In 2018, when San Mateo County voters passed Measure W by 66.9%, they provided the county with additional resources to improve transit and relieve traffic congestion raised from a ½ cent sales tax. Half of those funds are administered by the San Mateo County Transportation Authority while the remaining half are administered by SamTrans.
The measure, which went into effect in July of 2019, includes funds for highway projects, local street repair, grade separations for Caltrain tracks, expanded bicycle and pedestrian facilities, and improved transit connections. The allocation of Measure W funds is overseen by the Measure W Citizen Oversight Committee.
The TA Strategic Plan guides the evaluation of projects that use this funding. You can read more about the 2020-2024 plan, which was developed through a series of community meetings held throughout the county.
