[edit] Route description

Illinois Route 38 in eastern Glen Ellyn

Illinois 38 runs along the historical Lincoln Highway for much of its length, and parallels Interstate 88 as well. Illinois 38 serves numerous 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.

Through DeKalb, Route 38 continues to be known as the Lincoln Highway. From Kirk Road in Geneva to Hinsdale, Illinois 38 is called Roosevelt Road.

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 hour.

[edit] History

The Lincoln Highway was routed along modern-day Route 38 between Geneva and Dixon. When numbered US Highways began to replace named cross-country roads (like US 30 for the Lincoln Highway), this stretch of highway was signed as Alternate US 30. As traffic patterns shifted, these alternates to US highways became unnecessary and fell out of favor; in 1972 [1] Alt US 30 was re-signed as Illinois Route 38. The number 38 was chosen because of the similar pronunciation to "30-A".

[edit] U.S. Route 330

U.S. Highway 330 was a federal highway located in Illinois that ran from Galt to Lynwood, and was commissioned from 1926 to 1942. It has since been replaced in its entirety by Illinois Route 38 west of Bellwood, and by other local roads east of Bellwood to Lynwood.

U.S. Route 330 branched off at Geneva, Illinois, where US 30 ran along present Illinois 38 and Illinois 31, and ran east to Chicago. After several extensions on the west end, it became part of U.S. Route 30 Alternate ca. 1942 and Illinois 38 ca. 1971.
