Local Option Sales Tax

Since 2010, the Linn County Secondary Road Department has received more than $36 million in local option sales tax revenue. These funds have accelerated Linn County’s 5-year construction program by paving 106 miles of roads (30 percent of the paved system), three bridge projects, and three culvert replacement projects. The majority (94 miles) of the paving projects were concrete overlays.
