Iron Horse Trail Bridge at Dublin Boulevard

Iron Horse Trail Crossing Proposed Bridge 3

The Iron Horse Trail Bridge at Dublin Boulevard opened for walkers, runners, and riders on Saturday, November 23, 2024.  The City of Dublin would like to thank all of the community members who joined us for this exciting day, and to the MANY teams who collaborated to make the project possible.

The Iron Horse Regional Trail is a major regional trail for pedestrians and bicyclists through central Alameda and Contra Costa Counties, generally following a former Southern Pacific Railroad right-of-way that was abandoned in 1977.  The Iron Horse Regional Trail was first established in 1986 and is maintained by the East Bay Regional Park District.  The Trail currently passes through the cities of Livermore, Pleasanton, Dublin, San Ramon, Danville, Alamo, Walnut Creek, Concord, and unincorporated areas of the Counties of Contra Costa and Alameda.  The Trail also directly connects to both the Dublin/Pleasanton and Pleasant Hill BART stations.  The Iron Horse Regional Trail has several existing bridges over busy roadways to help improve traffic flow on the roadways and pedestrian/bicycle movement along the Trail.

Project Description

The project is a free-span bridge crossing of the Iron Horse Regional Trail over Dublin Boulevard. Currently, the Trail runs from northwest to southeast as it approaches Dublin Boulevard, which is a heavily traveled east-west roadway.

The project now provides a safe, grade-separated, 230-foot-long bridge for Iron Horse Trail while also facilitating improved traffic flow on Dublin Boulevard.  The entire project length is approximately 1,200 feet.

This project budget is approximately $14 million.  Project funding is from several sources, including Alameda County Measure B/BB, BART Measure RR and, and the Bay Area Air Quality Management District Transportation Fund for Clean Air.

Construction

The project contractor is Goodfellow Sequoia, A JV.  Construction began in April 2022 and will be complete in November 2024.

Iron Horse Trail Feasibility Study

In 2017, the City of Dublin, in partnership with the Alameda County Transportation Commission (ACTC), completed the Iron Horse Trail Feasibility Study.   The goal of the study is to identify improvements along the segment of the Iron Horse Trail, from Dougherty Road to the Dublin/Pleasanton BART Station, that will better connect the Trail to BART, other trails & bikeways, homes and businesses along the trail.
