Located in the capital city of Georgetown, the bridge stretches approximately 2,900 meters with a main span of 300 meters. It’s a dual-tower, double-cable-plane prestressed concrete cable-stayed bridge that features four lanes in both directions and supports a designed speed of 80 km/h. The 300-meter main span overcame a series of challenges posed by complex local geological and environmental conditions.
Engineers applied a range of advanced technologies, including reverse circulation drilling for ultra-long pile foundations, intelligent temperature control for massive pile caps, BIM modeling, and precision hydraulic adjustment systems. These innovations ensured the high-quality completion of ultra-deep foundations and the precise closure of the main girder, establishing a refined quality management system throughout the entire lifecycle and setting a new benchmark for large-scale bridge construction in the country.
Upon opening, the bridge is expected to reduce cross-river travel time by 75 percent, double the river’s navigational capacity, and will serve as a key transport hub connecting the Atlantic Ocean with Guyana’s inland regions.
