I-94 Mitchell Interchange Reline – 2013 Rehabilitation Project of the Year

By: Contech Engineered Solutions

Only a year after installing a triple, 60-inch-diameter reinforced concrete equalizer pipe under 30 feet of cover at Mitchell Interchange on I-94 in Milwaukee, WI, the pipe needed to be relined due to structural cracks.

A 54″ corrugated steel pipe from Contech Engineered Solutions was chosen as a more economical and long-lasting solution than the other two alternatives considered.

Benefits of CSP include a proven service life that can exceed 100 years with proper specification, sustainability from recycled material, strength, flexibility, versatility, and lightweight material.

By using homogenous material, CSP eliminates failures caused by stress cracks, shrinkage cracks, and air voids.
