Highway 12-Jameson Canyon-Full Overnight Closure Starts Friday, August 1 at 11 p.m.
SOLANO COUNTY –Caltrans, the Solano Transportation Authority (STA), and the Napa County Transportation and Planning Agency (NCTPA) are scheduled to switch traffic from the existing roadway configuration on Highway 12-Jameson Canyon in Solano County the night of Friday, August 1.
The switch will require the movement of safety barriers and restriping of traffic lanes. After this switch is completed, motorists will be driving on one new traffic lane eastbound and one new traffic lane westbound on a section of Highway 12 just west of Red Top Road.
Two traffic lanes inside the safety barriers will remain closed until the project nears completion in a few weeks. The temporary configuration will allow crews to complete the final concrete median work.
The entire six-mile widening project with two lanes of eastbound and two lanes of westbound traffic is tentatively scheduled to be completed sometime in September.
Full Overnight Highway Closures
To ensure worker and public safety during Friday night’s full highway closure, eastbound and westbound Highway 12 between Highway 29 and Red Top Road is scheduled to be closed Friday, August 1 at 11 p.m. until Saturday, August 2 at 5 a.m.
