Illinois State Toll Highway Authority (abbreviated ISTHA, but commonly referred to as the "tollway authority"). I-355 runs from Interstate 80 in New Lenox north to Interstate 290 in Itasca, a distance of 32.5 miles (52.3 km). 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 (IL 53), a parallel two-lane state highway in central DuPage County. Initially, I-355 ran from Interstate 55 north to I-290. On November 11, 2007
, the tollway authority opened a southern extension of I-355 from I-55 to I-80, a distance of 12.5 miles (20.1 km); on its opening, the tollway authority changed the name of the tollway to "Veterans Memorial Tollway".
