State Route 160
NDOT completed its $16.5 million widening project on State Route 160, commonly known as Blue Diamond Road, between Red Rock Canyon and Mile Marker 17 on May 31, 2017. The five-mile endeavor included expanding the highway from two to four lanes, adding an additional passing lane in each direction for a safer and smoother ride. Some side slopes were flattened enabling motorists to safely pull off to the side of the road.
In a separate project, new traffic control signals were added at the intersections of Fort Apache and El Capitan roads, along with new pedestrian crosswalks.
Phase 2 of the widening project will target a six-mile stretch of S.R. 160 from Mile Marker 16.3 to Mile Marker 22. This project will expand the highway from two to four lanes in Clark County. Plans call for a raised median barrier, bicycle lanes, and flattened side slopes for safe turnouts as well as new signage and improved intersection lighting. Other proposed enhancements entail frontage roads for the Mountain Springs community, an emergency signal at the Volunteer Fire Station, and a wildlife undercrossing near Mile Marker 18.4. CA Group is doing the initial design, engineering and environmental. Construction is scheduled to begin in 2018.
