The Varina-Enon Bridge features the world's first use of precast concrete delta frames for construction of its 630' cable-stayed main span. This cost effective and innovative structure carries six lanes of I-295 over the James River. All seven bidders chose the precast concrete segmental design over the competing steel design, saving the Virginia Department of Transportation approximately $10 million over their project estimate. On August 6, 1993, the bridge withstood a direct tornado strike across the center of its main span without any damage, although the tornado overturned trucks traveling on the bridge.
