Due to further funding shortages for seismic retrofit projects, the Bay Area Toll Authority again raised tolls on all Bay Area bridges in its control (this excludes the Golden Gate Bridge) in July 2010. The toll rate for autos on other Bay Area bridges was increased to $5, but in the Bay Bridge a variable pricing tolling scheme based on congestion was implemented. The Bay Bridge congestion pricing scheme charges a $6 toll from 5 a.m. to 10 a.m. and 3 p.m. to 7 p.m., Monday through Friday. During weekends cars pay $5. Carpools before the implementation were exempted but now they pay $2.50, and the carpool toll discount is now also available only to drivers with FasTrak electronic toll devices. The toll remained at the previous toll of $4 at all other times on weekdays. The Bay Area Toll Authority reported that by October 2010 fewer users are driving during the peak hours and more vehicles are crossing the Bay Bridge before and after the 5–10 a.m. period in which the congestion toll goes into effect. Commute delays in the first six months dropped by an average of 15% compared with 2009. For vehicles with at least 3 axles, the toll rate is $5 per axle.
