About this Project

The Wisconsin Department of Transportation hired Ayres Associates to provide construction observation on a first-of-its-kind project in 2013 to repair approximately 500 concrete joints along Interstate 94 near Hudson, Wisconsin. The result is longer-lasting repairs that allow traffic back onto the lanes more quickly.

Roughly 210 precast panels were used during overnight repairs, and 300 joints were repaired using cast-in-place panels. The quick precast panel process was used primarily on the center lanes of the interstate, on which two lanes of traffic closure is necessary for repairs. The Fort Miller Co. and Wieser Concrete supplied materials for the project, and Cornerstone USA LLC was the prime contractor. Fort Miller provides engineering, specialized forming, and grading equipment and on-site installation training required.
