Overview
A one mile passing lane will be added for northbound drivers just before they travel down the Winchester grade at milepost 278 in Lewis County. In addition to the passing lane construction, a northbound acceleration lane will be constructed for traffic entering the highway from the rest area. This will be accomplished by performing soil cuts, fills, culvert work, and approach reconstruction in support of the passing lane design.
The goal of this project is to reduce the northbound traffic congestion descending Culdesac Canyon on US-95 and reduce traffic delays.
Construction is currently scheduled for 2029.
