About this file
This is a set of engineering design drawings for a trail bridge replacement project by the United States Department of Agriculture (USDA) Forest Service in the Daniel Boone National Forest, London Ranger District, Laurel County, Kentucky. The project involves removing an existing 24-foot wooden bridge and installing a new 24.5-foot treated sawn stringer timber bridge at the intersection of the Sheltowee Trace Section 26 and the Wintergreen Trail, while reusing the existing bridge foundations. The new bridge will be 4 feet wide, constructed with Southern Pine timber, and include a railing system. The design specifications include detailed requirements for timber grades, hardware, treatment, and installation, with particular attention to preserving the existing substructures and using native materials for approach reconstruction.

SPECIFICATIONS: MATERIALS AND CONSTRUCTION OF THIS STRUCTURE SHALL BE IN ACCORDANCE
WITH THE STANDARD SPECIFICATION FOR CONSTRUCTION OF ROADS AND BRIDGES ON FEDERAL
HIGHWAY PROJECTS (FP-03) AND STANDARD SPECIFICATIONS FOR CONSTRUCTION OF TRAILS AND
TRAIL BRIDGES ON FEDERAL PROJECTS,
CONCRETE: USE STRUCTURAL CONCRETE WITH 7 SACK MINIMUM MIX APPROVED BY THE C.O.,
CONCRETE SHALL RECEIVE A TOWELED SURFACE FINISH. CONCRETE SHALL HAVE 4%-6% ENTRAINED
AIR. MAXIMUM SIZE AGGREGATE SHALL BE 3/4-INCH AND CONCRETE SLUMP SHALL NOT EXCEED
4-INCHES.
REINFORCING STEEL: PROVIDE REINFORCING STEEL THAT CONFORMS TO ASTM A615 (AASHTO M31), GRADE 40 OR 60. PROVIDE 2-INCH CLEAR CONCRETE COVER FOR ALL REBAR, UNLESS NOTED
OTHERWISE ON THE PLANS.
HARDWARE AND STRUCTURAL STEEL: SEE SHEET 3 FOR PROJECT DESIGN CRITERIA AND GENERAL
NOTES.
TREATED TIMBER & LUMBER: REFER TO THE GENERAL NOTES ON THE SUBSTRUCTURE DRAWINGS FOR
TREATED TIMBER & LUMBER SPECIFICATIONS AND FIELD TREATING OF WOOD
LAG SCREW INSTALLATION: PRE-BORE LAG SCREW HOLES USING TWO DIAMETERS, ONE FOR THE
SHANK AND ONE FOR THE THREADS. THE LEAD HOLE FOR THE SHANK IS TO BE 1/16-INCH LARGER THAN
THE SHANK DIAMETER AND IS TO BE BORED TO THE DEPTH OF PENETRATION OF THE SHANK. THE LEAD
HOLE FOR THE THREADED PORTION IS TO BE 70% OF THE BOLT DIAMETER AS SHOWN ON THE PLANS
AND IS TO BE BORED AT LEAST TO THE LENGTH OF THE THREADS. DO NOT DRIVE LAG SCREWS WITH A
HAMMER.
