Construct grade-separated interchanges at New Ulm (CR 37) and at Courtland (on the bypass with an extension of CR 24 and a realignment of CR 12)
Construct J-Turns or Green-Ts (acceleration lanes) at higher risk at-grade intersections, including:
New Ulm Quartzite Quarries
Jeremy Drive/Kohn Drive (residential neighborhood)
