The purpose of this program is to reduce congestion and improve safety on highways in San Mateo County. The program divides streets and highways projects into two categories: those that will remove bottlenecks in the most congested commute corridors and those that will improve supplemental roadway projects throughout the county. Both Measure A and Measure W funding can be used for infrastructure improvements to highway network such as interchange modifications, ramp improvements, managed lanes implementation, and may include smaller bicycle and pedestrian improvements. Only Measure W funding can be used to for dedicated pedestrian and bicycle overcrossings.
As defined by the 2004 Transportation Expenditure Plan, Measure A provides the Highway category with a 27.5 percent share of the sales tax revenue collected. Similarly, as defined by the 2018 Congestion Relief Plan, Measure W provides the Highway category with a 22.5 percent share of the sales tax revenue collected. However, four percent of the Measure W Highway program funds are set aside for Transportation Demand Management strategies that reduce countywide congestion (this equates to approximately one percent of all Measure W sales tax revenue). According to the 2020-2024 Transportation Authority Strategic Plan, both measures are projected to produce approximately $1 billion in available funding for this program ($429 million from the remaining 15 years of Measure A and $614 million for the 30 year life of Measure W).
Short Range Highway Plan and Capital Improvement Program
The 2021-2030 Short Range Highway Plan (SRHP) and companion Capital Improvement Program (CIP) were prepared to support future investment decisions for the Measure A Highways and Measure W Countywide Highway Congestion categories. The SRHP is the policy foundation for making highway program investment decisions over the next ten years and uses the adopted Strategic Plan 2020-2024 evaluation criteria to benchmark how projects align with funding priorities for Measures A and W. The CIP identifies eligible Highway program projects and assesses the projected costs versus sales tax revenue over a 10-year period.
