The Mitchell Interchange was reconstructed to have all traffic entering and exiting from the right. This design has eliminated confusion and improved safety. One of the more significant changes is the rerouting of maneuvers to and from 27th Street and I-94 South. Traffic on 27th Street will utilize the I-94 EAST (SB) entrance ramp from Layton Avenue to access I-94. Three tunnels were included in the design (one tunnel from I-94 WEST (NB) to I-43/894 west and two tunnels from I-43/894 east to I-43/94 north). The Mitchell Interchange was completed in Fall 2012.

The College Avenue Interchange was reconstructed to a tight diamond interchange. The ramp connections were brought in closer to I-94 which allows more space for the adjacent cross streets and improved traffic operations. The park and ride lots in the NE and SW quadrants were also reconstructed. The interchange was completed in 2009.

The Rawson Avenue interchange will be reconstructed to a tight diamond interchange. This means that ramp connections with the cross street will be brought closer to I-94. Doing this allows more space between the ramp and the adjacent cross streets – 13th Street and 20th Street, for better traffic operations.
The interchange construction is scheduled to be completed in Fall 2013.

The Ryan Road interchange will be reconstructed to a tight diamond interchange. This means that ramp connections with the cross street will be brought closer to I-94. Doing this allows more space between the ramp and the adjacent cross streets – 13th Street and 20th Street, for better traffic operations.
The Ryan Road Interchange will begin in Spring 2014 and is scheduled to be completed in Fall 2014.

The existing interchange at 27th Street and I-94 will be reconstructed from a half diamond interchange to a full diamond interchange. This interchange will be moved approximately a half mile further north to avoid impacts to the Root River environmental corridor and will improve spacing with the Seven Mile Road interchange. It will be built with a connection to 27th Street.
The Elm Road Interchange and mainline are tentatively scheduled to be constructed in 2017.

The existing crisscrossing ramp/frontage road configuration at 7 Mile Road will be reconstructed to eliminate the unsafe movements. The entrance/exit ramps will be configured as a diamond interchange. The east frontage road will be routed around current businesses and residences that are adjacent to the existing frontage road. The west frontage road will be routed west of 7 Mile Fair. Storm water detention ponds are planned for the NE and SE quadrants of the interchange.
The 7 Mile Road Interchange and mainline are tentatively scheduled to be reconstructed in 2019.

The entrance/exit ramps will be constructed with a partial cloverleaf configuration, similar to the existing configuration. The east frontage road will be realigned east of its current configuration north of Old Hwy 11 and the west frontage road will be realigned west of its current configuration north of 58th Road. 58th Road between the frontage roads will also be improved as part of this project.
The WIS 11 Interchange and mainline are tentatively scheduled to be reconstructed in 2020.

The existing crisscrossing ramp/frontage road configuration at County KR will be reconstructed to eliminate those unsafe movements. The entrance/exit ramps will be configured as a diamond interchange. The east and west frontage roads will be routed around current business and residences adjacent to the existing frontage road. The stream along County KR, east of I-94, will be realigned. A storm water detention pond is planned for the SE quadrant of the interchange.
The County KR Interchange and mainline are tentatively scheduled to be reconstructed in 2018.
