About this file
These are 95% design plans for the United States Department of Agriculture (USDA) Forest Service, specifically for replacing two trail bridges in the White Mountain National Forest's Androscoggin Ranger District in New Hampshire. The project involves replacing Huntington Ravine Trail Bridges #4 and #5 at milepost locations 0.1202 and 0.3312, respectively. The proposed bridges are single-span steel girder bridges with timber plank decks on steel grade beam foundations, with overall lengths of 30 feet and 24 feet. The bridges will be located along the Huntington Ravine Trail near the Appalachian National Scenic Trail, with construction requiring trail closure and helicopter transport of materials due to the remote mountainous location.
Key design details include using salvaged steel from the existing bridges for new foundations, implementing riprap and erosion control measures, and installing object markers and signage. The project specifications require in-stream work between June 1st and September 15th, with tree cutting permitted between November 15th and March 31st. The design follows AASHTO LRFD Bridge Design Specifications and USDA Forest Service transportation structure guidelines. Material specifications include galvanized steel, treated Southern Yellow Pine timber, and specific connection hardware, with a focus on minimizing environmental impact and maintaining trail accessibility for emergency and avalanche inspection operations.

ALL HARDWARE FOR TIMBER CONNECTIONS TO MEET ASTM A307-97 GALVANIZED TO F2329 (A153). ALL HIGH STRENGTH HARDWARE FOR DIAPHRAGM CONNECTIONS TO MEET
ASTM F3125 GRADE A325 TYPE 3 OR GRADE A449 GALVANIZED TO A153.
ALL BOLTED STEEL CONNECTIONS SHALL BE MADE WITH A325 TYPE III BOLTS.
IF GALVANIZED FASTENERS ARE CUT OR DAMAGED IN THE FIELD, THEY SHALL BE REPLACED OR TOUCHED UP WITH COLD GALVANIZING COMPOUND AT THE DISCRETION OF THE
FOREST SERVICE CONTRACTING OFFICER REPRESENTATIVE.
MATERIAL & FABRICATION NOTES:
SHOP DRAWINGS:
THE FABRICATOR SHALL BE RESPONSIBLE FOR THE PREPARATION OF SHOP DRAWINGS FOR THE TIMBER DECK, TIMBER CURB, STEEL BEAMS, AND STEEL DIAPHRAGMS IN
ACCORDANCE WITH THE STANDARD SPECIFICATIONS.
