: the morning westbound
commute along Interstate 80 in the East Bay, which has been targeted for a
congestion-busting blitz (see "Project
CLEAR" story). Rounding out the list is a stretch of Highway 101 in Marin County.
Overall, the daily hours of delay on Bay Area freeways increased by a staggering 38 percent
between 1999 and 2000, the biggest one-year jump since Caltrans began collecting these
statistics in 1981.
