Proposed New Control Points for Indianapolis:
I-70W: Terre Haute, St. Louis, Rocky Mountains
I-70E: Richmond, Dayton, Baltimore, Atlantic Ocean
I-74E: Rushville, Cincinnati
I-74W: Crawfordsville, Quad Cities
I-65N: Lafayette, The Region, Chicago, Great Lakes
I-65S: Columbus IN, Louisville, Nashville, Gulf of Mexico
I-69N: Anderson, Fort Wayne, Canada
I-69S: Bloomington, Evansville, Mississippi Delta
I assume you mean Shelbyville or Greensburg for I-74E? Rushville is 15 miles off of I-74, and considerably smaller than both of the other two, which are both located along I-74.
INDOT is a strange one when it comes to controls. They have left Indianapolis and or Bloomington off the northbound signs on I-69 fromm Evansville north. The completed interstate currently gets you within 20 miles of I-465, dumping straight into a 4-lane state-route heading straight towards Indianapolis. As mentioned, St. Louis is used for an interstate that kind of points you in the direction of St. Louis, yet ends over 100 miles away, and requires two additional interstate routes to reach St. Louis.
INDOT also doesn't use Evansville for I-64, yet Illinois does. Evansville should be the control on I-64 between Louisville and St Louis, considering its size, and junction with another interstate route, as well as a major US Highway.
