The Rama 8 cable-stayed bridge is one of the most recent crossings over the Chao Phraya River in Thailand. The Bridge displays excellence in engineering technology together with architectural respect for the traditions and values of Thai culture.

Rama 8 Bridge is one of the world's largest asymmetric cable-stayed bridges. It comprises a light composite steel and concrete main span balanced by cast-in-place, post-tensioned concrete box girder land spans.

The Bridge is a 475 m (1558 ft.) long structure supported by a single 160 m (525 ft.) tall inverted Y-shaped tower. The main span is 300 m (984 ft.) in length. The land span consists of two 50 m (164 ft.) back spans and a 75 m (246 ft.) anchor span.
