The West Virginia Division of Highways is building the new 58-foot Fourteen Mile Bridge along Lincoln County Road 37 near Ranger using a technology that hasn’t been used in the state before, the TimesUnion reports.
The new bridge is being built using a press-brake-formed steel tub girder (PBTG) bridge, which consists of galvanized shallow trapezoidal boxes built from cold-bent structural steel plate. The concrete deck is precast on the girder, and then trucked to the project site. Designers from West Virginia University and Marshall University are helping with the project.
The $2.2 million bridge contract went to Orders Construction Co. Work is expected to be completed by November 15.
