Illinois Route 134 (IL 134) is a 5.62-longNaN-long east - west state route in northeastern Illinois. It runs from U.S. Route 12 (US 12) and IL 59 in Fox Lake to IL 120 (Belvidere Road) in Hainesville.
Illinois 134 is called Big Hollow Road in Fox Lake. In Round Lake, it is called Round Lake Road west of downtown, and Main Street east of downtown.
