DOT meeting focuses on alternate Interstate-90/39 route
EDGERTON—State transportation officials will be available Tuesday to discuss traffic improvements and an alternate route during reconstruction of Interstate 90/39 in the Janesville area.
Work is expected to begin in 2015 on the reconstruction and expansion of the Interstate between the state line and the Beltline in Madison. The project has been broken into three segments, although construction will occur on all three simultaneously.
Tuesday's public information session will focus on the central segment, which runs for 13 miles between County O south of Janesville and the Rock/Dane County line.
The Interstate will be rebuilt and expanded to eight lanes—four lanes in each direction—from County O to Highway 26. Six lanes will continue north.
Derek Potter, the Department of Transportation project manager for the central segment, said the primary alternate route involves highways 11, 14 and 51 on both sides of Janesville.
The route goes east on Highway 11 to Highway 14, then north and west to Highway 51 and then north back to the Interstate's interchange with 51 and Highway 73 north of Edgerton.
The state's plans on the alternate route include upgrading local road intersections for safety and better traffic flow, optimizing traffic signal operations and rehabilitating existing pavement. Most of the work on the alternate route will take place in 2015, Potter said.
The DOT last fall finished rebuilding the Racine Street interchange. This year, the state will repave the Interstate from Milwaukee Street in Janesville to just north of the Highway 51/73 interchange.
The majority of the I-90/39 expansion work starts in 2015 and should be finished in 2021.
