The Lincoln Highway’s original route through Marshall County went right through Marshalltown. It wasn’t relocated onto a straightaway until the end of 1947. The route through the city passed the Marshall County Courthouse on the north side. The courthouse, built with local limestone, was dedicated Nov. 18, 1886, and then extensively restored 90 years later.

When the cutoff opened, travelers on new 30 accidentally bypassed the city altogether, according to articles from the Times-Republican. The state responded by retaining most of the western portion of the bypassed route and, to show it was related to 30, designated it IA 330. It stayed in the state system until the day after Christmas 1989, when 330 was rerouted north from the intersection above to Albion, leaving only a fraction of a mile running west from the intersection to E41.
