Iron Horse Trail


The trail between the cities of Concord and Pleasanton was established in 1891 and abandoned in 1978. The whole access trail followed the Southern Pacific Railroad. The Iron Horse Regional Trail as of 2014 spans 32 miles. This trail creates an important recreational and commute for the communities it serves. It connects residential and commercial areas, parks, schools, public transportation, open space space and parks, regional trails, and community facilities.

Path of Travel

The Iron Horse Trail begins near Highway 4 in Concord. It runs through Walnut Creek to the south and crosses under I-680 at Rudgear Road near a Park & Ride to the east. The trail then passes through a residential area that connects with downtown Alamo and the Alamo Square shopping center. Further down south, the trail follows through residential areas and into Danville. The trail then journeys across Danville Boulevard, passes under I-680, and continues south past Pine Valley Road to the Ccounty line in San Ramon. This extends to the Dublin/Pleasanton public transportation and to the Shadow Cliffs Regional Recreation Area. Finally, the Iron Horse Regional Trill continues to extend a distance of about 55 miles. It connects 12 cities from Livermore in Alameda County to Suisun Bay in Contra Costa County.

The Iron Horse Tunnel is an abandoned railroad tunnel in Snoqualmie and is approximately 2 miles long. Its east portal is at Hyak which is close to exit 54 of Interstate 90 and is at an approximate elevation of 2,600 ft (790 m) above sea level. The east portal is just north of Keechelus Lake and the tunnel now serves as part of the Iron Horse Trail.

The tunnel was constructed from 1912-194 by the Milwaukee Road as part of its line from Chicago to Seattle. After renovation a four-inch layer of concrete to the walls and ceiling, a reinforced structure, and a new walking surface were added. The tunnel officially opened on 1914 to the public.
