Faced with packed freeways and loaded BART cars, Bay Area voters on Tuesday appeared willing to dig into their own pockets to curb traffic congestion as the region continues to add new jobs and residents.

Partial results Tuesday night showed a measure to raise bridge tolls was headed toward victory. If approved, Regional Measure 3 would raise tolls on all seven state-owned bridges by $3 over six years, not including the Golden Gate, raising an estimated $4.45 billion over the next decade for capital projects and roughly $60 million annually to support transit operations. It needs a simple majority across all nine Bay Area counties to pass.

Carl Guardino, the president and CEO of the Silicon Valley Leadership Group, which helped spearhead the campaign to bring the toll measure to voters, along with the Bay Area Council and urban planning think tank, SPUR, said he was overjoyed with the partial results.

“Along with housing, traffic is the other twin demon that plagues everyone in the region,” he said. “But it also unites us to find true solutions and this measure is a part of that solution.”

The money from the measure is dedicated to help pay for nearly three dozen transportation projects, including new BART cars so the agency can add capacity by running longer trains, the four-station BART extension to San Jose, a Caltrain extension into downtown San Francisco, new toll lanes on freeways throughout the Bay Area, more frequent ferry service and new boats, bicycle and pedestrian improvements, and several interchange improvements, among others.

Roughly 61 percent of the money is dedicated to capital projects to help expand or upgrade public transit, 34.4 percent will go toward highway improvements or other road projects, 1.3 percent is dedicated to supporting transit operations and 3.3 percent will go toward bicycle and pedestrian projects.

Supporters of the measure say the money is badly needed to ease congestion from the anticipated one million jobs that will be added to the Bay Area by 2040 and from the two million new residents those jobs are expected to draw, according to the Metropolitan Transportation Commission, the Bay Area’s transportation planning agency. As the region struggles to add housing near jobs, residents are facing longer and longer commutes.

The average Bay Area commuter now spends 64 minutes commuting to work and back each day, up from 56 minutes in 2011, a 14 percent increase. People taking transit spend even more time going to and from work, almost two hours, or an average of 102 minutes.

It’s a trend that’s all too familiar for Burlingame resident Nanci Nishimura, who used to live in Los Angeles. She sees Bay Area gridlock starting to look a little too close to the home she left in Southern California.

“Something has to be done,” she said.

But opponents of the measure — which included the unlikely allies of some progressives and Republicans — say it burdens those who can least afford it.

“It hurts working people who can’t afford to live near their jobs and they have to commute, so it’d be better to have some sort of other tax than tolls on bridges,” said Linda Roy, 72, a retired college teacher at Evergreen Valley College. “I’m retired so it doesn’t matter to me personally, but I don’t think it’s good for the (region) either.”

Mountain View Mayor Lenny Siegel agreed. He’s hoping his city will approve a ballot measure this year that would tax large employers to help fund transportation projects in his city.

“Some day voters will wake up,” he said. “The entities with all the money should pay their share.”

Others, including Congressman Mark DeSaulnier, D-Concord, have taken issue with the mix of projects proposed, equating them to a grab-bag for politicians’ pet projects that won’t put a dent into easing the region’s commuting woes. The MTC supplied the legislature with an initial mix of projects, largely based on Plan Bay Area 2040, a regional planning roadmap updated every five years. But, in some cases, state senators and representatives added projects or changed the funding amounts of others.

“That’s one thing we need to change,” DeSaulnier said, adding those types of decisions should be “engineering first and politics, second.”

“We should always be trying to do better,” he said.

But with pressure mounting from rising rents and longer commutes, Oakland resident Judith Shahvar, who supported the measure, said something had to be done now, even if it isn’t the final solution.

“It’s gotta happen one way or the other,” she said. “I just want to do anything I can.”
