› Rusty Patched Bumble Bee
The 9.8-mile Elgin-O’Hare Expressway stretched from Lake St., Rte. 20 in Hanover Park, east to Thorndale Ave, reaching neither Elgin nor O’Hare.
In 2013, Illinois Tollway took ownership of the corridor and the Elgin O’Hare Western Access Project (EOWA) was announced to extend the Elgin-O’Hare Expressway (IL-390) east to a new tollway, I-490 on the western edge of O’Hare Airport.
In 2018, planning was begun to improve the western terminus at Lake Street.
