The city of San Ramon announced lane closures and traffic controls to begin this month during resurfacing projects at Bollinger Canyon Road and Alcosta Boulevard.
Construction on Bollinger Canyon Road from North Dougherty Road to South Dougherty Road is set to begin this week. The pavement will be resurfaced with an asphalt emulsion mixed with small gravel and sand called micro-surfacing seal, officials said.
The project requires that roadway lanes are closed for four to five hours on the days that the new seal treatment is applied. The work is scheduled to take place during weekdays from this Friday (July 24) to Aug. 5 between 8 a.m. and 4:30 p.m.
Resurfacing and other roadway improvements are set to begin at the end of this month on Alcosta Boulevard from Bollinger Canyon Road to Crow Canyon Road on weekdays between 8 a.m. and 5 p.m., city officials said.
The work includes asphalt concrete pavement rehabilitation, subgrade stabilization, concrete curb, gutter, sidewalk, driveway and curb ramp replacements, installation of drilled piers and grade beam, installation of edge subdrain, adjustments of survey monuments and utility structures to grade and installation of pavement striping and markings, according to city officials.
During the construction phase at Alcosta (which is scheduled for completion in November), the width of the roadway will temporarily be reduced to a single lane in each direction at certain times of the day.
Portions of the road between Norris Canyon Road and Bishop Ranch 15 will also have 24-hour lane closures for days. Driveways and cross street intersections will remain accessible, city officials said.
The city advises residents to drive carefully through all construction zones and expect traffic delays during times of construction. In a contract with the city of San Ramon, Livermore-based RGW Construction will be performing the road work for both projects, officials said.

Glad to see the work being done on Alcosta. That street is terrible.
I sure hope the “improvements” will include better traffic and pedestrian signal management. Currently signal management is terrible with poor loop detector timing, non-existent signal synchronization and poor signal cycle length for traffic and pedestrian.
Gene, there is no timing or synchronization of the signals. The garbage system the city installed a few years ago did away with that, but allowed the city council to pat themselves on the back for what they felt was a job well done.
