Many modern pedestrian bridges have been designed to attract tourist. They have multicolor lights, some have fountains and some even have fire features. They are built for the purpose of pedestrian traffic but they are also built to be a tourist attraction.
The Thê Húc Bridge is a small bridge built with a simple design for one single purpose, to enable people to have access to Ngọc Sơn Temple. Even though it was built only for pedestrian traffic, it has become a tourist attraction.
I can’t say why other people find it appealing but I find it attracting because its architectural style is unique to any other bridge that I have seen and its bright vermillion color makes the bridge stand out both during the day and at night.
