A section of Interstate 81 southbound remains closed in the Town of Watertown following a serious multi-vehicle crash that has disrupted traffic in the area.
Officials say the closure currently extends from Arsenal Street to Exit 43 (Watertown Center), creating significant congestion for commuters and travelers passing through Watertown. Emergency crews, including police, fire personnel, and medical responders, are actively working at the scene to manage the situation and clear the roadway.
While authorities have not yet confirmed the number of vehicles involved or whether there are any injuries, the presence of multiple responders suggests a complex incident. Drivers in the area are urged to avoid the affected stretch of highway, use alternate routes, and allow extra travel time.
Traffic backups have been reported along nearby roads as vehicles are being diverted off the interstate. Local officials are asking motorists to remain patient, follow posted detours, and exercise caution when traveling near the scene, as conditions may change quickly.
The cause of the crash is still under investigation, and it is unclear when the southbound lanes of Interstate 81 will fully reopen. Updates are expected as authorities gather more information and continue their response efforts.
