This is a Construction/Reconstruction Plans document for specified roads issued by the U.S. Department of Agriculture Forest Service, Northern Region, for the Bitterroot National Forest, Darby Ranger District in Ravalli County, Montana.

The project, titled "Bitterroot Front IRSC - Hart Trap," involves reconstruction and maintenance of multiple forest roads spanning approximately 40.23 miles across 19 individual road segments (including roads 374A, 5626, 5627, 5634, 13204, 13226, 13226.1, 13276, 13278, 62413, 62872, 62873, 62874, 62882, 62887, 62888, 62908, 74972, and 74996). The work includes roadway reconditioning with various configurations (crown, outslope, inslope, and ditch), roadside clearing with 5-foot outer limits, road construction with specified cut and fill slopes, curve widening on horizontal curves, culvert installation (primarily 18-inch diameter pipes), turnouts, turnarounds, and drain dips. Materials and construction shall comply with the Standard Specification for Construction of Roads and Bridges on Federal Highway Projects (FP 14) and applicable Forest Service Special Specifications. The contractor is responsible for maintaining haul routes, dust control, traffic control, soil erosion and sediment control, dewatering, and material disposal at designated waste sites. The plans include detailed drawings showing typical sections, drainage details, cross-slope requirements, riprap specifications, and comprehensive worklists with specific pay items and quantities for each road segment. Design was completed November 18, 2025, with project approval dated December 14, 2025.
