As others have said, I-70 is your best bet going to Terre Haute. However, another little glitch in the wonderful world of Indiana road construction. On the south west side of Indy on I-465 between I-65 & I-70 will be reduced to one lane with 20 minute stoppages from 9 PM to 5 AM through Friday for bridge beam delivery and placement.

Just be aware that this will also put more traffic onto I-70.
