1. An evacuation slide, comprising:
- a first side tube extending longitudinally between a head end and a toe end of the evacuation slide;
a second side tube extending longitudinally between the head end and the toe end of the evacuation slide;
a center tube extending longitudinally between the head end and the toe end of the evacuation slide;
an arched tube extending between the first side tube and the second side tube of the evacuation slide, the arched tube extends substantially orthogonal to the center tube, wherein the arched tube is separate from the center tube and is configured to contact the center tube in response to the evacuation slide being deployed; and
a strap coupled between the arched tube and the center tube of the evacuation slide,wherein the arched tube is configured to provide vertical support to the first side tube and to the second side tube in response to a tension in the strap.

Abstract
An evacuation slide may comprise an arched tube configured to extend between a first side tube and a second side tube of the evacuation slide and a strap configured to be coupled between the arched tube and a center tube of the evacuation slide. The arched tube may be configured to provide vertical support to the first side tube and to the second side tube in response to a tension in the strap. The evacuation slide may comprise a dual lane slide, the first side tube and the center tube defining a first lane and the second side tube and the center tube defining a second lane.
