NAPA, Calif. – Beginning June 22 and continuing for three weeks, Martin Brothers Construction will begin construction of the Silverado Trail overlay project.

The project limits are from Calistoga to Larkmead Lane.

Construction will be scheduled 7 a.m. to 5 p.m., Monday through Friday. Motorists should expect 15-minute delays. Avoid the area if possible.

Detours include Highway 29, using Tubbs Lane to the north, and Deer Park Road to the south in order to cross the valley.

Depending on the location of the work on any given day, other crossroads from Silverado Trail to Highway 29 may be available.

An overlay is the placement of a two-inch thick layer of brand new pavement over the existing road surface.

The contractor will perform some repairs of the existing roadway first to ensure the maximum longevity of the new pavement.

Once completed, it will restore the road condition, with a smooth, quiet ride and greatly extend the life of the road.
