HSIP Cycle 11 Silverado Trail Intersection Improvements/HSIPL-5921(090)

Napa County was awarded the Highway Safety Improvement Program (HSIP) Cycle 11 grant to improve three critical intersections on Silverado Trail. The Proposed Project involves intersection safety improvements including the installation of flashing beacons, right-turn lanes, and left-turn lanes. The following intersections do not comply with current safety standards and need upgrades and/or installation of warning signage to improve overall visibility. Silverado Trail at Oak Knoll Avenue: Improvements include the installation of flashing beacons on either end of the intersection on Silverado Trail, a new streetlight, widening the apron of the Oak Knoll Avenue intersection with Silverado Trail and installing a right-turn lane on eastbound Oak Knoll Avenue, restriping the median on Silverado Trail north of the intersection to extend the median closer to the intersection, and widening Silverado Trail on the southbound lane towards Oak Knoll Avenue to provide a right-turn lane. Silverado Trail at Zinfandel Lane: Improvements include the installation of flashing beacons on either end of the intersection on Silverado Trail and a new streetlight. Silverado Trail at the Strawberry Patch: Improvements include widening the northbound travel lane on Silverado Trail in front of the Napa Strawberry business located at 2149 Silverado Trail (Strawberry Patch) to provide room for a left-turn lane and acceleration lane.
