Maine Bridge Uses First GRS Wall in a Marine Environment

This GRS-IBS solution is the first in a marine environment.The City of North Haven is located on an island off the coast of Maine. This town was faced with a unique challenge when a bridge needed replacing. Looking for an economical option, designers decided on a Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS). This solution allowed the town and DOT to re-use an existing bridge pier, beat the construction deadlines, and provide a modern bridge solution for this small town.
