Interstate traffic to use signed detour route: US 14 and US 51
On Monday night (May 15), crews will finish removing the Manogue Road bridge over Interstate 39/90 north of Janesville. For the safety of the traveling public and construction crews, I-39/90 northbound will be completely closed to all traffic, between Janesville and Edgerton.
- 10 p.m. Monday (May 15) to 5 a.m. Tuesday (May 16) – I-39/90 northbound (westbound) is closed to all traffic between US 14 in Janesville and US 51 near Edgerton. Northbound Interstate traffic will be diverted off I-39/90 at Janesville Exit 171B and redirected to the signed detour route of US 14 in Janesville and US 51 through Edgerton.
o The northbound on ramps will also be closed from US 14 (Humes Road) and WIS 26 (Milton Avenue) in Janesville. Alternate routes are required.
o One lane will remain open on I-39/90 southbound.
Motorists may encounter backups and delays on the detour route depending on traffic volumes. Motorists who typically use I-39/90 during the overnight hours should plan ahead and allow for extra time to reach their destination.
In conjunction with this overnight demolition, crews will pour concrete for the I-39/90 northbound bridge over the Rock River, near Edgerton and Newville. One lane will be closed on I-39/90 northbound in this area starting at 8 p.m. Monday (May 15) until the northbound Interstate closure at 10 p.m. Monday (May 15).
All closures, lane restrictions and work operations are weather dependent and subject to change.
Construction-related noise is expected during these nighttime operations as crews jack-hammer and remove the bridge deck. Once the existing structure is removed, crews will begin to construct the new bridge which will improve safety, meet current design standards and lengthen the bridge over I-39/90 to accommodate the Interstate expansion between Beloit and Madison.
The $2.2 million Manogue Road bridge project is expected to be completed in late August 2017.
