Interstate 355
I-355 runs from I-80 in New Lenox north to I-290 in Itasca, a distance of 32. 5 miles. With the exception of a four-mile expansion in 2009, the highway is six lanes wide for its entire length. The tollway authority opened I-355 as the North–South Tollway in 1989 to ease congestion on Illinois Route 53 in central DuPage County.
