Summary of Bridge Construction Plans – Loves Falls Trail, Pacific Crest Trail

This document is a set of structural and architectural drawings for a bridge construction project on the Pacific Crest Trail at Loves Falls, located in Tahoe National Forest, California. The project is managed by the U.S. Department of Agriculture Forest Service. The bridge design specifications reference AASHTO (American Association of State Highway and Transportation Officials) standards for highway bridges, with modifications for pedestrian and equestrian use, and incorporates specifications from the 1977 Roadway and Bridge Construction Standards.

The bridge structure includes the following key specifications and components: a 125-pound-per-square-foot live load capacity with snow and wind loads; air-entrained Portland cement concrete (vibrated, Class A, with 3,000 psi compressive strength at 28 days); reinforcing steel per ASTM A615 Grade 60; and structural steel per ASTM A500 Grade B for all tube sections and associated components. The estimate of quantities includes excavation for structures (1,545 cubic yards), structural concrete Class A (5 cubic yards), reinforcing steel (100 pounds), corrugated steel decking (1 job), and treated timber (1 job). The drawings detail the plan and elevation views, foundation design, arch rib connections, erection details, decking specifications, railing configurations, and railpost connection details. All steel members and components are specified for painting per Forest Service Standard Specifications, with construction quality requirements including radiographic inspection and complete shop assembly prior to field shipping.
