The 18-span, 1,598 foot long,reinforced-concrete arch bridge was the first major highway bridge in Harrisburg. Theinspection, structural analysis, and material testing concluded that a major rehabilitation wasrequired, including a new concrete deck, selective member replacement, new strip seal dams,railing, and lighting. It was key that the rehabilitation would not adversely affect the characterdefining features of this historic structure.
