The Luzerne County engineer chose to rehabilitate this historic bridge, finding that they could do so for far less than the cost of constructing an ugly 2 lane modern bridge. This is often the case with historic truss bridges, but is often a fact overlooked. Fortunately, due to the success of this bridge rehabilitation, the county is looking into rehabilitating more county historic bridges. An excellent preservation success story.
