Princeton Road Bridge Replacement

This bridge replacement project required unique design and collaboration to not only address the deteriorated bridge, but to also accommodate a roundabout located immediately adjacent to the bridge’s rear abutment. The bridge design involved the replacement of a 3-span continuous steel beam structure with a 128-foot single span, composite, prestressed I-beam bridge with flared geometry. To accommodate the adjacent roundabout, the bridge was shifted 20 feet to the east from the existing location, and it was constructed variable width. The bridge was built through a county-let contract, and the roundabout was built simultaneously under a separate Ohio DOT-let contract. Combined, these projects improved congestion and safety by replacing a deteriorated bridge and upgrading the adjacent intersection from a T-type intersection to a roundabout.
