A Case Study: Geosynthetic Reinforced Soil–Integrated Bridge Structure (GRS-IBS)

Since 2009 the St. Lawrence County Highway Department in New York State has constructed seventeen geosynthetic-reinforced soil-integrated bridge structure (GRS-IBS) bridges. This is as a result of a bridge inventory which showed that there were 81 county-owned bridges that were labeled as deficient. Twenty-seven of the 81 were placed on a 2014 priority replacement list due to a condition rating of ≤ 4.5 out of 7. There was a need to find a faster, more economical and better method for the replacement of these bridges. Thus the decision was made to use the GRS-IBS approach. This paper will present a case study of one such structure constructed by the St. Lawrence County Highway Department.
