Work ongoing to extend passing lane on US-95 near Winchester

US-95 climbs through a green Culdesac Canyon.

Update from April 4: 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.

Speeds are now reduced on US-95 near Winchester as contractors replace signage and guardrail in advance of construction to extend the passing lane by three miles in the canyon.

For the next month, drivers can expect continued work on the shoulders as well as the creation of a trail for equipment to access the rock slope west of the highway. One lane in each direction will typically be open during the day, with work over the weekends possible throughout the season.

Once that work is completed around late April or early May, crews will start rock removal.

Rock removal will require some evening blasting and periodic closures of US-95. Closures will be scheduled around 6 p.m. and are expected to last approximately one hour, after which one lane of the highway may remain closed for cleanup.

“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.”

Closures will be advertised via digital message signs on the highway, 511 and updates on the project website.

Work this season is expected to end by November, with the entire project scheduled for completion in fall 2020. Construction in 2016 extended the passing lane in the area 1.5 miles, and future work will finish the passing lane between Winchester and Culdesac.
