San Mateo County voters narrowly approve $2.4 billion for transit, roads

In the end, it came down to 541 votes.

That was the margin of victory for Measure W — a half-cent sales tax that is expected to generate $2.4 billion over 30 years to pay for bus operations, Caltrain service, improvements to highway interchanges and road repairs in San Mateo County.

The official election results will not be certified until Dec. 6, but with just 296 votes left to be counted, the outcome for this measure won’t change, Jim Izzary, the chief elections officer for San Mateo County, said on Tuesday. Elections this close are not unheard of, but are becoming more common, he said.

“That’s just the nature of this election environment that these measures are hotly debated,” Izzary said, “and people will vote accordingly.”
