 Prior to 2004, the interchange from the Indiana Toll Road to southbound I-65 required making a physical left turn onto I-65 via a traffic signal; traffic from northbound I-65 to I-90 bypassed the traffic signal via an isolated right-turn lane.This deficiency has since been corrected by a grade-separation.As part of the "Operation Indy Commute" project, INDOT began work in 2013 to widen I-65 on both northbound and southbound mainlines from exit 103 at Southport Road northward to the southern junction with I-465 (exit 106), adding auxiliary lanes in this section to improve merging of traffic entering southbound I-65 from I-465 and entering northbound I-65 from westbound Southport Road.
