TUPELO, Miss. (WTVA) -- The Natchez Trace Parkway is closed in some parts.

Currently, the Natchez Trace Parkway is closed from Mileposts 0 to 152, 355 to 370, and 429 to 442 because of severe weather and icy conditions. Additional closures are anticipated as the winter weather moves along the Parkway.

Chief Ranger Prashant Lotwala said roads are almost impassable in the northern and southern sections of the park and most bridges are iced over.

Drivers who slide off the roadway or wreck may have to shelter in place for an extended period of time as emergency personnel may have a delayed response during this weather event. 

The Parkway does not chemically treat the roadway in icy conditions. As the weather continues to deteriorate, trees and limbs will come down onto the Parkway.

Staff will not respond to downed trees until conditions are safe to do so.

The Parkway Visitor Center in Tupelo and Mount Locust at Milepost 15.5 are closed.
