Soaring over a 300-meter-wide, 40-m-deep canyon, the Chavon River Bridge provides a vital link in the 70-km-long Autopista del Coral project to link Punta Cana and La Romana.

A multinational team collaborated on an innovative method of sliding 1,100-tonne, 303-m-long bridge sections across the gap with hydraulic jacks, concrete cradles and Teflon plates. To compensate for extreme seismic conditions and layers of weak soils, the team designed 1.85-m-diameter piles up to 60 m long, stabilized with polymers instead of bentonite slurry for increased safety and environmental friendliness.
