State Route 160
S.R. 160 Phase 1 Widening Project: A $16.5 million, 5-mile widening project between Mile Markers 11 and 16 broke ground in February 2016. It expands the highway from two to four travel lanes while flattening the side slopes for a partially divided asphalt highway that will be significantly smoother, allowing motorists to safely pass slower vehicles. The project is scheduled for completion in the summer of 2017. The project construction will be designed to safely accommodate road users with minimal delays. Final surfacing, signs, and striping will take place in spring of 2017, and be complete by mid-June.A traffic signal will be installed at the intersection of S.R. 160 and S.R. 159 during the summer, and the completion is estimated by the end of July.
S.R.160 Phase 2 Widening Project: NDOT is planning to widen a 6-mile stretch of Blue Diamond Road (State Route 160) from Mile Maker 16.3 to Mile Marker 22 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.
