From Infogalactic: the planetary knowledge core
The DuPage County Highway System is a county-maintained system of arterial highways in DuPage County, Illinois, U.S.. County highways in DuPage County are marked with the standard M1-6[1] pentagon-shaped shield on the base of traffic signals at intersections with other county highways. They are not marked on any freeway or tollway exits, or signed with separate reassurance shields. In addition, although concurrencies of county highways exist in the county, they too are not explicitly signed as such.
County Highways 47, 48, 49, 55 and 57 all refer to segments of the Illinois Prairie Path and the Great Western Trail, major bike trails through DuPage County. No motorized traffic is allowed on these trails/highways.[2]
