Bridge Length: 45 m (148 ft)

Width: 26.6 m (87 ft) 

The bridge’s maximum span length is 45 m (148 ft), and the superstructure consists of four composite steel-concrete box girders with a transversely post-tensioned top slab. The bridge is subject to high seismic loads, with peak rock acceleration of 0.30g.

The foundations consist of 1.5 m (4.9 ft) diameter steel piles partially filled with concrete with a maximum length of 45 m (148 ft). The bridge was launched from the abutment in two halves using a temporary steel nose. The concrete deck was poured at the abutment before launching. This construction method proved to be economical due to the lack of heavy cranes on the island.

It also eliminated the need for temporary supports in the waterway and construction of the concrete top slab above water. The steel pipes for the piles and the steel girders were manufactured in Mexico and delivered to the site by barge.
