I-465 West on southside to be reduced one lane this weekend

This weekend traffic patterns on the southwest side of Indianapolis will change to allow Interstate 69 Finish Line to enter its next phase of construction: widening and rebuilding I-465 eastbound, which will include a new bridge over the White River.

From 8 p.m. tonight through 5 a.m. on Monday, traffic on westbound Interstate 465 between Interstate 65 and Interstate 70 on the southwest side will be limited to a single lane. Crews will shift the westbound lanes to the north in preparation for an eastbound switch later in the month, according to a construction update from the Indiana Department of Transportation.

The speed limit on westbound I-465 will be reduced to 45 miles per hour, INDOT officials say.

Several westbound entrance ramps onto I-465 will close during this weekend’s lane restrictions.

Starting tonight at 8 p.m. the following ramps will be closed:

  • I-65 southbound to I-465 westbound
  • I-65 northbound to I-465 westbound
  • U.S. 31 southbound to I-465 westbound
  • U.S. 31 northbound to I-465 westbound
  • State Road 37/Harding Street southbound to I-465 westbound

The U.S. 31 southbound to I-465 westbound ramp closure will remain in place through 2024. All other ramps will reopen by 5 a.m. on Monday, INDOT officials say.

I-65 northbound traffic will be also be detoured north to I-70 westbound at the South Split. The nearest entry point to the I-465 westbound work zone is Emerson Avenue, INDOT officials say.

A similar restriction for eastbound I-465 is currently scheduled for March 24-27 but the schedule is subject to change. The most current information about closures and restrictions can be found at 511in.org or INDOT’s TrafficWise app.
