Susitna River Bridge

The Susitna River Bridge spans 503 feet across the water with a steel through-truss design incorporating two combination Howe truss flanking sections.

The American Bridge Company constructed this railway crossing between 1920 and 1921, establishing a crucial connection point for the United States Government Railway in Alaska.

The bridge earned recognition on the National Register of Historic Places in 1977 for its engineering methods and role in Alaskan transportation development.

Located 150 miles north of Anchorage at coordinates 62.767778, -149.693611, the bridge continues to serve the Alaska Railroad Corporation for regular rail transport.

The construction teams used heated sand and gravel during the concrete pouring process to overcome the freezing temperatures that complicated the building operations.
