The GRS Bridges of Defiance County

This article describes a newly implemented type of geosynthetical-reinforced soil (GRS) integrated bridge system as tested jointly by the Federal Highway Administration (FHWA) and the local government of Defiance County, Ohio, in constructing the Bowman Road Bridge. GRS uses layers of polymeric geosynthetic materials that are reinforced and attached to facing elements of the outer wall of the system on which it is to be implemented. In this project, the system allowed for a very rapid construction of the bridge, taking 6 weeks instead of the months it might have taken had a conventional, cast-in-place concrete system been used. Because of the success of the Bowman Road Bridge project, Defiance County officials initiated 10 more bridge projects using GRS. All bridges were designed to withstand flood conditions that occur with frequency in the area.
