Objective: The revitalization of the Kayutangan Corridor has changed the physical condition of the sidewalk and made the corridor more attractive for pedestrians. However, a better sidewalk does not automatically mean that the corridor functions as a social space. The main issue is whether people use the revitalized corridor as a place to stay, gather, interact, and spend time, rather than only as a route. This study describes how social space is formed in the Kayutangan Corridor. Design/Methods/Approach: The research used a qualitative method. Behavior mapping was used to observe activities across four segments on weekdays and weekends. The study included 881 participants and focused on their age, group, length of stay, and activity. Findings: The results show a clear temporal pattern of social activity, with peaks on weekend nights. On weekends, especially at night, segments 2 and 3 function as the main social space where people stay longer and visit in groups more often. In contrast, Segments 1 and 4 mostly serve as transition corridors. People of different ages also use the corridor, indicating its inclusiveness. Originality/Value: Unlike previous studies that mainly discuss physical improvement, tourism development, or street furniture in revitalized heritage corridors, this study emphasizes how temporal use, spatial setting, lingering, group presence, and activity diversity shape social space. Practical/Policy implication: These findings suggest that urban corridor revitalization should focus not only on physical improvements but also on how sidewalks can enhance lingering, social interaction, and inclusive everyday use. Thus, the sidewalk can function as a meaningful public social space.
