The design of the bridge comprises two parallel spans, each with a width of 16.5m and a distance of 11.8m between them. The unique feature of this bridge is the pedestrian bridge and observation deck situated between the two spans, with a width of 7.9m and a landscape architectural scale of approximately 163.84m².

Previously, in late 2023, the People’s Committee of Ninh Binh City (now Hoa Lu) proposed a bold idea to build a “water bridge,” inspired by the Veluwemeer Water Bridge in the Netherlands, at the same location. A water bridge is a unique type of transportation infrastructure where a water channel crosses over a road, creating a striking landscape and tourism attraction.

This proposal included a request for a provincial budget support of 130 billion VND to implement a synchronized technical infrastructure system for the project. However, after consideration, the Department of Planning and Investment (now the Department of Finance) along with related units reported to the Provincial People’s Committee about the technical, financial, and construction condition obstacles at the Trang An – Le Thai To intersection.

The provincial leaders of Ninh Binh acknowledged that while the water bridge, if realized, would become a new symbol of Ninh Binh’s tourism, allowing tourist boats to glide on the water above while vehicles pass underneath, the technical challenges, high construction costs, and specific geographical and geological requirements made this option unfeasible.

Although many locals expressed disappointment at the inability to materialize the one-of-a-kind water bridge idea, the choice to go with a solid bridge that includes an observation deck combined with a pedestrian bridge strikes a balance between technical factors, economic considerations, and symbolic value, adding a new scenic highlight to the Trang An – Hoa Lu heritage area.
