Trumbull and HDR Engineering provided design-build services for the creation of a new bridge over the Shenandoah River in Jefferson County, West Virginia. The project included the approaches to the bridge, which carries West Virginia Route 9 between County Route 27 and County Route 32/2, a distance of approximately 1,805 feet.
The Delta-Rahmen Bridge stretches 1,650 feet across the Shenandoah River Valley, carrying the highway 200 feet above the river below. The substructure consists of two abutments and four piers, utilizing 560,000 pounds of reinforcing steel, 7,700 cubic yards of concrete and 43,000 square feet of formwork. The second abutment also required the construction of a 200-foot long, 45-foot tall MSE wall. The superstructure of the bridge contains nearly 13 million pounds of structural steel and utilizes a 5-girder, 4-substringer system supported by five lines of Delta Legs. A Conspan bridge system was used on one side of the bridge to eliminate an additional span on the main bridge structure. This Conspan bridge is 105 feet long, 24 feet wide, and 20 feet tall, with the heaviest piece weighing 52,000 pounds.
The project received the 2013 Engineering Excellence Award from ACEC.
