NEW VIRGINIA SPAN IS BUILT LIKE A 5,000-TON WATCH

This article details the construction of a 5,000 ton steel and concrete bridge in southern Virginia. The bascule bridge features an overhead counterweight design, with a hydraulically-driven, rolling thru-truss that opens when pistons push up the outboard ends of the leaves. Teeth on the curved girders on the back corners of the leaves engage with teeth on the stationary tracks, thus walking the leaves back 6 feet as the tips rise up into the air. The overhead counterweight design efficiently shifts the load as the bridge opens, thus reducing wear on this bridge which spans the busy Atlantic Intracoastal Waterway.
