Abstract: Urban historical transportation serves as the spatial framework of urban evolution and a carrier of collective memory. Current research on the preservation and revitalization of intra-urban historical transportation remains limited， and existing conservation efforts often failing to integrate transport routes with the renewal of adjacent spaces. Against this backdrop， this study introduces the heritage corridor theory to propose a corridor-based revitalization model for urban historical transportation， using Dalian’s well-preserved tram line as a case study for empirical conservation research. Through this investigation， this paper presents an integrated development strategy featuring “one line with one hub，” “one line with five cores，” and “one line with three segments，” together with supporting systems such as a roaming framework and an interpretive system， aiming to facilitate the transformation of Dalian’s tram line into a heritage corridor. This also reveals the core essence of constructing urban transportation heritage corridors： reestablishing the connections between historical transportation systems and their adjacent cultural spaces through aspects such as layout， function， narrative， and landscape. Through empirical and theoretical research， we hope to transcend individual cases and provide insights for the revitalization of more urban transportation heritage sites.
