Iron Horse Trail Active Transportation Corridor Study

About the Study

In Contra Costa County, the Iron Horse Trail is 18.5 mile corridor from the Alameda County line to Mayette Avenue in Concord.  Formerly a Southern Pacific Railroad route, the Iron Horse Corridor now features a paved multi-use trail for walking, jogging, and bicycling along with adjacent unpaved or soft trails in some areas. The trail is managed by the East Bay Regional Parks District with Contra Costa County Public Works supporting the management and development of the trail in Contra Costa County.

The Iron Horse Trail Active Transportation Corridor Study is investigating the potential for the corridor to support increased mobility using active transportation – walking, bicycling, and similar modes of travel.  The study will set out a vision for the future of the Iron Horse Trail, consider the trail itself, crossings with streets and highways, and access to the trail.  The objective is to help maximize the safety of trail users, while expanding the number of trips that the trail can support through active transportation.
