S.R. 160 Widening Project Enters Second Work Phase in Clark County

Post Date:02/01/2019 2:33 PM

CLARK COUNTY, NEV. – The Nevada Department of Transportation (NDOT) last month began work on the second phase of a $58.6 million State Route 160 upgrade project that includes, among other things, rehabilitating 22 miles of deteriorating roadway from roughly the Nye County line to the Mountain Springs community in Clark County. Aggregate Industries SWR Inc. is the general contractor.

The project calls for revamping the eastbound travel lanes, placing a cement-treated road base with an asphalt pavement overlay. These improvements will ensure roadway integrity and durability while creating a smoother, safer driving experience for motorists. As such, State Route 160 will be reduced to one lane in in each direction separated by barrier rail through the work zone, with travel speeds reduced to 55-mph. Additionally, a temporary stop signal has been placed at Tecopa Road for safe highway access through late-April. However, all 22 miles of roadway enhancements won’t finish until November.

Meanwhile, work continues along a 6-mile-long highway widening, from two to four travel lanes, between Mile Markers 16 and 22, with intermittent construction blasting occurring through year’s end to remove fractured bedrock. 

Blasting will result in temporary highway closures lasting up to 120 minutes, while crews place explosives, check the blast area and clear away rubble and debris. Check the department website at: for the most recent blasting schedule. 

The project, which began in the summer of 2018, additionally calls for installing new signage and flattening side slopes for safer turnouts, as well as placing new cattleguards and a wildlife undercrossing near Mile Marker 18. The Mountain Springs Community, meanwhile, will receive new frontage roads, improved intersection lighting and an emergency signal for Clark County Volunteer Fire Station #79. Total project completion is scheduled for August 2020.

Motorists should use caution while travelling through the work zone, heed construction signage, and take alternate detour routes, if possible. NDOT works with Waze to inform the public about planned highway restrictions, but unscheduled construction changes, closures and restrictions are possible due to weather or other factors.
