  • Wildlife underpass 
  • Wildlife overpass 
  • 8-foot-tall exclusion fence along both sides of US 160
  • Earthen escape ramps and deer guards

  • Pavement resurfacing along a two mile stretch of US 160


pre-cast concrete forms set into place over the roadway

This past week's full overnight closures on US 160 resulted in the placement of 25 pre-cast concrete forms set into place over the roadway. This structure will become a big game wildlife crossing once completed later this year.

Work Schedule

  • Daytime work hours will be from 7 a.m. to 7 p.m., Monday through Friday.
  • The project is expected to last into late fall. 

Traffic Impacts

  •  A temporary signal will be installed to facilitate the completion of phase one of the underpass, reducing vehicles to a single-lane and alternating traffic intermittently in either direction.
  • Fifteen-minute delays are expected.
  • Speeds will be reduced to 30 mph in the work zone.
  • Advance public notice will be given for night work to take place for the construction of the overpass requiring a full shutdown of US 160 for approximately five nights. Alternate routes are advised.
