In the event of a hurricane evacuation from low-lying coastal areas, existing highway lanes (freeway and non-freeway) may be converted into "contraflow lanes."

What is Contraflow?

Contraflow is when vehicles travel in the opposite direction of a lane's normal traffic flow.

This occurs during an event like a hurricane evacuation, when all traffic lanes move toward inland safety and away from the Gulf Coast.

A hurricane evacuation lane is an extra wide shoulder that is converted into an active thru lane in order to increase capacity during an emergency.
