Update: According to project engineers, the crossing will be accessible by September 27th, with the grand opening set for October 2nd.
After months of construction and more than a decade of planning, the Iron Horse Trail Pedestrian/Bike Bridge is near completion. The bridge spans eight lanes of Treat Boulevard in the Pleasant Hill BART area, linking discontinuous sections of the Iron Horse Trail. Upon its opening (rumored to be Friday, August 27th), the overcrossing will allow for pedestrians and bicyclists to safely cross the heavily trafficked road.
Construction on the $6.8 million bridge over the eight lanes of Treat Boulevard began in September of 2009 (see project timeline below). More than 1 million people per year use the Iron Horse Regional Trail, a 24-mile stretch from Dublin to Concord that runs along an old railroad right of way.
Beverly Lane, who represents Central Contra Costa County on the East Bay Regional Park District board, said she thought the bridge would have been completed 10 years ago.
“I am really ecstatic. It’s just going to be so good for the trail users and the people driving down Treat; it will enable people to go over without stopping traffic,” Lane said.

The bridge erection work for the new Iron Horse Pedestrian and Bicycle Bridge over Treat Boulevard requires the closure of the intersection of Treat Boulevard and Jones Road on the weekend of July 23-25, 2010. This bridge is located in the vicinity of the Pleasant Hill BART station. The entire intersection of Treat Boulevard and Jones Road will be shut down during the bridge erection operation. This work will be performed at night in order to minimize traffic disruption.
The bridge erection is scheduled to take 2 nights to complete. During the bridge erection, Treat Boulevard will be closed from Oak Road to Cherry Lane. Jones Road will be closed from the Pleasant Hill BART station to 200 feet south of Treat Boulevard. A detour plan will be in place during the closure. A copy of the detour plan is posted on the County’s website at www.cccpublicworks.org. Work will occur on the following nights from 9:00 p.m. to 10:00 a.m. the following morning:
Friday night, July 23
Saturday night, July 24
Subsequent night operations will take place intermittently between July 25th and August 13th with as-needed lane closures (full intersection closures will not be necessary for these operations) to complete the bridge construction.
During the first three weekends in June, The Contra Costa County Public Works Department will be closing the intersection of Treat Boulevard and Jones Road overnight for the installation of the Iron Horse Trail Pedestrian Bridge.
The closures are scheduled for 9 pm to 10 am the next morning on the following nights:
