Early Monday morning, a section of Silverado Trail was damaged in a storm-related washout, resulting in a closure at Madrone Knoll Way to Meadowood Lane near St. Helena. Efforts are underway to reopen this section of Silverado Trail as soon as possible. The County expects repair work will begin as early as Friday and anticipates that Silverado Trail will be reopened within the next three weeks. Pavement will be removed, all loose soil will be excavated, a new base, consisting of large rocks (which will help with drainage) and soil will be replaced, and the road will repaved, striped, and guardrails replaced around the impacted area.
Northbound Silverado Trail vehicles should continue to detour via Zinfandel to Highway 29 northbound. Southbound Silverado Trail vehicles should continue to use Deer Park Road to Highway 29 southbound.
Today the County is installing temporary signals at Deer Park Road and Highway 29 to assist southbound drivers making the left turn from Deer Park to SR 29 and improve traffic control on the detour route. The signals will be installed between 4-5 pm today, Wednesday, October 27, which was the earliest time that signals could be delivered and set up. The County will seek to minimize disruption during this time. Drivers should expect changed conditions.
