Jasper, Tennessee – Drivers planning to travel along Interstate 24 in Marion County should prepare for delays as a new round of maintenance work is set to begin. The Tennessee Department of Transportation has announced that contract crews will carry out vegetation removal along both eastbound and westbound lanes, a process that will require repeated nighttime lane closures over several months.
The work started on Sunday, March 29, 2026, and will affect a large stretch of roadway between mile marker 140.6 and mile marker 166.4. Officials say the left lane in both directions will be closed during the work periods, which are set to take place overnight.
Nightly lane closures expected for months
Closures will occur from Sunday through Thursday nights, with work crews active between 7:00 p.m. and 6:00 a.m. Central Time. This schedule is designed to reduce daytime disruption, but drivers should still expect noticeable slowdowns and possible congestion during these nighttime hours.
The vegetation removal effort is expected to continue for several months, with completion anticipated on or before June 30, 2026. During this time, signs will be placed along the roadway to help guide drivers safely through the work zone.
Transportation officials are urging motorists to remain alert and cautious when traveling through the affected area. Reduced lane availability combined with ongoing work activity may lead to sudden slowdowns, and drivers are encouraged to plan ahead to avoid unnecessary delays.
The project is also dependent on weather conditions. If rain or other unexpected issues arise, the schedule could shift, and work may be postponed and rescheduled for a later time.
Drivers are reminded to stay informed before heading out. TDOT encourages travelers to check current road conditions using available tools and to follow the guidance to “Know Before You Go!” by reviewing updates in advance. The TDOT SmartWay Map and the statewide 511 system are available for real-time traffic information.
Safety remains a top priority during the project. Officials are emphasizing the importance of focused driving, reminding motorists not to tweet, text, or talk on the phone while behind the wheel. In addition, Tennessee’s Move Over Law is in effect throughout the work zone. Drivers are required to move over for highway workers and emergency vehicles, and failing to do so can result in serious penalties, including up to 30 days in jail and fines of up to $500.
As the work begins, drivers are encouraged to allow extra travel time and remain patient while crews complete this necessary maintenance.
