WIS 54 (Maple Drive to I-39)

design

The Wisconsin Department of Transportation (WisDOT) is in the process of developing plans for a pavement replacement project on WIS 54 between Maple Drive and I-39 in Portage County. This section of WIS 54 is approximately 1.5 miles in length. The existing pavement structure consists of asphalt overlaid with concrete. This atypical kind of overlay, concrete over asphalt, has resulted in an increased deterioration in the pavement, such as longitudinal and transverse cracking, spalling and shifting between slabs. The purpose of the project is to repair the deteriorating pavement. Proposed improvements include removing the concrete overlay on WIS 54, removing the asphalt underneath the concrete and adding 2 inches of base aggregate to the existing base layer. New asphalt will then be placed on top of the base layer. The roadway profile will be lowered by 2.75" through the pavement replacement. The project will also include replacement of select culverts, minor rehabilitation to a structure in the project limits, widening of the Hoover Avenue intersection, replacement of guardrail, pavement marking and centerline rumble strips.
