With the Hunter Station Bridge now gone, only six half-through truss bridges exist in the US, 10 worldwide. Construction started last year and traffic shifted onto the new bridge in July, when it was completed to traffic. The structure was listed as eligible for the National Register of Historic Places, but it was not enough for the it to be saved, for years of neglect with rusted trusses and damages to concrete and steel railings led to PennDOT to replace the structure with the new span.
The roadway is wedged between the riveted trusses, even though a sidewalk existed on one side. The strut bracings are all X-laced and uncovered. Cox Construction Company featured a 30° skewed overhead chord with X-laced portal bracings encased in a C-beam form that can be seen as a beam portal upon entering the bridge. The 1050-foot Long span was built in 1934 by P.I. The Hunter Station Bridge, a three-span Pratt half-through truss Bridge spanning the Allegheny River at US Highway 62 between Oil City and Lighthouse Island in Forrest County was dropped with explosives last week, two months after ist replacement span was open to traffic. Since October 4th of the year, that number has been reduced to one.

This means the truss can be seen both when driving by car on the road or boating underneath. This consists of a truss bridge, whose roadway is wedged right in the middle of the truss itself. OIL CITY, PA- Between through truss bridges which have an overhead chord and a deck truss, where the trusses are underneath the roadway, we have the half-through truss design.
