The project to extend Ameriplex Parkway to the intersection of Southport and Mann Road in southern Indianapolis is rapidly moving forward. Earlier this year, a recommended final route alignment was selected from among three alternatives. The project, now dubbed Decatur Direct, is now in the detailed design phase. Right-of-way acquisition is scheduled to get underway in 2021, with construction planned to commence in 2023.
The new roadway will feature four 11' traffic lanes, two lanes in each direction. Parts of the roadway will have a 15' raised traffic median, while other sections will not. On one side of the roadway will be a 10' multi-use path separated from the roadway by a 6' grass buffer, while the other side will have a 6' concrete sidewalk, also separated by a 6' grass buffer. To improve traffic flow, at least two traffic roundabouts are planned.
The project's main objective is to improve connectivity in southern Marion County, and to enhance access to Indianapolis International Airport and nearby areas from southern portions of Marion County as well as western sections of Johnson County.
