About this file

Written by GovTribe AI ·

This is a Work Items specification document for the Sweet Trunk Trail #274 construction project on the Custer Gallatin National Forest. The project spans approximately 97,153 linear feet from the trailhead parking near Half Moon campground at the end of Big Timber Canyon (station 0+00) to an intersection with an existing trail (station 971+53).

The primary work activities include: clearing and maintaining 18.41 miles of trail; constructing 96,153 linear feet of new stock trail with clearing, grubbing, and unclassified excavation; constructing 1,000 linear feet of new stock trail within rock requiring blasting or hammering; installing 100 drain dips with leadoff ditches; constructing 25 six-foot radius switchbacks with maximum 8% grades and 50-foot approaches; installing a 72-inch steel pipe swing gate with H-braces and posts at the trailhead; constructing 15 sediment trap ditches across a steep CAT trail; constructing two rock retainer turnpikes (15 linear feet and 30 linear feet); installing one 15-inch by 15-foot PE culvert with outlet ditch; and installing approximately 35 posts at various locations including property boundaries, trail intersections, and scenic overlooks. The work also encompasses natural fords and stream crossings where no construction is required. All work items are tied to specific drawing numbers, specifications, and pay items for cost accounting and quality control purposes.
