The Iron Horse Corridor in Contra Costa County stretches 18.5 miles from the Alameda County line northward 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 corridor also includes a number of underground utility lines such as water lines, gas pipelines, and fiber optic systems along with flood control channels, power lines, and portions of a few local streets.
The Iron Horse Corridor Advisory Committee was authorized by the Board of Supervisors on July 22, 1997, to assist Contra Costa County in developing a management program for the Iron Horse Corridor. The advisory committee includes seats for one representative from each jurisdiction or unincorporated community along the corridor (Alamo, City of Concord, City of San Ramon, Town of Danville, City of Walnut Creek, and City of Pleasant Hill); a District II seat; a District IV seat, and a seat for East Bay Regional Park District.
