•I-10 from Lafayette to Texas will remain open
•Baton Rouge to New Orleans US 61 will remain open
•I-55 from I-12 to Mississippi will remain open

In the case that these main arteries begin to ice over, the National Guard will be staged with graders in Lafayette and Hammond to plow the roadways.

In addition to the above listed highways, DOTD is focused on keeping the following bridges open:

•Sunshine Bridge
