The Susitna River Bridge, also known as the Gold Creek Bridge, was the longest bridge span on the United States Government Railway in Alaska. The steel 504-foot (154 m) through-truss channel spans the Susitna River. It was completed in February, 1921. The crossing of the Susitna includes two 121-ft. combination Howe truss flanking spans and two 70-foot (21 m) combination pony Howe truss end spans, with 392 feet (119 m) of trestle at the southern approach and 28 feet (8.5 m). at the northern approach, making a total length of 1,322-foot (403 m). It is located 150 miles (240 km) north of Anchorage, and 264 miles (425 km) north of the terminus at Seward. The bridge was listed on the National Register of Historic Places in 1977.
