Zumbro River Constructors was a consortium of Fluor, Ames Construction, Inc., and Edward Kremer & Sons, Inc. responsible for the TH 212 road, interchanges, bridges, cross-streets, and signals and lighting, etc.
The construction schedule accommodated constraints posed by limited road closure time frames, issues associated with placing noise berms atop the 48-inch sewer, and sequencing of bridge activities to accommodate settlement periods of 3 to 9 months and to assure traffic access. In addition, to counteract the peaty, organic deposits, Zumbro used a lightweight fill of shredded tires and / or geofoam blocks to decrease the weight of the load, thereby reducing the potential for compression.
As part of the joint venture, Fluor designed, restored, or purchased 156 acres of wetland credits and protected the "Big Woods" ecosystem by conscientious design and construction.
Roads and Bridges magazine recognized the project was as the "Number 1 Roadway Project for 2007".
The project also received the Federal Highway Administration 2007 award for "Excellence in Utilities Project Management."
Additionally, it was the first highway construction site to receive Minnesota Safety and Health Achievement Recognition Program (the Minnesota's OSHA Voluntary Protection Program) recognition.
The project also achieved 1 million hours of safe work without an accident.
