Rehabilitation of the 105 year old Mulberry Street Bridge; Harrisburg’s First Major Concrete Highway Bridge

摘要

Mulberry Street Bridge crosses Paxton Creek, Amtrak, Norfolk Southern Railroad, 10th Street, and Cameron Street, adjacent to Amtrak’s Harrisburg Station. The 18-span, 1,598 foot long, reinforced-concrete arch bridge was the first major highway bridge in Harrisburg. The inspection, structural analysis, and material testing concluded that a major rehabilitation was required, 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 character defining features of this historic structure.
