Contractors are replacing signage and guardrails on US-95 near Winchester in preparation for extending the passing lane in the canyon by about three miles.
The speed limit has been reduced but one lane in each direction will typically be open during the day.
In late April or early May, workers will start to remove rock, which will require some evening blasting. The work will require US-95 to be closed for approximately one hour around 6 p.m.
“Closures will not be scheduled over the holidays and will generally be timed to avoid peak travel,” resident engineer Curtis Arnzen said. “Rock removal will be necessary for the duration of this project, and we strongly encourage drivers to plan around these closures if possible as there will be no detour in place.”
