Contrack Nass JV and Sarens Nass Middle East used a self-propelled modular transporter system with 96 axles to move the bridge into place.
The tied-arch cable suspension bridge, which will carry a road and a pedestrian walkway, has a 16m-wide bridge deck of post-tensioned concrete.
The entire bridge was built an off-site facility about 250m away from the permanent location across Prince Khalifa Bin Salman Highway.
Contrack International CEO Wahid Hakki said: “This will remain a landmark design-build project in the history of bridge construction in Middle East, and we are proud to have lent our experience with accelerated bridge construction techniques to help set a new standard of efficiency for transportation projects in Bahrain. In future, conventional bridge construction methods could be replaced with the SPMT technology to reduce traffic interruptions from months to few hours at bridge construction projects.”
Sarens Nass Middle East managing director Sami Nass said that the project was challenging because of the engineering aspects involved in the movement and jacking process. “Every millimeter of precision on the move is important to ensure safety of the bridge," he said.
The project team also includes Tony Gee & Partners, Cleveland Bridge & Engineering Middle East, Mekano4 MK4, Redealli, VSL Middle East, Nass Mechanical Contracting and RMD Kwikform.
