The Cape Fear Memorial Lift Bridge is a 3,033-ft four-lane highway bridge featuring a 408-ft lift span that provides 135 feet of vertical clearance above the navigation channel when in the raised position. As part of a Structures Management Unit On-Call Contract, the North Carolina Department of Transportation (NCDOT) tasked Modjeski and Masters (M&M) to perform a comprehensive rehabilitation of the lift span and its fixed approach spans to address defects identified regularly during routine bridge inspections, and to generally upgrade the facility. M&M provided project management along with final structural, mechanical, and electrical design services. Specific services included: structural steel repairs on lift span and fixed approach steel spans; replacement of open grid deck on lift span; replacement of median barrier; structural repairs on fixed approach span girders, deck, and abutments; replacement of deck joints on the fixed approach spans; various mechanical and electrical equipment upgrades; and other services. This latest project continues M&M’s history of working on this bridge which has included a comprehensive electrical system rehabilitation, inspections, and gusset plate analysis. M&M also provided engineering support services during the construction phase of the project.
