Michigan is resurveying its 110-mile border with Indiana due to outdated maps and missing markers, aiming to prevent future disputes.

The 110-mile border between Michigan and Indiana remains undefined due to outdated 1827 surveys and decayed markers, prompting Michigan to launch a resurvey effort in 2022 with $500,000 in funding. Though Indiana supports cooperation, no private firms submitted bids, leading Michigan to consider assigning the work to local county surveyors. A 2024 survey found at least 100 missing markers and 10 potential conflict zones. State Sen. Jonathan Lindsey introduced legislation to extend the project deadline to 2030 and divide the work among five border counties to prevent future confusion, especially in communities like Ray where homes straddle the line. Officials emphasize the resurvey is a preventive measure to ensure clarity and maintain interstate goodwill.
