Yale-Kilgore Road

Project Description  

Yale-Kilgore Road is located in Clark and Freemont Counties, ID and provides access to Caribou-Targhee National Forest.  The forest provides numerous activities for recreationists including access to hiking, biking, off road and snow mobile trails, along with other activities such as hunting and fishing.  This project proposes to improve two connected segments of Forest Highway ID-65 and STC 6805 (Yale-Kilgore Road) divided between Clark and Fremont Counties in Eastern Idaho.  The goal of this project is to enhance safety along the route and to meet public and commercial needs to expanded transportation in the area.  The total length of the combined project is approximately 21.8 miles.  The project will also feature a new, separated 3.7-mile trail for all-terrain vehicle (ATV) and snowmobile traffic through a heavily traveled area parallel to the road in Fremont County.

  • Caribou-Targhee National Forest (CTNF)
  • Federal Highway Administration – Western Federal Lands Highway Division (FHWA-WFLHD)


Scope of Work

The project scope for the Clark County segment (milepost (MP) 9.0 to MP 16.9) is to rehabilitate and pave 7.9 miles of gravel roadway to the Clark/Fremont County line. Additional roadway improvements include the replacement of culverts and other minor drainage improvements, widening the existing roadway, fixing soft spots, adding additional base, and paving the roadway. The intent of the project is to provide a consistent roadway width and to slightly widen the existing road beyond the current width of 22’‐26’.

The Fremont County segment of the project will consist of constructing a 27-foot wide, 3” thick asphalt overlay on a pulverized base, with sight distance and clear zone improvements, approach improvements, two (2) large culvert installations, and shoulder improvements. This portion of the project will also include the design of a separated trail running parallel to the road for ATV and snowmobile traffic for 3.7 miles, from the Shotgun area to Highway 20 (MP 26.55 to MP 30.25). The trial design will provide for a 10‐foot wide graveled surface travelway and 16‐feet of clearing to accommodate a snow grooming machine.
