Closures Scheduled on US-31W to Continue DDI Configuration

Nashville, Tenn. - The Tennessee Department of Transportation (TDOT) will conduct lane closures on US-31W (State Route 41) and lane shifts from Interstate 65 in Sumner County.

Beginning at 8 p.m. on Wednesday, September 16, crews with Jones Bros. will reduce US-31W to one lane in both directions to begin the next phase of construction activities on the conversion of the interchange at US-31W and I-65 to a Diverging Diamond Interchange (DDI). US-31W in this area is expected to be down to one lane in each direction until Summer 2027. Additional lane shifts are anticipated during this time frame.

As part of this phase, crews will re-stripe the I-65 off-ramps to US-31W, prompting a lane shift from 8 p.m. to 5 a.m. on Wednesday, September 16, and Thursday, September 17.

This work is part of TDOT’s I-65 Phase 3 Widening & Improvements project, which began construction in March 2025. In addition to adding a travel lane in each direction, this work includes the reconfiguration of the I-65/US-31W interchange to a Diverging Diamond Interchange (DDI).

The DDI's unique crisscross design allows two directions of traffic to temporarily cross to opposite sides of the roadway to travel under the interstate, then cross back and resume the original travel pattern. An animation explaining the configuration can be found here.

All work is weather-dependent. As always, drivers are reminded to allow additional time, slow down, and move over when traveling through a work zone. The Move Over Law was passed in 2006. The penalty for violating the law in Tennessee includes the possibility of up to 30 days in jail and a maximum fine of $500.

Motorists can report potholes to TDOT by calling the TDOTFIX Hotline at 833-TDOTFIX or using this online form: TDOT Maintenance Request. The TDOT SmartWay Map (https://smartway.tn.gov) provides the latest traffic updates on construction activity. Travelers can also call 511 for travel information.

*US-31W is a north/south highway.
