Abstract:

The replacement of the US Grant Bridge over the Ohio River in Portsmouth, OH, was initiated in

2001 when the original bridge was closed and demolished, and its substitute opened in 2006. The

new design is a steel cable stay design with steel girders and floor-beams supporting a posttensioned concrete deck system nearly 65’ wide carrying one lane of traffic in each direction. The

combination of epoxy-coating, grout filling, and outer tubing provides protection for the all-important

structural cabling suspension system from both weather and corrosion. Ironically, however, these

same features make it impossible to gain direct access to either the cables or the interior of the

anchorages which, in turn, presents special challenges for inspection and rehabilitation of these

critical bridge components on bridges of this type. It was envisioned that its long-term behavior and

any associated changes in its structural condition could be best understood with the aid of a

longitudinal study beginning during bridge construction, one that includes instrumented monitoring of

both construction/erection and in-service phases of the life of this bridge. Such an approach,

integrated with traditional bridge management techniques, would help lead to a safe and economical

realization of the 100-year design life of this structure. A health monitoring system for the bridge

would be designed, planned, and implemented, with data collection and archival throughout its

construction and ultimately an automated, user-friendly interface on a dedicated website.
