WISCONSIN (CBS 58) -- As we head into road construction season, there is encouraging news about the freeway expansion along the I-94 corridor from southern Milwaukee County to Kenosha County. 

Crews have an aggressive schedule planned. The 13-mile stretch from Highway G south to Highway 142 should be expanded to four lanes in each direction by the end of the year. The good news is three lanes will remain open during the road work. 

"You'll be seeing a lot of dirt work and a lot of concrete going down. By the middle of this summer, we intend to have traffic switched to the new pavement, then we can build the northbound lanes," says Mike Burns, Project Manager for the Wisconsin Department of Transportation.

The northern part of the construction project, from Highway G up to College Avenue, will take a little longer but should be finished in 2020. 

The construction zone speed limit has been lowered to 60 miles per hour. Drivers are urged to be safe and avoid distractions.
