The city of Tipp City is looking for conceptual designs for improving the Interstate 75 interchange at Exit 68.

City Manager Tim Eggleston said goals for the improvements include finding something that is as maintenance free as possible. An outline of design considerations for use in the concepts was sent recently to a number of landscape design companies, he said.

Improving the aesthetics of the interchange has been among top priorities of the city council.

The concept designs will be reviewed by a committee before presentation to council, Eggleston said.
