It has a total length of with a main span of and approach spans of and on the north and south banks respectively. The bridge's deck is made of prefabricated concrete sections with an epoxy asphalt roadbed. It includes a 3-metre (9.8 ft) thick steel brace structure with girders at 14 metre intervals under the main deck to stiffen the bridge against the wind. The two main cables that support the deck are in diameter and each consists of 19,558 5.35 mm steel wires arranged in 154 strands. The portion of the cables over the shorter northern approach span include an additional eight strands to withstand the greater force exerted on them because of the smaller ratio in relation to the length of the main span. The north and south support towers for the main cables are and tall respectively and constructed of reinforced concrete with two
