Major portions of Grant Mountain Road were deemed impassable, according to the Marshall County Sheriff’s Office.

Morgan County

Law enforcement officials, including the Morgan County Sheriff’s Office (MCSO) and the Alabama Law Enforcement Agency (ALEA), say the following roadways are closed, impassable, or should be used only with extreme caution:

• The interstate and the Tennessee River Bridge traffic is flowing.

• Hudson Memorial Bridge is moving without issue.

• Apple Grove Road in Union Hill near Brewer High School (open, but use caution)

• Highway 36 in Lacey’s Spring has improved and traffic is flowing cautiously.

• U.S. Highway 231 still has icy patches, but traffic is flowing.

• The problem areas that remain are the secondary roads, which may be impassable.

The Morgan County EMA had this to say:

“Roadway is clear and moving. Got word that 231 from Morgan City to Apple Grove road is still solid ice. There [are] several cars and trucks pulled over on the sides of the road. Use caution in this area. ALDOT only salted the mountain portion of 231.”

Drivers are asked to avoid these areas if at all possible and to use extreme caution if forced to drive in the areas.
