IL 31 is called Richmond Road north of IL 120 and Front Street south of IL 120 in McHenry, Main Street in Algonquin, Western Avenue in Carpentersville, Eighth Street in West Dundee, State Street in Elgin, La Fox Street in South Elgin, Second Street in St. Charles, First Street in Geneva, Batavia Avenue in Batavia, Lincolnway Street in North Aurora, Lake Street (Southbound) and River Street (Northbound) in Aurora, and Lake Street in Montgomery. It is also, along with IL 25, signed as part of the Fox River Valley area. IL 31 between Aurora and Geneva was considered part of the Lincoln Highway transcontinental route.
SBI Route 31 traveled from Quincy to Canton along various routes. This was dropped in 1935. In 1937, it was reapplied along other routes on its modern routing. There have been no changes to the routing since.
U.S. Route 430Edit
U.S. Route 430 (US 430) was commissioned from 1926 to 1934 in the U.S. state of Illinois, and traveled from Aurora to Crystal Lake. It traveled concurrent with US 30 from Aurora to Geneva at present-day IL 38. US 430 was dropped in 1934 and replaced in its entirety with IL 31.
The intersection of IL 31 and IL 120 is now the most congested intersection in McHenry County.
A bypass of McHenry continues to appear in documents planning for a Metra station at Prairie Grove, that include an interchange with the existing IL 31 alignment and the proposed west McHenry bypass alignment to the north of Gracy Road.
The west McHenry bypass was originally planned to travel over undeveloped farm lands from north of IL 31 and Gracy Road to IL 120 and Ringwood Road. The corridor was planned to be protected from development in the mid-1990s, but because of a lack of funding, the corridor was never protected from development and has since been developed.
The Western Algonquin Bypass is not the only limited-access bypass on the table as of 2015. A southern Algonquin bypass is being constructed as the Longmeadow Parkway, that will have a grade separation with Route 31.
