Construction contractors plan to close the westbound I-70 ramp to southbound I-465 on the east side of Indianapolis tonight starting at 9 p.m. until 6 a.m. on Tuesday to set temporary concrete barriers along the ramp bridge.

During the overnight ramp closure, interstate traffic will be directed to Shadeland Avenue Exit 89 to return eastbound on I-70 and access southbound I-465.

Over the next several weeks, crews will be applying a modified concrete deck overlay and replacing the concrete bridge railing. The Indiana Department of Transportation says up to two lanes of I-70 may be closed under the bridge between 9 p.m. and 6 a.m. as the work is completed.

INDOT says motorists in the area will need to pay attention to construction warning signs and abide by reduced work zone speed limits.
