The I-65/I-70 North Split interchange was completely reconstructed for the first time since 1976.
The interchange has a smaller footprint than the previous interchange, and no new right of way was required.
The new 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 have been eliminated:
- I-70 traffic from the east no longer has access to the Pennsylvania Street exit ramp. All other I-70 movements are available.
- The Delaware Street entrance ramp traffic can access I-70 East, but no longer has access to I-65 South or the collector-distributor (C-D) road serving North Street, Michigan Street, Ohio Street and Fletcher Avenue.
