Motorists should be aware of and prepare for changing traffic patterns on the southwest side of Indianapolis this weekend.

Traffic flow on southbound to eastbound I-465 between I-70 and I-65 on the city’s southwest side will be limited to a single lane beginning at 8 p.m. on Friday, March 31, lasting until 5 a.m. on Monday, April 3.

During the double-lane restriction, the speed limit on both eastbound and westbound I-465 will be 45 miles per hour. Motorists are encouraged to slow down, pay attention to changing conditions and drive distraction-free.

Watch this short video that shows where roadways and ramps are restricted during this weekend’s work. A graphic representation of the same information can be found here.

To reduce traffic volume and the number of conflict points in the construction zone, several eastbound entrance ramps onto I-465 will close during this weekend’s lane restrictions. Starting Friday at 8 p.m. the following ramps will be closed:

• I-70 eastbound to I-465 southbound
• S.R. 67/Kentucky Ave. to I-465 eastbound
• Mann Rd. to I-465 eastbound
• S.R. 37/Harding St. to I-465 eastbound

While eastbound I-465 is restricted, I-70 eastbound traffic will be detoured east to I-65 southbound at the South Split. The U.S. 31 southbound to I-465 westbound ramp  will remain closed through 2024. All other ramps will reopen by 5 a.m. on Monday, April 3.

Motorists should expect increased congestion during the weekend due to these restrictions and are encouraged to plan ahead and find alternate routes.
