The Mokelumne Trail Bicycle and Pedestrian Overcrossing above state Highway 4 in Brentwood officially opened Wednesday morning.
The 16-foot-wide, 850-foot-long overcrossing provides a critical infrastructure link along the Mokelumne Coast to Crest Trail, which once completed will extend from the Mokelumne River’s headwaters at the Sierra Crest to Martinez. Roughly half of the multi-use trail has been completed.
The new overcrossing also accommodates the potential for future autonomous shuttle travel and provides access and connection to the planned East County Intermodal Transit Center in Brentwood.
Construction work began on the project two years ago almost to the day. Funding for the $13 million bridge came from Measure J, the State Route 4 Bypass Authority and bridge toll funds.
Local officials attended a ribbon-cutting Wednesday for the overcrossing, including Brentwood Mayor Joel Bryant, Contra Costa County Supervisor Diane Burgis, Contra Costa Transportation Authority executive director Tim Haile and CCTA board chair and Danville town councilmember Newell Arnerich.
