In 1967, during the Cultural Revolution, Neale Hunter, an Australian who lived in the Broadway Mansions for nine months, described the Garden Bridge as "an ugly tangle of bolted iron struts", while Red Guards renamed the bridge, "Anti-Imperialism Bridge".

In 1970 extensive sandblasting was conducted on all the steel components of the Waibaidu bridge to remove all rust.
A rust-proof zinc spray was then added to the bridge, and the sidewalk railings repainted grey, while the side safety fences were painted white.
In 1977 the Shanghai Municipal Design Institute examined and reinforced the beams of the bridge.
