Project Overview
The proposed project consists of:
- Resurfacing 16.9 miles of I-39 by milling and overlaying I-39 and its shoulder pavements.

- Milling and overlaying the ramps, paved shoulders and crossovers at WIS 73 (Plainfield), County D and County W Interchanges.
- Restoring gravel shoulders.
- Replacing guardrail and culverts.
- Cleaning and opening underdrain pipes.
- Replacing missing delineators.
Traffic Impacts
I-39 will remain open to traffic, but construction will be completed using single-lane closures. Temporary closures might be necessary to improve the ramps at WIS 73, County D and County W.
