• Description:
  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.
