State Road 427 (SR 427) is a roughly northeast-southwest two-lane surface road between U.S. Route 6 (US 6) at Waterloo and the Ohio state line east of Hamilton. Fifteen miles in length, it is a child of U.S. Route 27 (US 27), which is now decommissioned north of Fort Wayne.

Route description

SR 427 begins in downtown Waterloo, in DeKalb County, where US 6 passes through town. It runs northeast to Hamilton, where it crosses into Steuben County. In Hamilton, it is concurrent with State Road 1 (SR 1) for less than a mile and passes to the southeast of Hamilton Lake. Leaving Hamilton, it heads east to the Ohio state line, where it meets Ohio State Route 34 into Edon, Ohio.

History

Before Interstate 69 (I-69) was completed between Fort Wayne and Auburn during the 1960s, SR 427 extended almost due south along what is now a north–south county road now identified as "Tonkel Road" in Allen county and "CR 427" between the Allen-DeKalb County line and Waterloo. That section of SR 427 was decommissioned soon after the completion of the section of I-69 that parallels that stretch of old SR 427.
