... along northwest Indiana highways, as IN-DOT's annual mowing operations begin across the Region. The Indiana Department of Transportation says grass along the right-of-way grows longer than grass in your yard -- with thousands of acres to maintain, INDOT says it's not possible to maintain the medians like a typical lawn. INDOT is working to reduce the need to mow at all by expanding their Roadside Heritage Program, which uses wildflowers and native plants to landscape Hoosier roadsides. INDOT generally mows along interstates, state roads and U.S. Routes three times a year but the Borman (I-80/94) and State Road 912 (Cline Ave) are on a five-cycle process.
