JANESVILLE—The state Department of Transportation is hosting a pair of meetings in Janesville on Tuesday to give the public updates on expansion work set to roll out this fall on Interstate 90/39.

The DOT plans construction to expand I-90/39 northbound lanes starting in Janesville after Labor Day, and the DOT in the months to come tentatively plans similar work on an eight-mile stretch from Janesville's south end to Hart Road near Beloit.

The DOT is hosting two informational meetings: one for the general public and another earlier in the afternoon for members of the area business community. The sessions are set up so the DOT can update the timelines for both expansion projects.

The project is part of the DOT's 45-mile expansion project to widen the Interstate from four lanes to six between Beloit and Madison and to beef up the Interstate to eight lanes through Janesville.

Under DOT plans announced earlier this year, crews will spend most of September readying a traffic crossover just north of Racine Street on Janesville's south end.

By October, the crossover will shift northbound traffic to two narrow diversion lanes on the southbound side of the Interstate between Racine Street and the Highway 14 interchange on the city's north end.

That four-mile swath of highway and reconstruction and expansion on the Interstate's northbound lanes mark the start of the DOT's expansion of the road from four lanes to eight through Janesville.

An eight-mile section of the Interstate from Janesville south to Beloit will undergo the same process in the northbound lanes, with work starting in spring 2018, the DOT said earlier.

After that, the DOT would expand the Interstate's southbound lanes, according to earlier timelines.

All told, the expansion through Janesville won't be completed until midway through 2020, and interchanges on the city's north side won't be fully tied into the new lane configuration until 2022 at the latest, according to DOT earlier timelines.
