North Fair Oaks Bicycle and Pedestrian Railroad Crossing and Community Connections Study

The County of San Mateo is working on the North Fair Oaks Bicycle and Pedestrian Railroad Crossing and Community Connections Study to assess the potential for a pedestrian and bicycle railroad crossing over or under the Caltrain tracks, making it easier to walk and bike in North Fair Oaks and part of adjacent Redwood City. The Study will also explore potential bicycle and pedestrian improvements on local streets in North Fair Oaks that provide connections to the new rail crossing and local destinations on both sides of the tracks. The Study team seeks to develop a community-guided plan that reflects the priorities of the North Fair Oaks community and defines a path forward for implementing the improvements. The Study team includes County staff, community organization Nuestra Casa, and consultants.

Why are we conducting this Study?

The North Fair Oaks Community and part of adjacent Redwood City is separated by the four-track Caltrain Railroad Corridor. The railroad tracks separate residents from local destinations that include, but aren’t limited to, community facilities and services, schools, shopping, and local bus service. There is a need for enhanced and connected bicycle and pedestrian infrastructure.

According to the Unincorporated San Mateo County Active Transportation Plan (ATP), North Fair Oaks has both the highest potential demand for walking and biking and the highest concentration of bicycle and pedestrian collisions per square mile of all San Mateo County unincorporated communities. Making streets easier to walk and bicycle on and making it easier to get to destinations with a new bicycle and pedestrian railroad crossing could help reduce collisions.

The Study aims to create options for a new pedestrian and bicycle crossing that brings the following benefits to the community:

  • Access: Improved access for people walking, rolling, and biking across the rail corridor and nearby neighborhoods.
  • Safety: Safer and well-lit public spaces that are comfortable and inviting for people of all ages and abilities.
  • Equity: Improvements for people traveling without a car that reflect community priorities and achieve local and regional sustainability goals with no housing displacement.
  •  Community Design: Sense of community through attractive public spaces, public art, and structures.
  • Constructability: Minimal construction impacts on the community and feasible project budget.
Timeline of Study starting in 2022 going into winter of 2024. 2022 focuses on existing conditions and development of alternatives, 2023 includes preferred alternatives and a draft study with the final report being published in winter 2024.

The Study area is located within the unincorporated community of North Fair Oaks. The boundaries of the Study area are Middlefield Road to the north, 5th Avenue to the east, El Camino Real to the south and the unincorporated County/Redwood City limit to the west.

Option A Dumbarton Avenue Tunnel is shown in purple. Option B Dumbarton Avenue Bridge is shown in blue. Option C Middlefield Junction Bridge is shown in orange. More details are available in the “Crossing and Community Connection Options” PDF attachment under Study Documents.
