CRBC erects first girder for Nairobi road upgrade project
China Road and Bridge Corporation (CRBC) erected the first 30-meter precast box girder for the KAB Bridge under Nairobi's municipal road upgrade project in Kenya on Sept 19.
It is CRBC's first precast box girder to be erected in East Africa and marks the beginning of construction on the bridge's superstructure.
The KAB Bridge is 600 meters long with 23 spans; 14 spans use precast girders, totaling 84 girders. Its maximum longitudinal gradient is 6 percent. The contractor adjusted the construction plan and reinforced the launching gantry's rear, front, and middle leg supports to complete the first erection.
The project runs through central Nairobi, passing landmarks such as the University of Nairobi and the National Museum of Kenya. Heavy traffic and the need to coordinate with multiple parties have complicated construction. Once completed, the road upgrades are expected to ease congestion, improve traffic flow and reduce travel and transportation costs.
