- ROADWAYS:
- Reconstruction activities will include bridge demolitions which will require closure of roadways under the Interstate, including US 14, WIS 26 and Kennedy Road.
- Advanced notice of the roadway closures will be announced to area media, as well as posted on the I-39/90 project website and project Facebook page.
- Advanced notice of the roadway closures will be announced to area media, as well as posted on the I-39/90 project website and project Facebook page.

- Reconstruction activities will include bridge demolitions which will require closure of roadways under the Interstate, including US 14, WIS 26 and Kennedy Road.
- INTERCHANGES:
- The I-39/90 and WIS 26/Milton Avenue interchange will be reconstructed into a Diverging Diamond Interchange (DDI).
- Wisconsin’s first DDI opened in fall 2016 at the I-39/90 and WIS 11/Avalon Road, south of Janesville.
- Watch the narrated animation video and other information on the WIS 26 DDI.
- The I-39/90 and US 14/Humes Road interchange will be reconfigured to a diamond interchange with traffic signals.
- A Collector/Distributor (C/D) lane system will be constructed on I-39/90 at the WIS 26 and US 14 interchanges to separate high-speed Interstate through traffic from interchange traffic merging on and off I-39/90.
- The C/D lanes are dedicated lanes parallel to I-39/90 and separated from the Interstate by a concrete barrier. View the C/D navigation map.
- Traffic exiting at WIS 26 or US 14 will need to merge off at one location and choose the appropriate ramp lane to their destination.
- The lane system, which improves traffic flow and safety, is in effect in locations throughout the state with the closest at I-39/90/94 and US 151 on Madison’s east side.
- The northbound C/D lanes will open in fall 2020, and the southbound C/D lanes will open in fall 2021.
- The C/D lanes are dedicated lanes parallel to I-39/90 and separated from the Interstate by a concrete barrier. View the C/D navigation map.
- The I-39/90 and WIS 26/Milton Avenue interchange will be reconstructed into a Diverging Diamond Interchange (DDI).
- NOISE BARRIERS: View information on I-39/90 noise barriers.
- In 2021, noise barrier construction will be completed along I-39/90 southbound between the US 14 and Mount Zion Avenue.
- Also, noise barrier walls will be installed in 2021 on the southbound side of I-39/90 near Kennedy Road.
- All lane restrictions, ramp and road closures, and work operations are weather dependent and subject to change.
- Please continue to be alert, eliminate distractions when driving and don’t tailgate in work zones!
The I-39/90 construction work in Janesville is scheduled to be completed in fall 2021.
In 2022, US 14/Humes Road will be reconstructed to an urban roadway between Deerfield Drive and WIS 26/Milton Avenue (view the US 14 planned improvements ). A sidewalk/shared used path will be built on each side as part of the project. Lane and turn restrictions are anticipated during this six-month project, as well as full closure of US 14 from Pontiac Drive to Milton Avenue (view the construction staging ). Motorists will be required to use alternate routes.
