The San Mateo County Transportation Authority (TA) is celebrating a $105 million federal grant from the Infrastructure for Rebuilding America grant program (INFRA) that will help close a funding gap for the SR84-US101 Interchange Reimagined Improvement Project

The interchange provides access to San Mateo County residential communities in Redwood City, North Fair Oaks, Menlo Park, and Woodside while supporting industrial activities around the Port of Redwood City, and thousands of jobs at Seaport Center and Pacific Shores.    

The TA is the primary funder of the project and has long championed its objectives. The interchange project is leveraging over $160 million in San Mateo County Measure A transportation tax dollars to build these infrastructure improvements to enhance safety and operational effectiveness, leading to fewer collisions and serious injuries while providing new active transportation facilities for those walking, biking or rolling.   

“We are deeply thankful to U.S. Rep. Kevin Mullin for his dedication in helping secure this vital grant,” said Carlos Romero, Chair of the San Mateo County Transportation Authority Board of Directors. “This funding, which complements our San Mateo County Measure A transportation sales tax, brings us a step closer to achieving a much-anticipated project that will boost bicycle and pedestrian safety, improve traffic efficiency, and set a new benchmark for multimodal access." 

“This is a major win for the region as the U.S. 101/SR84 Interchange Reimagined Project will have widespread mobility and safety benefits. It’s exciting to witness the federal Bipartisan Infrastructure Law having a direct impact here at home,” said U.S. Rep. Kevin Mullin. “I was honored to advocate for federal funding on behalf of this project and I congratulate all of the local stakeholders for their tireless work on this critical infrastructure improvement.” 

The project calls for adding more than four miles of shared use paths, bike lanes, and separated bikeways where none currently exist – providing facilities that serve the varied needs of a wide spectrum of users – whether it’s students scooting to Summit High School from the Redwood City Caltrain Station or employees biking to work at Pacific Shores. 

The reconstruction of the interchange includes replacing all existing ramps, eliminating the existing five-legged intersection at Broadway and Woodside Road, facilitating truck movement through the interchange to US101, and constructing direct-connect flyover ramps among other improvements. 

“Securing the $105 million INFRA grant is a monumental milestone for Redwood City and a testament to the strength of our partnerships and shared commitment to improving critical infrastructure,” said Redwood City Mayor Jeff Gee. “We are especially grateful for the leadership of U.S. Sen. Padilla, U.S. Rep. Mullin, and the collaboration of Caltrans, the SMCTA and our other partners. Together, we are building a safer, more sustainable, and better-connected future for Redwood City and the broader Bay Area.” 

The TA anticipates that this INFRA grant will get the funding package for the project close to the finish line, but additional state funds will likely be needed. The U.S. 101/SR84 Interchange project’s estimated total cost is $384 million.
