Road construction season in the Southland this year will see the completion of one major project while another gets under way.

The widening of U.S. 30 along a nine-mile stretch from Harlem Avenue in Frankfort to Williams Street in New Lenox, which began more than two years ago, should wrap up this summer, perhaps even by the end of June.

But as that big project nears the finish line, another is just getting started.

This week, advance work began in preparation for the $90 million widening of LaGrange Road through Orland Park and Tinley Park.

Crews will work mostly at night to remove medians along LaGrange Road between 131st and 179th streets, and that will mean some lane reductions, although not during the height of the afternoon rush, according to the Illinois Department of Transportation.

Prep work for the ultimate widening of LaGrange Road to three lanes in each direction will also include the removal of trees along the street.

To start, crews will begin cutting out the median at 159th Street and work their way north, according to IDOT spokeswoman Jae Miller. Once the median is gone, asphalt will be put down so LaGrange Road continues to have two lanes northbound and southbound when the work to wide the road begins.

Although the widening work is supposed to start this year, Miller said when that will happen hasn’t yet been determined.

Removing the median and laying asphalt is scheduled to be completed by Aug. 1, Miller said. Daytime lane closures will occur between 6 a.m. and 2:30 p.m., and overnight closures won’t start until 7 p.m.

Closures are scheduled to take place Monday through Friday, and if the contractor needs to close lanes on weekends, IDOT has to approve them, Miller said.

Along U.S. 30, sound walls are going up east of Schoolhouse Road, and other finishing work includes curbs and gutters, recreational trails and removing temporary pavement that was installed during the construction.

In early June, after graduation ceremonies are held at Lincoln-Way Central, the intersection of U.S. 30 and Schoolhouse Road will be closed temporarily to northbound traffic, according to Will Nash, New Lenox village engineer.

Other road projects that will be continuing or will start soon include:

In Palos Heights, a project to resurface 76th Avenue between 127th and 131st streets is scheduled to begin this month and wrap up by the end of the year, according to IDOT.

Haven Avenue in Orland Hills is being resurfaced between 159th and 163rd streets. The work is scheduled to end next month.

In Homewood and Thornton, Ridge Road will be resurfaced from Halsted to Margaret streets, and Margaret will be resurfaced from Ridge Road to Schwab Street. That project is to begin this month and be completed by sometime in July.

In Lynwood and Sauk Village, Torrence Avenue will be resurfaced from Glenwood-Dyer to Steger roads, starting this month and finishing in July.

Along Interstate 57, from the Will County line to just south of 175th Street in Country Club Hills, crack sealing and pavement restriping is scheduled to begin in June and be over in August.

Work will continue on a $7.7 million project to widen 143rd Street to two lanes in each direction between Bell and Will-Cook roads. The project could be finished this year, Will County Highway Engineer Bruce Gould said.

While a start date hasn’t yet been set, a resurfacing of Laraway Road from Harlem Avenue in Frankfort to Illinois 52 in Joliet, a $2.2 million project, is also scheduled for this season.

In Green Garden Township, Manhattan-Monee Road is scheduled to be repaved from Center Street to Devonshire Lane.

In Lemont, reconstruction of the triangle of Derby Road, McCarthy Road and Archer Avenue is under way and will continue through October, according to village administrator Ben Wehmeier. Another Lemont intersection, McCarthy and Walker roads, will see improvements this year, including turn lanes, traffic signals and sidewalks, Wehmeier said.
