US 61, Dubuque-Dickeyville Eagle Point Overpass

With the help of IIW’s Construction Services team, the Wisconsin Department of Transportation made significant traffic control improvements to a highly trafficked U.S. Highway 61 and the connecting interchanges.

Throughout the project that spanned almost 2 years, IIW provided the materials testing, erosion control inspections, traffic control inspections and construction administration with the use of DOT Field Manager software.

IIW helped the DOT complete the project over several phases to reduce the impact that the construction would have on the regular flow of traffic.

This project also included rehabilitation of a bridge, reconstruction of approach pavement, temporary traffic crossovers and construction of a new pre-stressed concrete girder bridge on USH 61 and State Trunk Highway 151.

It included significant traffic control and staging requirements to improve the USH 61/STH 35 interchange, including a temporary traffic signal installation on STH 35. This allowed the structure rehabilitation and construction to occur while maintaining traffic through the project area at all times.

To accommodate structure construction at US 61’s four-lane divided highway, crossovers were constructed and the southbound traffic was shifted to the northbound inside lane to allow closure of the southbound lanes and construction of the new 175’ pre-stressed three-span concrete girder bridge on the northbound lane. Once the finishing touches were complete, crews removed the crossovers to provide an efficient traffic pattern.
