Schedule: August 2010 to November 2011
Location: 9th Avenue Interchange, US 41 Mainline from 1500 feet north of Witzel Avenue, to one mile south of the WIS 44 overpass.
Description: This project involves temporary widening of the southbound US 41 lanes during the fall of 2010 to provide a staged construction zone in which 3.2 miles of US 41 will be reconstructed. There will be an additional turn lane added on WIS 21. In 2011, the 9th Avenue bridge over US 41 will be demolished and rebuilt as a decorative bridge. Two retaining walls will be built in front of the abutments. The 9th Avenue interchange and the ramp terminal intersections will be reconstructed, and four roundabouts will be installed.
be built in front of the abutments. The 9th Avenue interchange and the ramp terminal intersections will be reconstructed, and four roundabouts will be installed.
November 28 to December 2: Most contract work will be complete. The traffic control contractor will continue to remove traffic control devices.
December 5 to December 9: The electrical contractor will be installing signal bases at both the northbound and the southbound US 41 on ramps at WIS 44 on Monday and Tuesday. There will be outside lane closures in both directions during the day. All other contract and punch list work will wrap up in the spring, prior to May 18, 2012.
Traffic impacts: The 9th Avenue Interchange is 100% open to traffic. US 41 between WIS 21 and WIS 26 is open to three lanes of traffic in each direction. There may be various daytime lane closures to perform punch list items of work; however, US 41 will still have two lanes open to traffic remaining during these closures.
