Racine St. Interchange (IH-39-STH 11)
Project Description: This complex interchange reconstruction project was completed with an extremely tight schedule under staged construction. The project included the conversion of the existing cloverleaf interchange to a diamond configuration to improve safety and included complex multi-lane roundabout ramp terminals which were constructed in four stages. The interchange remained open to traffic during construction to allow minimal disruption to the 13,000 vehicles per day using the interchange. Structure construction over IH-39 required careful coordination with project stakeholders. Extensive public interaction was required throughout the project to accommodate many local businesses including heavy traffic generators such as St. Mary’s Hospital/Dean Clinic and a local hotel. Batterman Staff worked closely with the Corridor Management Team and the WisDOT Communication Specialist to ensure the public was clearly informed and always aware of upcoming changes to traffic patterns. Project highlights included temporary traffic signals at multiple intersections, new signals and street lighting, colored concrete, five infiltration basins, and extensive landscaping.

Biggest Challenge and How it was Solved: This was one of the first Mega Projects on the IH-39 corridor with an aggressive schedule (June to November). It was a staged interchange with all traffic movements remaining in operation during construction. Crews worked day and night to complete stages on time and looked for efficiencies in each staged section.
