Project Name: US Navy Bridge Movement
Client: US Navy, Bahrain
Year: 2014

A unique bridge construction effort carried out by Nass Contracting and its JV partner had one of the most cutting edge which included: “build, lift, move and install” and is unlike any bridge installation undertaken in the Middle East.

The flyover bridge is approximately 122.5m long, 16m wide and 21.4m tall (from ground 27.5m), and is a tied arch cable suspension bridge with a roadway and pedestrian walkway.

The 16 meter wide bridge deck is a concrete post tensioned construction. The entire bridge was constructed at an offsite facility about 250 meters away from the permanent location and was moved to be placed at two end piers with highway completely open.

Known as the ‘SPMT (Self-propelled Modular Transporter) Bridge Move’, a team of experts from Sarens Nass Middle East moved this off- site manufactured bridge weighing 2650 metric tons (with lifting beam 2850 metric tons) from the assembly location to the Highway.

Nass Industrial Services was subcontracted to fabricate and erect the 2850 metric tons lifting beams to carry the bridge, and also erected all steel structures including the bridge arch.
