The New Shenandoah River Bridge - WV9
« Back to Featured Projects
Jefferson County, West Virginia
This Design-Build project, awarded to Trumbull Corporation and HDR Engineering on January 5, 2010, aimed to create a new bridge over the Shenandoah River in Jefferson County, West Virginia. The project's stretch of roadway is a portion of the recently upgraded WV Route 9, a partially controlled access four-lane divided highway, which extends from the Charles Town Bypass on US 340 to the West Virginia and Virginia state line. 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 Shenandoah River Bridge project received the 2013 Engineering Excellence Award from ACEC WV.
