If you exit I-90 at Arlington Heights Rd. on a Saturday night and see a ‘light up’ construction arrow on the North side of I-90, it’s road block. You can avoid it by heading South, but it will take you about 15 minutes to complete this detour. Turn left at Oakton, left at Busse and left at Algonquin. When that’s over with you’ll be 1 block North of where you started. If your driving North on Arlington Heights Rd. you can turn around in a tiny 20 tombstone graveyard just South of I-90 on the West side of the street.
