2L Trail Highway 93 Trail

Project Description

The proposed project will build an approximately five mile trail long from Kids Creek Park to the Bureau of Land Management’s (BLM) Shoup Recreation Site, a popular launch site for anglers and rafters. The purpose of this project is to build a paved trail for pedestrian and bicycle traffic, moving it away from the narrow shoulder of Highway 93. This will improve safety for both vehicular and non-vehicular traffic.   The project will also include improvements to the campground at Shoup Bridge.

Project Partners

  • Lemhi County
  • Salmon Valley Stewardship
  • Idaho Department of Transportation
  • Bureau of Land Management
  • Federal Highway Administration – Western Federal Lands – Highway Division

Scope of Work

The trail will start at Kids Creek Park and cross State Highway 93 at the Union Lane intersection, within a thirty-five miles per hour zone. The trail will remain within the existing western easement of the highway and continue south to the Shoup Bridge Recreation Site. The west side of the highway was selected with public input since it is commonly used for non-vehicular traffic and there is a large irrigation channel/ditch within the eastern easement. 

The trail will cross approximately forty to forty-five property approaches and four road intersections. The existing approaches will be a controlling feature of the trail design and the trail will adjust its alignment and grade as it crosses these approaches and intersections.  Underground utilities which exist within the right-of-way will be considered in the trail design and be relocated as necessary during construction.  Other infrastructure such as road signs and private mail boxes will be considered in the trail design. Consideration will also be given to the turning lanes at the Airport Road and Williams Creek Road intersections.  Design of both intersections will consider the narrowness of the right-of-way and the closeness of the highway speed traffic to provide the safest possible option for all users.
