Drivers should expect nighttime lane closures on the northbound and southbound Interstate 39/90 at Siggelkow Road as crews start work on the bridge Wednesday.
Crews will start construction on the southbound bridge just south of the Beltline interchange near Madison Wednesday, according to a Wisconsin Department of Transportation release.
Two lanes will be kept open to traffic in each direction during the day, officials said. Starting in late May, traffic on the southbound interstate will be shifted to the northbound side during the southbound bridge reconstruction.
Siggelkow Road will stay open to traffic in both directions until mid-May, according to the release. Starting May 16, Siggelkow Road will be closed at the interstate until November. During the closure, traffic on Siggelkow Road will not be able to go under the interstate.
The $5.7 million project is expected to be completed in November.
