O'Shaughnessy Dam Bridge Replacement Project
City of Columbus Department of Public Works
1989 – 1993
This challenging project included complete removal and replacement of a concrete bridge carrying traffic across the existing O’Shaughnessy Dam. The work included demolition of the existing structure, construction of new piers on top of the existing dam spillway, and construction of a box beam superstructure with a composite concrete deck and architectural precast concrete railings to replicate the original structure.
