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. In 1972, as traffic patterns shifted, these alternates to US highways became unnecessary and fell out of favor. U.S. Route 330 U.S. Route 330 (US 330) was a U.S. Highway that traveled from Galt to Lynwood, and was in service 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. US 330 branched off at Geneva, where US 30 ran along present Illinois Route 38 and Illinois Route 31, and ran east to Chicago. After several extensions on the west end, it became part of U.S. Route 30 Alternate from 1942 to 1971 and then Illinois 38 west of Mannheim Road since 1971.
