There doesn't seem to be enough money anywhere to build more roads or to build and operate attractive transit alternatives. Even if money was available, transportation projects take years to complete.
New roads seem to be congested from the day they open.
In the meantime, traffic just gets worse and worse. A new lane is being added. It very well could be. Caltrans will add a two-person carpool lane that will be congested virtually the day it opens. The Sunol Grade already carries enough two-person carpools to fill the new lane.
