The Emlenton Bridge is a steel deck truss bridge that spans the Allegheny River just south of the town of Emlenton, Pennsylvania at approximately mile marker 44.4 on I-80. With a height of 270 feet (82 m) above the river, the Emlenton Bridge was the highest bridge in the Interstate Highway System when completed in 1968 (The Lewiston-Queenston Bridge is higher but is technically an international bridge, not part of the Interstate Highway system). This record was held until 1971 with the opening of the Fred G. Redmon Bridge near Selah, Washington.
