Operations to Prompt Traffic Shift and Speed Limit Change on State Route 52

Nashville, Tenn. – The Tennessee Department of Transportation (TDOT) will conduct a traffic shift on State Route 52 in Sumner County.

Starting Thursday, September 24, State Route (SR) 52 will experience a traffic shift, or slight relocation of travel lanes, east of Lyon Drive to near Searcy Lane for the remaining construction of a box culvert to be placed underneath SR 52. As part of the traffic shift, the posted speed limit in this area (approximately one mile) will be reduced from 40 mph to 30 mph to enhance safety through the work zone.

The traffic shift and reduced speed limit are anticipated to remain in place for approximately three months. Signage will be in place. Motorists are urged to use caution as they navigate the shift. 

This work is part of TDOT’s SR 109 Phase 1 Portland Bypass project, which began construction in August 2025. This project includes constructing a new segment of State Route 109, bypassing the City of Portland, as part of a larger effort to improve safety and mobility along the heavily traveled SR 109 corridor.

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.
