Truckers’ one-year exemption from last year’s toll hike will end July 1 on San Francisco’s toll bridges.

The Bay Area Toll Authority said the two-phase toll increase for multi-axle vehicles takes effect on July 1 and July 1, 2012. The authority administers toll revenues for the Bay Area’s seven state-owned toll bridges.

Cash tolls for five-axle vehicles will climb to $18 from the current $11.25. In July 2012, cash tolls for vehicles or combinations with three or more axles on these bridges will increase to $5 times the number of axles, so a five-axle truck driver will pay $25.

FasTrak rates for truckers using BATA bridges after July 1 are not yet available.

Toll revenues from the Golden Gate Bridge are administered by the Golden Gate Bridge, Highway and Transportation District, which joined with BATA to operate a single regional FasTrak customer service center.

On the Golden Gate Bridge, drivers of five-axle trucks currently paying $15 cash will fork out $22 in July and $30 the following July. The same truck on the Golden Gate Bridge using FasTrak now paying $12.50 will pay $18.75 beginning this July and $25 starting the next July.
