The article talks about how pedestrian bridges in Japan have evolved over the years to enhance the city environment. In the late 1970s, designers started building pedestrian bridges like the Hasune Crossover Bridge to improve the look of cities. New trends in bridge design emerged in New Towns, where pedestrian and vehicle traffic were separated. Pedestrian decks were introduced in the 1980s, and bridges started incorporating structural entertainment and visual elements. The design of pedestrian bridges in the planned extension area of Tama New Town took a new approach to fit into the urban space better.
