Evacuation lanes are designated emergency shoulders along hurricane evacuation routes that can be temporarily converted into travel lanes to increase capacity during an evacuation event. These shoulders may also be referred to as "EvacuLanes" and are typically wider than a traditional shoulder.

When determining the EvacuLane width, designers should consider bridges and any adjacent railings or barriers along the edge of the shoulder.

The recommended minimum width for an EvacuLane is 12-ft
