The North Split will close in May for 18 months. Here's what that means for your commute.

INDIANAPOLIS — Ready or not, the North Split closure is coming.

The state's second-busiest interchange located on the north side of downtown will close for 18 months around May 15, depending on weather, the Indiana Department of Transportation announced.

Interstates 65 and 70 will be closed to all traffic between the North Split and Washington Street throughout the project.

Drivers will still have access in and out of downtown via the I-70 westbound ramp to Michigan or Ohio Streets, and the Pine Street entrance ramp to I-70 eastbound.

The $350 million North Split project began in December and will continue through the end of 2022.
