Illinois Route 47 (IL 47) is a 169.76-mile-long (273.20 km) largely rural north–south state highway that runs from theWisconsin state border atHighway 120 nearHebron, toIL 10, just south ofInterstate 72 (I-72) nearSeymour.[1] IL 47 is in primarily rural areas but in several suburbs ofChicago, such asWoodstock andHuntley, traffic can be heavily congested.
IL 47 crosses most interstate highways in northern and central Illinois, but the largest towns that it serves areWoodstock (atUS 14),Huntley (atI-90),Lily Lake at (IL 64),Elburn (atIL 38),Sugar Grove (atUS 30),Yorkville (atUS 34),Morris (atI-80),Dwight (atI-55),Forrest (atUS 24),Gibson City (atIL 54), andMahomet (atI-74).

Illinois 47overlapsIllinois Route 72 andU.S. Route 20 atPingree Grove, a village approximately 60 miles (97 km) from Chicago; this concurrency is part of a so-calledwrong-way concurrency, where one can be driving both “south” on Illinois 72 and “north” on U.S. 20 at the same time. Route 47 also shares concurrencies withIllinois Route 9 and Illinois 54 in Gibson City,U.S. Route 30 inSugar Grove,U.S. Route 6 in Morris,Historic U.S. Route 66 in Dwight, andU.S. Route 150 in Mahomet.
The original route ended near where it ends today, however, in 1937, it was extended toDecatur via portions of modern dayIL 10 andIL 105. Only eight years later (in 1945) was it shortened back toMonticello (the old route became IL 105). One final change came in 1980 when IL 47 was moved back to its current southern terminus at IL 10 afterI-72 was built in the area.[2]
Widenings started occurring further north as early as 2009. A project to reconstruct the road to 4 lanes from Kreutzer Road to Reed Road throughHuntley was completed in October 2011, including completing all ramps at theI-90 interchange.[3] IL 47 was widened fromI-80 inMorris to Caton Farm Road south ofYorkville as part of thePrairie Parkway study–work was completed in 2015.[4] In 2015, the project to expand the section betweenIL 71 and Kennedy Road in Yorkville to 4-lanes was completed.[5] The partial interchange withI-88 betweenSugar Grove andElburn was made full with the completion of the missing ramps (usingelectronic toll collection) in 2019.[6]

TheIllinois Department of Transportation is proposing to add lanes to several portions of Illinois Route 47, which eventually would make it a 4-lane road from I-80 in Morris to I-88 in Sugar Grove, and from I-90 in Huntley to north of Woodstock.
