Construction FAQs

What is the final interchange design and why was it chosen?

It is INDOT’s determination that among the alternatives that meet the project purpose and need, Alternative 4c provided the best balance of meeting safety and mobility needs while minimizing or potentially eliminating the need for retaining walls along the legs of the interchange. Alternative 4c does not include added through lanes on the interstates.

When will construction end?

The North Split is now open, but there is still work to do. Local street paving will continue until 2024.

What ramps closed permanently after construction?

  • I-70 traffic from the east will no longer have access to the Pennsylvania Street exit ramp.
  • The Delaware Street entrance ramp traffic will have no access to I-65 southbound or the collector-distributor (C-D) road serving North Street, Michigan Street, Ohio Street and Fletcher Avenue. Access from Delaware Street to I-70 eastbound will be maintained.

What improvements will be made to local streets in the project area?

The Aesthetic Design Guidelines developed during the Context Sensitive Solutions (CSS) public outreach process and the environmental study phase outlined many changes to local streets within the project area. In addition to being newer, safer and quieter, the underpasses being replaced will receive wider sidewalks and underlighting. Other improvements and renderings of the completed bridges are available here.

Where and when will noise barriers be installed?

The following potential noise barriers are recommended for construction:

  • NB3E: Westbound I-70, along the edge of the north shoulder from Valley Avenue to Commerce Avenue, near the Martindale-Brightwood neighborhood
  • NB3W: Westbound I-70, along the edge of the north shoulder from Commerce Avenue to Lewis Street, near the Martindale-Brightwood neighborhood

Construction of these noise barriers will occur after the reconstruction of the North Split interchange is substantially complete, likely in spring 2023. More information about the noise analysis is available at
