Bonner Bridge – Innovation, Economy, and Durability in a Challenging Environment

摘要

The design-build replacement of the Herbert C. Bonner Bridge, which carries NC Highway 12 overOregon Inlet, required a 100-year service life, design for up to 84’ of scour, and minimal environmental impacts.The associated design and construction challenges provided opportunities for innovation and creativity. Theresulting 2.8 mile long bridge features extensive use of precast concrete for quality, durability, economy, andconstructability, a first-of-its-kind driven pile foundation verification method, and innovative, environmentallysensitiveconstruction approaches.
