Iron Horse Trail Overcrossings – How to Give Your Design Input (2014)

The City of San Ramon is seeking community design input on proposed bicycle/pedestrian overcrossings along the Iron Horse Trail at Bollinger Canyon Road and Crow Canyon Road in San Ramon. The goal of the overcrossings is to enhance safety and reduce delays for both trail and roadway users.
For each of the two proposed overcrossings, the City of San Ramon has posted a survey which includes descriptions and photos of various bridge concepts under consideration.  You can rate each bridge concept in terms of architecture, materials and color on a scale of one to five.
To take one or both surveys, start by visiting the Open San Ramon discussion page at To start the process, select the overcrossing you are interested in. Your selection will expand, giving you a ‘Go to the topic’ button:

Iron Horse Trail Pedestrian Bridge Near Completion

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.

From the Contra Costa Times:

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.

What do you think of the new bridge? Tell us by taking the short survey below.
