Originally, it was an unnamed wooden bridge. In 1899, it was rebuilt as an elegant steel-structured bridge, with fortress-like structures on both sides resembling gate passages, though without actual doors like those of other [[Fortifications of Bangkok|city gates of Rattanakosin]]. As a result, the area came to be known as "Pratu Mai" (ประตูใหม่, {{lit|new gate}}).

Originally, it was an unnamed wooden bridge. In 1899, it was rebuilt as an elegant steel-structured bridge, while the bridge deck remained wooden and was equipped with rollers underneath, allowing it to be [[Submersible bridge|opened and closed]] to let boats pass, with fortress-like structures on both sides resembling gate passages, though without actual doors like those of other [[Fortifications of Bangkok|city gates of Rattanakosin]]. As a result, the area came to be known as "Pratu Mai" (ประตูใหม่, {{lit|new gate}}).
