Portions of Main and Mill streets downtown will be closed this Sunday, March 9, as part of a fire and emergency services training drill. The closures will be from 1:30 until 6 p.m. Main Street will be closed from Spring Street to the Sylva Fire Department; Mill Street will be closed from Allen Street to its east intersection with Main Street. Eastbound traffic on Main will be detoured onto Spring and then use Allen Street to access Municipal Drive, returning to Main Street near the firehouse. Westbound traffic, which will be diverted near the Fire Department, will also use Municipal Drive to access the unclosed portions of Main and Mill streets. The simulation will involve all county fire departments, the Jackson County Rescue Squad, Sylva Police and the Sheriff’s Office. Crews will simulate a large fire breaking out in the former Carolina Hotel. There will be no fire lit as part of the drill; emergency vehicles will also not use sirens. Foot traffic will not be allowed in the block where that building is located. There’s also a possibility of the drill to cause some discolored water because of the high flows through the hydrants. Officials chose Sunday because it’s the least busy day downtown.
