Warren Wagon Road is located along the North Fork Payette River, north of McCall, ID. This road, which is owned and maintained by Valley County, was approved for FLAP funding in 2017 to improve safety and drainage, and minimize ongoing maintenance issues. The road is primarily used to access hiking, picnic sites, and other recreational opportunities along this scenic and historic corridor.

Key improvements to the roadway included construction of a frost-resistant pavement section, stabilization of shallow roadway embankment slides, reconstruction of a sharp curve and advance warning signs, replacement of obsolete guardrail, culvert design to improve drainage, and reconstruction of the road pavement section.

DJ&A completed project scoping, preliminary design, and final design for these improvements.
