Illinois Route 38 is an west–east state highway that runs across northern Illinois. It runs from U.S. Route 52 (US 52) in downtown Dixon to US 12/US 20/US 45 (Mannheim Road) in Westchester. It runs concurrently with the Lincoln Highway between Dixon and the junction of Illinois Route 31 in Geneva where it transitions via State Street onto Roosevelt Road at the junction of Kirk Road and continues through the western suburbs to its terminus at the junction of Mannheim Road. Roosevelt Road continues on an additional 14 miles without a route designation until terminating at US 41 (Lake Shore Drive). Illinois Route 38 travels along the former route of US 330, that existed from 1926 to 1942. It spanned from Galt to Lynwood. Route description Illinois 38 runs along the historic Lincoln Highway for much of its length, and parallels Interstate 88 as well. Illinois 38 serves some cities that have no interchanges on Interstate 88. It enters the Chicago metropolitan area at Elburn, as this border is pushed west with the extension of the Metra rail system. Except in cities, Illinois 38 has two lanes west of Geneva. Illinois 38 generally has two lanes west of the Fox River, except in cities, and four lanes east of the river. From Villa Park to Interstate 294, Illinois 38 expands to six lanes and becomes a limited-access freeway with exits to Illinois Route 56, Illinois Route 83, Interstate 290 and Interstate 294. The ramp to Interstate 290 has an automated gate system that closes during high-volume periods, such as rush hours. History SBI Route 38 initially ran between Kampsville and Jerseyville. In 1937, IL 38's western terminus was truncated as IL 100 was extended south of Kampsville while its eastern terminus was extended to Mount Clare. By 1941, the original route of IL 38 was decommissioned and was replaced by IL 16, IL 112, and IL 138. It remained decommissioned until 1972 when Alt US 30 was partly replaced with Illinois Route 38 while the rest was removed. In 1914, one mile of a road near Malta, Illinois was paved with concrete. This was the first "Seedling Mile" of the concrete road on the Lincoln Highway. Seedling Miles were constructed on several portions of the Lincoln Highway to encourage the paving of the highway from coast to coast. The Lincoln Highway was routed along modern-day Route 38 between Geneva and
