Contractors for the Indiana Department of Transportation (INDOT) plan to set bridge beams this week for a new flyover ramp being constructed at the south side Operation Indy Commute I-465 and I-65 interchange improvement project.

For the safety of motorists and workers, installation of the bridge beams will require overnight closures of the existing westbound I-465 to southbound I-65 loop ramp beginning Monday night. The ramp closure is expected to repeat Tuesday, Wednesday and Friday nights from 9 p.m. to 6 a.m.

During the overnight closures, ramp traffic will be directed to continue westbound on I-465 to State Road 37/Harding Street (Exit 4) and return eastbound on I-465 to access southbound I-65.

Once the project is complete, the new flyover ramp will replace the existing single-lane loop ramp on the northwest side of the interchange, increasing capacity and improving flow by carrying two lanes of traffic from westbound I-465 over I-465 to southbound I-65. The $40 million project is adding auxiliary lanes along I-65 to connect between the I-465 and Southport Road interchange ramps. Auxiliary lanes are also being constructed on I-465 between I-65 and Emerson Avenue.

Sherman Drive remains closed until approximately Sept. 1 as the bridge over I-465 is reconstructed and lengthened to accommodate widening I-465 below.
