By Staff report

On or after April 27, motorists can expect the following restrictions on Interstate 74 between mile markers 122 and 128 near St. Paul (Exit 123) through early July, weather permitting:

Eastbound I-74 traffic will be reduced to one lane and shifted to the right lane of eastbound I-74
Westbound I-74 traffic will be reduced to one lane and shifted to the left lane of eastbound I-74
All westbound I-74 lanes will be closed (traffic shifted to eastbound I-74)

The construction speed limit will be 55 mph.

This project is meant to address pavement, bridge, and lighting needs on I-74 in Shelby and Decatur counties. Construction began on I-74 between State Road 9 and State Road 3 in the spring and is set to run through 2028. It includes full-depth and partial-depth pavement patching, along with resurfacing.

Seven bridge deck overlays are planned, along with a bridge replacement at County Road 100 W. in Decatur County.

New lighting is planned at the Shelby/Decatur County line (Exit 123) to increase safety and visibility.

This project is one of four locations selected for Indiana's worksite speed control pilot program, known as Safe Zones.
