The San Francisco Chronicle is reporting that the Metropolitan Transportation Commission (MTC) has approved a plan to allow solo drivers to pay a toll to drive in Bay Area carpool lanes, turning HOV (high occupancy vehicle) lanes into HOT (high occupancy toll) lanes. The article states:
The system would be phased in over nearly two decades, starting in late 2010 or early 2011, and the first pilot projects would open on two congested corridors: southbound Interstate 680 over the Sunol Grade and both directions of Interstate 580 between Livermore and the I-680 interchange, according to the Metropolitan Transportation Commission, a regional planning and funding agency, which is coordinating the plan.
Eventually, the toll-lane network would be expanded to cover nearly 800 of the region's 1,200 miles of freeway lanes.
The price of the tolls hasn't been decided, but it could start out at a couple of dimes per mile. Motorists would use FasTrak transponders to pay.
