Project Description

The US 10/WIS 441 Tri-County Freeway is to be reconstructed and expanded. The project scope includes adding mainline capacity, constructing a new parallel bridge over Little Lake Butte des Morts (LLBDM), re-decking and widening the existing eastbound LLBDM bridge, reconstructing the system interchange between US 41 and US 10/WIS 441, reconstructing the interchanges at Racine Street (County P), Midway Road (County AP), Appleton Road (WIS 47), and Oneida Street (US 10), constructing multi-lane roundabouts at ramp terminals, and installing freeway lighting and ITS. The project goals include addressing existing safety concerns and meeting future traffic demands for this critical freeway system.

General Tasks

An analysis of six years of crash data (over 19,000 crashes) for both the freeway and 12 ramp terminal intersections. The analysis includes review of summarized crash data provided by WisDOT, calculation of the crash rates, detailed analysis of crash hot spots, and development of crash diagrams
