The grant was based on an original design to build a two-bridge overpass. Original overpass design for 13th Street and 8th Avenue After the grant was approved, INDOT conducted a study to make sure the plan was feasible, coming back to the city with three possible options: Do nothing, move forward with the original plan or look into a third option that would result in a "significant cost savings," Maurer said. The third option, chosen by the city, includes a roundabout on both 13th Street and 8th Avenue with a single overpass 8th Avenue. Maurer noted the third option is also a "less intrusive design" with the shorter approaches having a "reduced impact" on the neighborhood.
