US 41/WIS 441 Corridor Operational Analysis Northeast Region, WI
The Wisconsin Department of Transportation (WisDOT), Northeast Region, worked with raSmith to identify existing and future safety and operational issues and develop conceptual geometric and operational improvements on US 41/WIS 441. WisDOT was also preparing for the conversion of this segment of US 41 to an interstate highway.
raSmith’s traffic engineers used their extensive roundabout and interchange analysis expertise to develop cost-effective and feasible design solutions for 52 intersections at 18 interchanges along the corridor.
WisDOT requested that our traffic engineers identify short- and long-term interchange improvements. Short-term solutions included lane additions, signal timing changes, pavement markings and minor geometric improvements. The long-term solution of a full interchange reconstruction required the analysis of traditional and unconventional options, including similar configuration, roundabouts, diverging diamond or a single point urban interchange (SPUI).
The completed study offered a road map for WisDOT to prioritize which segments should be considered for future construction and how projects could be grouped in the future.
