The Mears Memorial Bridge is a truss bridge of the Alaska Railroad, completed in 1923. The bridge spans the Tanana River at Nenana and at 700-foot-long (210 m), it is among the largest simple truss-type bridges in the world.
The bridge was the final link in the railroad, entering service in February 1923, a year after the rest of the 470 miles (760 km) line was finished. The AEC hired the Chicago firm of Ralph Modjeski and Angier to design the bridge, and the American Bridge Company to fabricate and erect it. When completed, this 700-foot-long (210 m) Pennsylvania through-truss bridge was the longest truss span in the United States and its territories.
This bridge still ranks as the longest span of any kind in Alaska and the third-longest simple truss bridge in North America. The Juneau-Douglas Bridge main span across Gastineau Channel at Juneau ranks second at 620 feet (190 m).
