The Indiana-Michigan Boundary Line Commission plans to seek quotes for survey work for the first 20 miles of the border.
The exact location of the 105-mile border has been anyone's guess for the better part of two centuries. The only government-recognized boundary is based off wooden stakes driven into the ground in 1827, but most of those have disappeared.
The South Bend Tribune reports surveyors from five Indiana counties and five Michigan counties will begin resurveying the border and marking it with cement and metal monuments.
The work is scheduled to be done by July 2018.
