The I-65/I-70 North Split interchange was built nearly 50 years ago, is operating at full capacity and is at the end of its useful life. This is the first project to completely reconstruct the interchange, bridges and pavement along the North Split since it was built in 1968.
The interchange will have a smaller footprint than the existing interchange when construction is complete, and no new right of way will be required.
The redesigned interchange will improve safety by eliminating the weaving sections (locations where traffic is forced to cross paths) on the west leg of the interchange near the Pennsylvania and Delaware Street ramps. Eliminating the weaves will also remove the most severe bottlenecks in the interchange, allowing for improved traffic flow without adding new through lanes.
To reduce the impact of the project on adjacent historic neighborhoods, two movements will be eliminated:
- I-70 traffic from the east would no longer have access to the Pennsylvania Street exit ramp. All other I-70 movements would continue to be available.
- The Delaware Street entrance ramp traffic could access I-70 East, but would no longer have access to I-65 South or the collector-distributor (C-D) road serving North Street, Michigan Street, Ohio Street and Fletcher Avenue.
All southbound I-65 movements (Meridian Street exit, I-70 eastbound, I-65 southbound and the C-D to North Street, Michigan Street, Ohio Street and Fletcher Avenue) will be available once construction is complete.
