Nighttime I-465 lane closures and 20-minute closures

INDIANAPOLIS (Aug. 20, 2021) – The first of two long-term bridge closures in southern Marion County is scheduled to begin.

The South Keystone Avenue bridge over I-465 is scheduled to close Aug. 29, and is expected to remain closed for about four months. The detour will follow Thompson Road, Madison Avenue, Shelby Street and Hanna Avenue.

The existing South Keystone Avenue and Mooresville Road Bypass bridges will be demolished and fully reconstructed during the extended closures. The Mooresville Road Bypass bridge is expected to close in September and will be closed for about three months.

Safely demolishing the bridge spans over I-465 will require lane closures, which will occur at night to minimize traffic impacts. Demolition is scheduled to begin Monday night with the South Keystone Avenue spans over I-465 westbound before progressing over I-465 eastbound. No demolition work will happen over live traffic.

One lane of I-465 may be closed starting at 9 p.m. each night as weather permits, and the middle lane may be closed starting at 11 p.m. One lane of I-465 will remain open with 20-minute closures between I-65 and U.S. 31/East Street. Traffic backups will be given time to clear between stoppages, and all lanes are expected to reopen before the morning commute.

Temporary concrete barriers will also be installed to close the inside and outside shoulders of I-465 shoulders near South Keystone Avenue for construction.

Mooresville Road Bypass

Similar traffic patterns are expected to begin in September for the replacement of the Mooresville Road Bypass bridge over I-465. The detour for this closure will follow High School Road, Thompson Road, and Mann Road.
