Carson Ave. to close at I-465 for bridge replacement

INDIANAPOLIS – Bridge replacement work is scheduled to close Carson Avenue at I-465 on Sunday, July 24, and is expected to last about six months with a detour that will follow Keystone Avenue and Thompson Road. 

I-465 traffic should expect nighttime lane closures and intermittent 20-minute traffic stoppages near Carson Avenue. Demolition of the bridge will require nighttime closures and detours for two nearby ramps between 11 p.m. and 5 a.m.:

  • The I-465 eastbound ramp to I-65 southbound
  • The I-65 southbound ramp to I-465 westbound

Carson Avenue is the fifth and final bridge that the I-69 Finish Line project is replacing over I-465 to allow added lanes underneath. The new Madison Avenue overpass fully opened to four lanes and sidewalks earlier this week, and work is ongoing to replace the Mann Road bridge. The Mooresville Road Bypass and Keystone Avenue bridges were previously replaced and reopened on schedule.
