The majority of the bridges in the country are the small, single-span bridges that are commonly found on rural and local roads. As the infrastructure ages, weight restrictions or bridge closures are becoming more frequent. With limited resources available, transportation agencies must find innovative, cost-effective solutions to meet these demands. Prior to the Every Day Counts (EDC) initiative implementation of the GRS IBS was localized primarily in two counties within Ohio and New York; however, the benefits realized on those projects garnered national attention. As a result, the FHWA selected the GRS IBS technology in October 2009 as one of the EDC initiatives to actively promote throughout state and local transportation agencies. Implementation efforts have included the development of training materials and opportunities, such as design and construction guidance, web based presentations, workshops, peer exchanges, and showcases. As a result of these efforts, there are currently over 200 GRS IBS structures across the country in 44 states and territories, and the number is growing. This webinar provides participants with a background of the GRS IBS technology, a national perspective of the status of the implementation efforts, and the upcoming FHWA’s efforts for continued deployment of the technology. This webinar will also present several selected case histories to help illustrate the range of diverse projects that have incorporated the technology.
