This is a tied-arch bridge comprising five tubular steel arches[5] mounted on six concrete foundations. The total width is 23 metres (75 ft)[5] with a span of 1,396.98 metres (4,583.3 ft). It is a two-way bridge with each direction having two lanes for cars and trucks. The two directions of traffic are separated by a steel pipe mounted approximately 50 cm (20 in) above the deck. There is also a lane for two-wheel vehicles and, beside that, an outermost lane for pedestrian traffic, which is raised above the deck by about 50 cm (20 in). These two lanes are separated from the main traffic roads by a concrete barrier and the points where the arches enter the deck.
