Overview

The I-65 / I-70 North Split (North Split) project will reconstruct the I-65 and I-70 interchange located in downtown Indianapolis. As one of the most heavily traveled interchanges in Indiana, many structures have exceeded their service life after nearly 50 years in operation. When complete, the North Split project will reduce congestion, improve safety for the community and travelers, and provide a maintenance-free infrastructure for decades to come. Comprised of four sections – the south leg, west leg, east leg, and interchange – this design-build project will replace all pavement, reconfigure the interchange into three levels, eliminate two ramp movements, replace numerous bridge structures, install a new drainage system, improve local streets, replace ITS facilities, and provide new aesthetic and landscape features.
