The Louisiana Department of Transportation and Development has released a list of roads previously closed due to the blizzard that have reopened.

The latest closure means that nearly three-quarters of Louisiana’s portion of the coast-to-coast highway is shut. A rare winter storm brought record snowfall to the state on Tuesday.

Interstate 10 from the Louisiana-Texas state line to as far east as Sorrento or Gramercy could be fully open to traffic in both directions at some point Thursday afternoon, Department of Transportation and Development Secretary Joe Donahue said.

Interstate 10 in the Baton Rouge metro area reopened to both eastbound and westbound traffic Thursday afternoon, the Department of Transportation and Development announced.

Forecasters are also becoming increasingly confident that some kind of frozen precipitation— whether its snow, sleet or freezing rain — will impact South Louisiana.

Louisiana Governor Jeff Landry said the state is facing potential record snowfall that could close Mississippi River bridges from Baton Rouge to New Orleans.

A winter storm swept across south Louisiana on Tuesday morning, covering New Orleans, Baton Rouge and Lafayette in a layer of snow.

Louisiana Gov. Jeff Landry and state officials held a news briefing on Wednesday to update residents on the unprecedented weather event and its ongoing challenges.

Local restaurants and grocery stores are gradually resuming normal hours, but residents are encouraged to check social media pages for updated schedules.

A rare winter storm buried the Deep South in a blanket of snow on Tuesday. Parts of South Louisiana, Texas and Mississippi saw more than 9 inches of snow on the ground, according to preliminary estimates from the National Weather Service.

Baton Rouge is under an extreme cold warning until 10 a.m. Wednesday, the National Weather Service said. The high today is expected to be 31 degrees, with a low of 16 degrees.
