Hello. There is some construction to potentially plan for **IF** it goes beyond it's scheduled end date.
On the south side of Indianapolis, there will be a closure of part of I-465 Westbound. See image below.
The construction is scheduled to finish by July 29. So if that works out, then this should NOT be a problem for any of us.
But... that's the Saturday before the Con. What if construction goes long? Then you'll want to plan for it if you'll be affected by it.
Who's affected? Drivers on I-65 North or South who want to exit onto I-465 West.
What's the detour: I-70 West.
If you're on I-65 North coming up from, say, Louisville or further south, then you'll have to go past I-465 and keep going north to I-70.
If you're on I-65 South going from downtown, then you'll have to turn around and head back up to I-70. You won't be able to exit West. Or don't head down that far to begin with; just take I-70 west from downtown from the start.
Can I-65 drivers exit to I-465 East? From what I'm reading, yes. That's not closed.
Again: Look at the map. It makes everything much more clear than text explanations.
