The San Mateo County Transportation Authority Board recently approved $82.7 million in funding for highway projects to reduce congestion and improve safety on key commute corridors throughout the county.

In May, 23 projects and plans were chosen for funding. The projects include both those that will start construction within the next 18 months and those in other stages.

More than $57 million is allocated with an extra $25 million committed to projects that still need to meet certain conditions for funding. The money comes from Measure A, a sales tax reauthorized in 2009 that has attracted an additional $47.9 million for highway and road improvements in San Mateo County.

The projects include the Broadway interchange and a second eastbound lane to Triton Drive between Foster City Boulevard and Pilgrim Drive in Foster City and widening San Pedro Creek in Pacifica.

The Transportation Authority allocates revenue from Measure A, a voter-approved half-cent sales tax for transportation. A complete list of projects is available at www.smcta.com.
