[Ferro-Alloys.com] The Short Span Steel Bridge Alliance (SSSBA) is working with the West Virginia Division of Highways (WVDOH) to construct a press-brake-formed steel tub girder bridge, the first one in the state to demonstrate this innovative technology.

Girder erection for the 58-foot span Fourteen Mile Bridge in Lincoln County (District 2) near East Lynn is scheduled to begin on August 20, 2019. The contractor is ORDERS Construction Company based in Saint Albans, WV. The project is scheduled for completion in November 2019. A second press-brake-formed steel tub girder (PBTG) bridge project is expected to be constructed in District 4 (on US 250 over Flat Run near Mannington, WV) in 2020.

The press-brake-formed tub girder system consists of galvanized shallow trapezoidal boxes fabricated from cold-bent structural steel plate. A concrete deck is precast on the girder, making it a modular unit that can be transported by truck to the project site. The PBTG system is ideal for spans up to 60 feet. It saves time and costs for bridge owners since it can be installed as a single modular unit usually in one or two days by local crews, will last for an estimated 100 years, and requires minimal maintenance during its lifetime. The expedited installation process ensures the new bridge is opened for service in a timely manner, minimizing disruption to traffic. (BuildUsingSteel)
