Project Overview

Project Overview

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. INDOT reconstructed the mainline pavement between the North and South splits – dubbed HyperFix – in 2003. Other projects near the North Split addressed specific ramps or bridges that needed immediate repair. This is the first project to completely reconstruct the interchange, bridges and pavement along the North Split since it was built in 1968.

The North Split Project will replace or repair deteriorating bridges, upgrade pavement conditions in the area, reduce congestion and improve safety at the I-65 and I-70 interchange on the northeast side of downtown Indianapolis.

PREFERRED ALTERNATIVE 4c

The preferred alternative for the North Split is a refined version of Alternative 4c, which was identified and defined in the Alternatives Screening Report in September 2018. Refinements were made in late 2018 and early 2019 based on stakeholder input and more detailed engineering.

The preferred alternative meets the identified needs of the project by replacing deteriorated pavement and bridges, eliminating the most severe safety problems and improving traffic flow through the interchange. The interchange will have a smaller footprint than the existing interchange when construction is complete, and no new right of way will be required.

NEED FOR PROJECT

Improvements must be made in the next several years to repair the deteriorating bridges and pavement. During this process it may also be feasible to address some of the factors that contributed to over 1,600 accidents in the interchange between 2012 and 2016. This work is critical and should proceed as quickly as possible to address:

  • Safety
  • Deteriorated condition of bridges
  • Deteriorated condition of pavement
  • Interchange operations
  • Congestion
