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 for students and other commuters.
