The Iron Horse Trail Bicycle and Pedestrian Overcrossing at Bollinger Canyon Road officially opened to the public on Saturday, July 19, 2025. 

The City of San Ramon, in partnership with Contra Costa Transportation Authority (CCTA), Contra Costa County (CCC), and East Bay Regional Park District (EBRPD), hosted the official opening event, which began at 9 a.m. in the City Hall rotunda with remarks from elected officials and partner agencies, followed by a ribbon cutting at the north entrance to the bridge at 10 a.m. Once the bridge was open, the community participated in a group photo on the bridge.

Project History

In 2009, San Ramon approved the San Ramon Valley Bicycle Pedestrian Corridor Concept Plan, which studied the feasibility of integrating a series of bicycle/pedestrian overcrossings along the Iron Horse Trail at major arterial crossings.

Community outreach and preliminary design for the Iron Horse Trail Overcrossing at Bollinger Canyon Road was completed in 2015, and the conceptual bridge design type was selected.

The final design was approved April 23, 2019, and the official groundbreaking ceremony was held on May 18, 2023.

Public benefits of the Overcrossing at Bollinger Canyon Road include:

  • Improving safety for cyclists and pedestrians
  • Improving traffic flow and reducing vehicle emissions
  • Encouraging pedestrian and bicycle usage along the Iron Horse Trail

More than 82% of funding for the project came from external sources, including grants from the Bay Area Air Quality Management District, MTC’s Transportation for Livable Communities Program and One Bay Area, and the Tri-Valley Transportation Commission; as well as Contra Costa Transportation Authority’s Measure J funding.

Partner agencies for the project include Contra Costa Transportation Authority (CCTA), Contra Costa County (CCC), and East Bay Regional Park District (EBRPD).
