Couple of lines for a question depending on the length

Adding a passing lane will provide drivers a safer opportunity to pass, while also improving capacity and mobility.

As part of a larger project to construct a passing lane from Winchester to Culdesac, work will start on the second phase this spring to add 2.5 more miles of a passing lane. Nine culverts will also be replaced in this phase, which will take two years to construct. During most construction activities, one 11-foot-wide lane will be open in each direction. However, during rock blasting and cleanup, the highway will be completely closed for one to two hours at a time; these activities will not be scheduled over holidays or during peak travel times.

Construction overview

Project
Updates

Although most complete closures of US-95 will be scheduled at night, during the second week of April, traffic will be stopped in both directions to allow the construction of an equipment access trail above the rock slope. Rock and other debris will be pushed off the slope into a catchment area for cleanup. Drivers should expect delays of at least 15 minutes; if rock falls onto the road, delays could become longer as crews remove it.
