Geosynthetics allow widening of road adjacent to an urban lake

This article reports on the reconstruction of Hennepin County State Aid Highway 112, the first phase of which was completed in Fall 2018. The five-month project involved a widening of the existing highway and the addition of a bike trail between Minnesota's Long Lake and the road. A 1,400-foot geogrid-reinforced steep (1H:1V) slope (RSS) was constructed with high-strength geotextile along the embankment base in order to facilitate road embankment widening without encroaching into the lake. The article describes the RSS construction staging, sheeting installation and dewatering processes, the RSS fill material and geogrid reinforcement, and the RSS facing.
