Accelerated Innovation Deployment (AID) Demonstration Project: Gifford Pinchot National Forest Layout Creek Bridge Project

The Layout Creek Bridge Project was an aquatic restoration project that returned the previous undersized crossing to a more natural state by replacing a culvert that was constricting the channel with a larger and more open bridge structure. The substructure of the bridge consists of a Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS) design based on Federal Highway Administration (FHWA) GRS-IBS Interim Implementation Guide (FHWA-HRT-11-026), while the superstructure was designed of prefabricated prestressed concrete beams, both of which are promoted under FHWA’s Every Day Counts (EDC) initiative. The AID Demonstration funding was used to construct the GRS-IBS construction portion of the project while additional money from the Forest Service and partners was used to complete the bridge project. It is the intent of the Forest Service to use this project to evaluate and possibly accelerate the use of GRS-IBS structures technology on other national forests, particularly in combination with a prefabricated superstructure as in this case, by measuring the many potential benefits including time savings, cost savings, flexible design, increased constructability, safety advantages, and reduced environmental impact. This document serves as a working document to be used to facilitate the development and implementation of information collection and reporting on the project's performance with respect to the relevant outcomes that are expected to be achieved through the use of the innovation in the project.
