The main cable-stayed bridge consists of a span of 183 m (600 ft) in length and side spans of 30 m(98 ft) and 73 m (240 ft). Two planes of stay cables in a “harp” arrangement support the steel-concrete composite superstructure. The concrete pylons rest on concrete pile caps at water level, supported by 1.5-m (4.9-ft)-diameter bored piles.
