Minnesota State Highway 10 – 2013 DOT Project of the Year

By: TrueNorth Steel


In June 2012, Duluth, MN, had a record 7 inches of rain in a two-day period that washed out a drainage structure on Minnesota State Highway 210.

The Minnesota Department of Transportation (MnDOT) designed a 144-inch by 180 feet of 10 gauge,  Aluminized Type 2, CSP as the replacement.

MnDOT placed an order with TrueNorth Steel on July 11, 2012, and the initial load for this order was ready for delivery July 16. All construction was completed for the drainage structure and backfilling of the pipe on Aug. 6, 2012.

The roadway was paved and opened for traffic on Aug 16. The relatively light weight of CSP pipe as compared to concrete eliminated the need to bring in a large crane to set the pipe, saving MnDOT a considerable amount of time and money.
