The Indiana highway department said Tuesday that the project includes building a new high-speed, two-lane ramp for traffic going from eastbound I-465 onto northbound I-69. The plans also include adding ramp lanes in each direction on I-465 for its interchanges with I-69, Allisonville Road and Keystone Avenue.
Officials say the project is estimated to cost $50 million and is aimed at easing congestion and improving safety in the corridor used by more than 165,000 drivers a day.
The highway department says preliminary design work is to begin next year, with construction expected to start in 2020.
