Stoddard Bridge

Project Description

Stoddard Pack Bridge is a pedestrian and pack animal crossing over the Salmon River, approximately 0.5 miles downstream of the confluence with the Middle Fork of the Salmon River. The bridge is an important access point into the Frank Church River of No Return Wilderness Area. The original 348-foot wooden suspension bridge was replaced in 2014 utilizing the original suspension cables. The replacement bridge collapsed in March 2017 due to rockfall damaging the 35-foot tall south side suspension tower. A new asymmetric suspension bridge is proposed to replace the damaged bridge and will have the same deck widths of the previous bridge.

Project Partners

  • United States Forest Service (USFS) – Salmon-Challis National Forest
  • Federal Highway Administration – Western Federal Lands

Scope of Work

This project will reconstruct the wooden pack bridge that was destroyed by a rockfall event in March of 2017. The new, proposed asymmetric suspension bridge will be constructed near the site of the previous bridge, but the south tower will move west to avoid higher-risk rockfall potential. The existing north tower will be reconstructed at the same location.
