Pomeroy-Mason Cable-Stayed Bridge

Pomeroy, Ohio

The Pomeroy-Mason Bridge is a concrete, cast-in-place cable-stayed bridge with distinctive delta-shaped towers that replaced an existing two-lane steel truss bridge on U.S. Route 33 over the Ohio River in Meigs County, Ohio. The cable-stayed portion of the bridge is more than 1,852-feet-long, with a 675-foot-wide main span and 244-foot end spans. This new bridge provides a link between two cities – Pomeroy, Ohio, and Mason, West Virginia.

Michael Baker served as an extension of construction staff to the Ohio Department of Transportation (ODOT). Our team provided construction support services and structural expertise on the bridge replacement project. Services included contract administration assistance, construction inspection and documentation, constructability reviews, schedule management and monitoring, bid tabulation reviews, submittal reviews and project closeout support.

Constantly evolving construction conditions throughout the duration of the project presented many challenges for the team to overcome, including two major floods, a significant slope stability issue on the Ohio side of the bridge, complicated falsework, rock slope remediation and foundation element redesign. There was also an urgent need to re-build the West Virginia tower after significant voids were discovered in the concrete. Through close collaboration and frequent communication among our team, ODOT and the contractor, the project was ultimately completed with no lost time injuries and an excellent overall safety record.
