Geosynthetic Reinforced Soil - Integrated Bridge System
USDA Forest Service - The Layout Creek Bridge Project is an aquatic restoration project that seeks to return the current undersized culvert crossing to a more natural state by replacing the culvert with a bridge that has already been designed with prior investment from the Forest Service and Bonneville Power Administration. The substructure was designed using a Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS) design, while the superstructure was designed with prefabricated prestressed concrete beams, both of which are promoted under FHWA’s EDC initiative. Additional funding from other sources is being used for fabrication and a portion of the construction, while the AID Demonstration funding will be used for the GRS-IBS construction portion of the project. It is the intent of the Forest Service to use this project to accelerate the use of GRS-IBS structures technology on other national forests, particularly in combination with a prefabricated superstructure as in this case, by demonstrating the many benefits including time savings, cost savings, flexible design, increased constructability, safety advantages, and reduced environmental impact.

The Catwalk National Recreation Trail in New Mexico’s Gila National Forest reopened to visitors in time for the 2016 summer season. Design-build project delivery helped accelerate reconstruction of the pedestrian catwalk, damaged in 2013 flooding. The recreation area draws thousands of visitors annually and is an important economic generator for nearby communities. The project received funds from the Emergency Relief for Federally Owned Roads program.
Geosynthetic Reinforced Soil - Integrated Bridge System
The U.S. Forest Service restored Layout Creek in Washington’s Gifford Pinchot National Forest with a grant from FHWA’s Accelerated Innovation Deployment Demonstration program. The aquatic restoration project returned the undersized culvert crossing to a more natural state by replacing the culvert with a bridge. The project used geosynthetic reinforced soil integrated bridge system design for the substructure and prefabricated prestressed concrete beams for the superstructure. GRS-IBS was also used to build the Sand Creek Bridge in Dawes County, Nebraska, which accesses the Oglala National Grasslands. The project took just 15 10-hour work days to complete.
