Chesapeake Utilities was expanding in the 1980s, and needed to bring in more capacity. Gas fields were located nearby in western Pennsylvania, so a pipeline coming in from the north and crossing the C&D Canal seemed to make the most sense. They engaged Clear Span Engineering from Houston, Texas, to design the new canal crossing. What emerged was a pure suspension bridge that would suspend the 12-inch pipeline 141 feet above the water. Clear Span was ideally suited to complete the design given that pipeline bridges was their specialty. They have designed over 100 pipeline bridges. The Trinity Steel Company, also from Texas, was hired to fabricate the steel for the structure. The pipeline bridge was completed in 1986.
I am not aware of a formal name for this bridge. The US Army Corps of Engineers maps simply refer to it as the Pipeline Bridge. That is a little generic, so I am calling it the Eastern Shore Pipeline Bridge.
The photo above is looking to the east towards the pipeline bridge as seen from the north shore of the C&D Canal. The Conrail Bridge, a large railroad lift bridge, is visible just over a mile further to the east.
