State Trunk Highway 55/62 Interchange, Geosynthetic Liner System and Performance Monitoring
Brian Albrecht, P.E. – Short Elliott Hendrickson

Reconstruction of the State Trunk Highway 55/62 interchange adjacent to the Minneapolis St. Paul International Airport required lowering the surface of TH 62 below the existing groundwater table to provide adequate vertical clearance under the proposed TH 55 overpass. A change in state law, that occurred after construction had already commenced, resulted in a need to redesign the interchange so TH 62 could be constructed without permanent dewatering to maintain the water table below the surface of the road. The redesign utilized a geomembrane/geosynthetic clay liner system to create a water resistant barrier under the roadway. Uplift protection for the road and liner was provided by the weight of the road and a two stage pressure relief system. The presentation will cover the design and construction of the liner system, and the results of 30 months of post construction performance monitoring.
