Why the Fourth Bore Sucks



A new report out today provides more compelling evidence for why a fourth bore to the Caldecott Tunnel remains a bad idea. The report by the San Francisco Planning and Urban Research Association points out that the rise of surburban business parks has led to reverse commutes, resulting in more driving and increased greenhouse gas emissions. A fourth bore to the tunnel will only make matters worse. Remember, the fourth bore is to be used primarily to ease traffic going in the opposite direction of the traditional morning and evening commutes.

The report doesn't specifically address the Caldecott, but it advocates for more dense business development in San Francisco. We advocate for the same in downtown Oakland and Berkeley. It may be too late to stop the fourth bore, but it still is a classic example of poor regional planning, and it's bad for the environment.
