The Emlenton Bridge is a steel-deck truss bridge that spans the Allegheny River just south of the town of Emlenton, Pennsylvania, United States at approximately mile marker 44.4 on I-80.

This record was held until 1971 with the opening of the Fred G. Redmon Bridge near Selah, Washington.

The contractor of record is Brodhead Construction located in Aliquippa, Pennsylvania.

[1] The Emlenton Bridge is actually located in three different Pennsylvania counties due to its size and the geography of the land.
