About this file

Written by GovTribe AI · Aug 2, 2024

This document is a set of standard drawings for a 41-ft glulam stringer pedestrian trail bridge to be constructed on the Bitterroot National Forest. The drawings provide details on the bridge design, including stringer sizes, deck and railing construction, and abutment details. Key specifications include a 41-ft bridge span, 20F-V13 glulam stringers, and a 7-ft clear width. The drawings also include general notes on material requirements, treatment, fabrication, and installation. This is one of the technical documents associated with the Bitterroot National Forest - Little Rock Creek Trail Bridge Replacement solicitation, which has an estimated construction value between $100,000 and $250,000. The project involves removing an existing 35-ft single log foot bridge and installing the new glulam stringer bridge, with work to be completed between September 15 and November 14, 2025.
