Project Overview

Project Overview

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


INDOT recently released the North Split Alternatives Screening Report, which analyzes a range of preliminary alternatives and identifies the preliminary preferred alternative to be evaluated in greater detail in the Environmental Assessment (EA). The EA is being developed to meet the requirements of the National Environmental Policy Act of 1969 (NEPA). The NEPA process for this project began by identifying project needs and scoping potential alternatives to be evaluated in the environmental study, and will continue with public involvement and further analysis into 2019 and 2020.


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
