As Planetizen reported June 1, the toll schedule for the seven state-owned, Bay Area bridges (not including the Golden Gate Bridge) changes on July 1 (to finance seismic safety projects on Antioch and Dumbarton Bridges), marking the end of the 'free ride' for carpoolers.
"[T]he $2 toll savings could cause some commuters approaching the toll plaza just before 10 a.m. to pull over onto a shoulder and wait - or drive very slowly. CHP spokesman Trent Cross said his agency does not anticipate widespread trouble - or gridlock - on Thursday, but will be prepared."
From SF Examiner: Bay Area bridge tolls climb higher: "The $2.50 car-pooling surcharge and the $6 toll on the Bay Bridge will be applied from 5 to 10 a.m. and 3 to 7 p.m. during the workweek. To apply for the car-pooling discount, motorists are required to purchase a FasTrak transponder. The $6 Bay Bridge toll has been touted by BATA officials as a congestion management tool, with the price hike projected to decrease the maximum delay time on the bridge from 27 minutes to 21 minutes."
