Iron Horse Trail Overcrossings Project
Posted on 06/27/2025

The City of San Ramon, in partnership with Contra Costa Transportation Authority (CCTA), Contra Costa County (CCC), and East Bay Regional Park District (EBRPD), will host the official opening of the Iron Horse Trail Bicycle and Pedestrian Overcrossing at Bollinger Canyon Road on Saturday, July 19.

The event will begin at 9 a.m. in the City Hall rotunda (7000 Bollinger Canyon Road), with remarks from elected officials and partner agencies, followed by a ribbon cutting at the north entrance to the bridge at 10 a.m. Following the ribbon cutting, the bridge will officially open to the community.

All portions of the event are free, and the public is encouraged to attend. The event will include a group photo opportunity on the bridge, along with commemorative giveaways to celebrate the official opening.

About the Overcrossing

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 by eliminating conflicts between pedestrians/bicycles and vehicles
  • Improving vehicular traffic flow by removing the at-grade crossing
  • Eliminating unsafe crossing maneuvers by pedestrians and bicyclists
  • Encouraging pedestrian and bicycle usage along the Iron Horse Trail
  • Increasing trail use for nearby schools by improving safety at the Bollinger Canyon Road crossing

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).
