Passageway including a section that is extendable and retractable, the section including frame, slide track assemblies, and scissor bar assembly. The frame includes upright members on a first side of the frame. The slide track assemblies are disposed proximately to the upright members. Each of the slide track assemblies includes a slide track and a slide block. The slide track has a cavity and a channel. The slide block can ascend, descend, and rotate within the cavity. The slide block includes a guide block that extends from the slide block through the channel. The scissor bar assembly is secured to the upright members and slide blocks of the slide track assemblies such that the upright members are enabled to extend and retract with respect to each other along an arcuate path, wherein the guide block limits rotation of the slide block to rotation of the guide block within the channel.
