Tolls are only collected from westbound traffic at the toll plaza on the east side of the bridge. Since July 2010, the toll rate for passenger cars is $5. For vehicles with more than two axles, the toll rate is $5 per axle. Drivers may either pay by cash or use the FasTrak electronic toll collection device. During peak traffic hours, the two left lanes are designated HOV lanes, allowing carpool vehicles carrying two or more people or motorcycles to pass for a toll of $2.50. The next three lanes are FasTrak-only lanes. During non-peak hours the two HOV lanes become FasTrak-only lanes.
