The portion of Tassajara Road in Dublin and Camino Tassajara in unincorporated San Ramon Valley that has been closed since May for road improvements is set to re-open in time for the afternoon commute Friday.
Dublin public works director Gary Huisingh said the extended road closure was necessary to replace a failing culvert, which runs under Tassajara Road just north of the intersection with Fallon Road near the northern Dublin city limits.
Drivers, bicyclists and pedestrians have been unable to use Tassajara Road/Camino Tassajara to travel between Dublin and the San Ramon/Danville area during the work.
"The aging nine-foot diameter culvert was replaced with an 18-foot diameter culvert that is over 400 feet long. The increased size will allow a more stable flow of water, stop the ongoing deterioration underneath the roadway and will lessen the possibility of emergency road closures in the future," Huisingh said.
The widening of the roadway also will provide greater safety for motorists traveling along that section of Tassajara Road that links Contra Costa and Alameda counties, he added.
