We've used this but not lately. I have no idea if there is any construction on this route. You'll want exit 222 (new number) off of I-69. It's a diamond shaped exit with a stop light at the top. When getting back on I-65 south at Hwy 50 in Seymour it will be a cloverleaf so you'll pass under the interstate to access the ramp on the right.
Just south of Pendleton, 1st stop light south of the High School on the left heading south, Hwy 9 makes a left turn that would be easy to miss if not paying attention.
Greenfield is straight through with the usual stop lights.
Shelbyville has a circle, If in any RV I would follow the marked truck route. It uses I-74 south for 1 exit to Hwy 44 west back to Hwy 9. It's a bit longer but takes the circle out of play for RV's.
