This application provides a passageway and a boarding bridge, wherein the passageway is disposed on the boarding bridge and includes an outer passageway and an inner passageway disposed inside the outer passageway. The inner passageway is capable of telescopic movement relative to the outer passageway. The outer passageway includes a first sidewall and a second sidewall respectively disposed on both sides of the outer passageway, a bottom wall and at least two connecting members. The bottom wall connects to the first sidewall and the second sidewall and, together with the first sidewall, the second sidewall and the bottom wall, forms a passageway space. The at least two connecting members respectively connect the first sidewall, the second sidewall and the bottom wall. The connecting members include a limiting part and a supporting part. The limiting part is used to limit the position of the inner passageway between the first sidewall and the second sidewall, and the supporting part is used to support the inner passageway. The projection of the connecting member on a plane perpendicular to the length direction of the passageway is "L" shaped.
