U.S. Route 12(US 12) in the U.S. state ofIllinoisis an arterial highway that runs northwest to southeast through theChicago metropolitan area.It enters Illinois at theWisconsinborder north ofRichmond,and exits intoHammond, Indiana,fromChicagonear the foot of the onramp to theIndiana Toll Road(Interstate 90,or I-90); as it exits Illinois, the route is also concurrent withUS 20andUS 41.Within Illinois, US 12 runs for a distance of 85.14 miles (137.02 km).[1]
Route description
[edit]Richmond to Des Plaines
[edit]The westernmost portion of US 12 in Illinois runs south from the Wisconsin border, betweenGenoa City, Wisconsin,andRichmond.North of Genoa City, US 12 is a four-lane limited-accessfreeway.In Illinois, it reverts to a two-lane, undivided surface road prior to a traffic light withIllinois Route 173(IL 173) north of Richmond. South of Richmond, through traffic on US 12 must turn left atIL 31to continue. It continues to theFox Lakearea, at which point it becomes a four-lane divided highway, with occasional interchanges.
US 12runs concurrentlywithIL 59south of Fox Lake at an access-controlled interchange, and then intersects withIL 134at a traffic light. InVolo,there is a traffic light withIL 120,but then reverts to an expressway, with interchanges forIL 176(Liberty Street) andIL 59.From the state line to this point, US 12 is also marked as the main route for the Fox River Valley, which continues south on IL 59.
InLake Zurich,US 12 picks up the name Rand Road, named so for a former name of the city ofDes Plaines.[3]There is also an intersection withIL 22(Main Street). US 12 proceeds towardDeer ParkandKildeerbefore enteringCook CountyinPalatine.US 12 then briefly overlapsIL 53between Hicks Road andIL 68(Dundee Road) in northeast Palatine. At the expressway portion of IL 53, US 12 traffic can only access southbound IL 53.
From IL 53, US 12 travels through the heavily populated areas ofArlington HeightsandMount Prospect,intersecting withIL 83(Elmhurst Road) in Mount Prospect. US 12 enters the Des Plaines area atIL 58(Golf Road) and joins withUS 45(Des Plaines River Road) north of downtown.
In Des Plaines, US 12/US 45 separates, as southbound traffic travels on Graceland Avenue, while northbound traffic runs one block east. In downtown Des Plaines, US 12/45 has a major intersection withUS 14(Miner Street) at a busy at-grade crossing with theHarvard Subdivisionof theUnion Pacific Railroad.
Des Plaines to Hickory Hills
[edit]After turning south from Des Plaines, US 12/US 45 forms a major north–south artery through the western suburbs. North ofCermak Road,the route is known as Mannheim Road, while, south of Cermak Road, it is known as La Grange Road. The distance from the intersection of US 12/US 45 and US 14 in Des Plaines to the US 12/US 20/US 45 split in Hickory Hills is 9.97 miles (16.05 km).
US 12/US 45 runs through various streets in Des Plaines before following Mannheim Road north ofO'Hare International Airport.This routing also closely parallels the north–south orientation of theCanadian National Railwayrail line. US 12/US 45 intersectsIL 72(Higgins Road) at the northeast corner of the airport and then travels south along the eastern border of the airport. There is a full interchange withI-190for passenger airport traffic. At the southeast corner of the airport, a signalized intersection terminates a brief expressway portion ofIL 19(Irving Park Road).
South of Irving Park Road, US 12/US 45 travels beneath the Bensenville Bridge onI-294(Tri-State Tollway) while also crossing over theCanadian Pacific Kansas Cityrailyard inFranklin Park;however, there is no interchange with I-294 at this point. This rail line also carries theMetra'sMilwaukee District West Linetrains. InMelrose Park,US 12/US 45 has a grade-separated intersection withIL 64(North Avenue), a major east–west artery west of Chicago. About a mile (1.6 km) south, US 20 joins with US 12/US 45 to form a triple concurrency over theUnion Pacific Railroad's Proviso Yard as well as the mainline tracks of the Geneva Subdivision (Union Pacific/West Line).
US 12/US 20/US 45 continues south and becomes the eastern endpoints of two state routes:IL 56inBellwoodandIL 38inWestchester.In between lies a full intersection withI-290(Eisenhower Expressway). In downtownLa Grange,US 12/US 20/US 45 intersects withUS 34(Ogden Avenue), making it the only location in the Chicago area (and possibly the state of Illinois) where four U.S. Highways intersect.[citation needed]In addition, there is a level-grade crossing withBNSF Railwaytracks very near the intersection, which leads to frequent traffic backups and delays.[4]
South of La Grange, US 12/US 20/US 45 has a full interchange withI-55(Stevenson Expressway). It then crosses theDes Plaines RiverandChicago Sanitary and Ship Canalbefore a complex interchange withIL 171(Archer Avenue). A ramp from I-294 to US 12/US 20/US 45 formerly existed but was removed in the late 1990s due to safety concerns. Just south of the Tri-State Tollway, US 12/US 20/US 45 becomes southbound 96th Avenue, passing through theForest Preserve District of Cook Countyfor nearly two miles (3.2 km) before US 12/US 20 split from US 45 onto eastbound95th Street.
Hickory Hills to Chicago
[edit]After turning off the US 45 routing in Hickory Hills, US 12/US 20 runs east on95th Streetfor 16.31 miles (26.25 km)—combined with a concurrency withUS 41,this segment runs for an additional 18.02 miles (29.00 km) into the state ofIndiana.
The 95th Street portion of US 12/US 20 is a four-lane undivided arterial surface street through the southern suburbs ofPalos Hills,Bridgeview,Oak Lawn,andEvergreen Park.It serves the main commercial areas of these communities and the Chicago south side neighborhoods ofBeverly,Washington Heights,Roseland,Burnside,Pullman,Calumet Heights,South Deering,andEast Side.
In Bridgeview, US 12/US 20 has interchanges with I-294 andIL 43(Harlem Avenue). In Oak Lawn, it intersectsIL 50(Cicero Avenue). Further east, in Chicago, US 12/US 20 nearly intersectsIL 1(Halsted Street); IL 1 technically terminates atI-57a half mile (0.80 km) south. US 12/US 20 then has an interchange withI-94(Dan Ryan Expressway) just north of the I-57/I-94 split. Shortly after bridging theCalumet River,US 12/US 20 joins with US 41.
The concurrent US 12/US 20/US 41 combination runs south on Ewing Avenue beneath theChicago Skyway,narrowing from two northbound and southbound lanes to one northbound and one southbound lane before turning onto Indianapolis Boulevard, a six-lane divided highway. At 104th Street, there is a traffic light for a relocated offramp (from 106th Street) from the Chicago Skyway to Indianapolis Boulevard. The southbound onramp to theIndiana Toll Roadis still located at 106th Street.
The Illinois portion of US 12/US 20/US 41 terminates beneath the I-90 bridge over Indianapolis Boulevard; this is also where the Chicago Skyway becomes the Indiana Toll Road.
History
[edit]In 1928, US 12 followed its current route south from Wisconsin into Richmond. It then continued straight on what is nowIL 31toCrystal Lakeand then ran along what is now US 14 into Chicago. This route began to be depicted on Chicago maps in 1932 along the Northwest Highway,Foster Avenue,Lake Shore Drive,South Parkway (now most likely the 57th Street/Cornell Avenue combination),Stony Island Avenue,and 95th Street.
From 1928 to 1929, the section between the Wisconsin state line to Crystal Lake was being constructed; this segment was designatedTemporary U.S. Route 12(Temp. US 12) at the time.
In 1938, US 12 was moved north off the US 14 routing to the current routing toDes Plaines.In addition, US 12 was moved to what is nowMannheim Road,La Grange Road,and 95th Street. The former US 12 becameU.S. Route 12 City(US 12 City).[5][6]
In 1939, US 12 was moved to a bypass aroundLake Zurichand widened to four lanes. Old Rand Road was the name given to the former US 12 alignment.[6]The original 1939Elgin, Joliet and Eastern RailwayRailroad 4 span concrete bridge over the US 12 bypass remains in Lake Zurich with telegraph poles visible on the bridge. The original pot hole full 1939 asphalt pavement has since been resurfaced including replacing with concrete lanes and widening from through lanes to six through lanes between IL 22 and Ela Road in a project in 2007.
In the early 1950s, US 12 was moved to a bypass aroundWaucondaand widened to four lanes extending to IL 120 in Volo. Old Rand Road was the name given to the former US 12 alignment.[7][8]The original pothole-full 1950s asphalt pavement with double yellow lines visible in the west bound lanes between Old McHenry and Old Rand roads has since been resurfaced in 2013. Mature trees in the interchange grassy areas and 1950s style motels remain in Wauconda.
In the late 1950s, US 12 was widened to four lanes extending to Fox Lake.[9][10]Mature trees lining the frontage roads and 1950s-style motels and diners remain in Fox Lake. US 12 in Illinois has not been widened further northwest since then.
There were no further changes to the US 12 routing until 1960, when US 12 City becameU.S. Route 12 Business(US 12 Bus.).[10]In 1963, US 12 was moved onto the Chicago Skyway and becameU.S. Route 12 Toll Business(US 12 Toll Bus.) until 1968, when all US 12 Bus. designations were dropped.[2][11]
In Illinois, the highway has been designated as the Iron Brigade Memorial Highway to honor the Civil War Union Army unit,[12]a designation it also has in Michigan,[13]Indiana,[14]and Wisconsin.[15]
