Caltrans Completes Construction Ahead of Schedule

(Napa)—Caltrans has completed construction of the first of three roundabouts planned for  State Route 29 (SR-29) west of downtown Napa ahead of schedule and anticipates opening the roundabout to traffic on Thursday, Nov 21.

The roundabout accommodates traffic at the SR-29 freeway on- and off-ramps at First Street and will open during the day once required work is completed by the contractor. Caltrans finished this first roundabout before the anticipated spring completion by arranging continuous closure of the offramp for 30 days and by combining various phases of work at the same time.

The early completion of the roundabout saved an estimated $200,000.

There will be an adjustment period as motorists learn to negotiate the new configuration of the intersection. Drivers are asked to slow down as they approach the roundabout, yield to vehicles in the roundabout and watch for signs guiding vehicles.

Detour no longer in place

Motorists can now access First Street and downtown Napa from northbound SR-29The eastbound on-ramp on First Street from Browns Valley Road to SR-29 northbound on-ramp is no longer closed and motorists need not detour any longer.

Detours still in place

As work on the other two roundabouts continues, these detours are in place:

California Boulevard southbound will turn left at Clay Street, then right at Seymour Street, then right at Third Street. Detour ends at California Boulevard.

California Boulevard northbound will turn right at Second Street, then left at Seymour Street, then left at Clay Street and detour ends at California Boulevard.

First Street westbound will turn right at Walnut Street, left on Clay Street and detour ends at California Boulevard.

First Street eastbound from Browns Valley Road will be able to turn right on California Boulevard going south to get to Second Street, then turn left on Second Street to the detour at Seymour Street to go northbound on California Boulevard or to continue east on Second Street to Downtown Napa.

Crews perform final work and inspections prior to opening the new roundabout that accommodates traffic at the SR-29 freeway on- and off-ramps at First Street.
