This document discusses the first use of a geosynthetic reinforced soil integrated bridge system (GRS-IBS) in Illinois for the Great Western Trail project in Lombard. Key points: - GRS-IBS uses alternating layers of compacted soil and geosynthetic fabric for the walls and foundation of a bridge abutment, replacing traditional methods using piles and MSE walls. - For this project, large modular concrete blocks were used instead of cheaper CMU blocks, making construction more difficult and expensive than typical GRS-IBS projects. - Construction is underway and proceeding well. FHWA is monitoring the project to study wall movement over the next two years. - While more expensive
