As a 1951 structure, this bridge is a very early, and very large, example of limited-access highway bridge construction, and was built before the Interstate System came into existence. As such, it is representative of pre-interstate freeway design.
The photos of this bridge were taken from the north bank of the river, and actually show the smaller spans of the main part of the bridge. A larger navigation channel span is obscured by an island present at this location.
This bridge is next to an impressive railroad bridge.
Pennsylvania has decided to do what it has been doing with nearly every old bridge on the Allegheny River it has a say over, which is to demolish the bridge, ignoring any potential for cost, material, and history saving rehabilitation. In 2001, the National Bridge Inventory gave a 63.5% sufficiency rating, which is indicative of a structure for which rehabilitation rather than demolition should be considered. Given the other historic bridges on the Allegheny River that are far older, rarer, historic, and beautiful that Pennsylvania has wiped off the face of the earth, the demolition of this bridge perhaps seems almost insignificant. However, it is one more attractive bridge that has been lost to Pennsylvania's apparent quest to rid the Allegheny River of all bridges with historic value.
