The majority of the bridges across the nation are small, single-span bridges commonly 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 for bridge construction. The Geosynthetic Reinforced Soil–Integrated Bridge System (GRS–IBS) may be an excellent alternative to help reduce bridge construction time and cost!
Prior to the EDC initiative, implementation of the GRS-IBS was limited to two counties within Ohio and New York. Now there are more than 200 GRS-IBS structures across the country in 44 states and territories, and the number is growing. This Every Day Counts (EDC) Exchange will present several case histories illustrating the range of diverse projects and design considerations to help others implement this type of construction. The webinar will also provide a brief overview of FHWA guidance on scour evaluation and countermeasure design as well as how scour can be successfully addressed when using GRS-IBS.
This EDC Exchange will be of interest to local, tribal and state transportation agencies that are looking for a cost effective solution to replace deficient bridges.
