At its June meeting, the San Mateo County Transportation Authority (SMCTA) Board of Directors approved $366.18 million in transportation sales tax funding to improve rail safety and mobility. The funding will advance the Broadway Grade Separation Project in Burlingame and enhance safety at crossings along the Caltrain corridor within the county. 

The Board allocated $21.6 million in Measure A funding to advance the Broadway Grade Separation Project to 100% final design as well as programming $321.6 million for the right-of-way and construction of the project, subject to the receipt of a Federal Railroad Administration Rail Crossing Elimination program grant. The Broadway crossing is currently ranked as the highest-priority grade separation project on the California Public Utilities Commission's statewide Grade Separation Priority List. 

"Improving safety at rail crossings remains one of the most important transportation investments we can make for our communities," said SMCTA Board Chair Julia Mates. "These projects will help protect pedestrians, bicyclists, and motorists while improving mobility and supporting a more reliable transportation network throughout San Mateo County."

The Broadway Grade Separation Project will separate roadway traffic from rail operations at the Broadway crossing, improving safety, reducing traffic delays and enhancing rail operations. The Board also programmed future funding for right-of-way acquisition and construction phases of the project, contingent on securing federal funding and completing a fully funded project budget. 

In addition, the Board allocated $20.52 million for the first phase of the San Mateo County At-Grade Crossings Enhancements Program. The program will provide baseline safety improvements at all 28 at-grade Caltrain crossings in San Mateo County and fund advanced safety enhancements at 10 priority crossings identified through Caltrain's corridor crossing planning efforts. 

The approved funding includes $2.32 million for baseline safety improvements, such as solar markers and delineators, at crossings countywide and $18.2 million for advanced safety enhancements, such as quad crossing gates, at priority locations. Specific improvements will be identified through Caltrain's ongoing Grade Crossing Hazard Assessment update. 

The Board also approved $2.46 million in Measure A Caltrain funding for projects that support transit access, safety and infrastructure improvements throughout San Mateo County, including: 

  • Preliminary engineering and environmental clearance for the Redwood City 4-Track Hub Station and Grade Separations Project. 
  • Station access and safety improvements at multiple Caltrain stations. 
  • Expansion of Caltrain's Institutional Pass Program for San Mateo County participants. 
  • Environmental monitoring associated with the completed 25th Avenue Grade Separation Project in San Mateo. 
  • Preservation and repair work at the historic San Carlos Caltrain Station. 

The investments are funded through Measure A, San Mateo County's voter-approved half-cent transportation sales tax, which dedicates funding to improving transportation safety, mobility and infrastructure throughout the county.
