History
The original structure was built as a steel girder bridge with concrete piers. The steel was provided from a plant operated by Bethlehem Steel, directly adjacent to the turnpike in Steelton, Pennsylvania. It was opened to traffic in 1950.
On November 16, 2004, the Turnpike Commission let a contract for a bridge to replace the 1950 span. Two new 3-lane segmental, concrete signature spans were constructed just upriver from the old 4 lane span. The new span was the first of its type built in Pennsylvania at a cost of nearly $100 million [1]. The westbound span opened on 17 May 2007, and the eastbound span was opened on 17 June 2007. The new roadway and bridges opened to normal traffic flow in the summer of 2008. The old span was demolished on August 22, 2007.
