Governor Holcomb’s Next Level Connections program fully funded the project and accelerated construction by three years.
The project is expected to generate $4.1 billion in positive regional economic impact over 20 years.
Construction began in Martinsville in 2019 and will be delivered in five separate construction contracts.
The last and largest contract includes improvements and added capacity to I-465 on the southwest side of Indianapolis from approximately I-70 to I-65.
Crews will work to maintain access for residents and businesses as new traffic patterns are put in place.
