Lesner Bridge Replacement Lynnhaven Inlet

Owner:
City of Virginia Beach
Location:
Virginia Beach, VA

This $78.8M project was for the replacement of the existing Lesner Bridges over the Lynnhaven Inlet in Virginia Beach, Virginia with a signature facility capable of handling six lanes of traffic. This project featured twin 1,575-foot-long precast concrete segmental bridges with drilled shaft foundations. Each structure consists of (9) 150-foot approach spans that were constructed utilizing span-by-span construction techniques with an overhead gantry. The 225-foot main span features a progressive cantilever design constructed with the same overhead gantry system. This project was completed in an environmentally sensitive area subject to extreme tidal flows. The second bridge structure was constructed adjacent to an overhead transmission line. The combination of the tidal and wind effects and the close proximity of the overhead transmission line on the construction access and techniques made for a very challenging project that demanded precise planning and execution. The bridges were constructed over a major navigable channel with continuous boat traffic from the Virginia Pilots Association, commercial and private fishing vessels, and pleasure boats. The new bridges now provide a minimum 45-foot vertical clearance above mean high water and a 150-foot minimum horizontal clearance at the center navigational span.
