Sept 25 Aggregate Conference
Minnesota State Highway 23 faced the dilemma of too much traffic for a route that had existed since the 1920s. The 343-mile highway, is located about 80 miles northwest of Minneapolis.
To improve mobility and safety, the Minnesota Department of Transportation (MnDOT) decided to extend 7.7 miles of Highway 23. This concrete Paynesville Bypass project started in April 2010 and was completed in July 2012, a month ahead of schedule despite a one-month state government shutdown. Along with the construction of a four-lane divided bypass, the project included grading, construction of eight bridges, surfacing, and lighting.
Kraemer Trucking and Excavating, Inc., turned to ARM Member Coldspring because its nearby granite quarries had aggregate that could be used as a base for the highway project. Kraemer crushed 43,000 tons of granite aggregates from multiple Coldspring quarries to meet the project's specifications.
