Sitra Causeway Bridges, Bahrain
Gamuda Berhad took on the job of replacing the bridges and causeway between Manama (the capital of Bahrain) and the Nabih Saleh and Sitra Islands – which were more than 30 years old.
With a total length of 2.4km, and comprising the 200m Northern Bridge and 400m Southern Bridge, the four-lane dual carriageway supports the country’s rapidly growing economy, and is designed for a lifespan of up to 120 years under tough marine conditions.
Gamuda was tasked with upgrading more than 30 years old bridges and causeway between Manama (the capital of Bahrain) and the Nabih Saleh and Sitra Islands.
With a total length of 2.4km, comprising of 200m northern bridge and 400m southern bridge, the new four-lane dual carriageway system supports the country’s rapidly growing economy, and is designed for a lifespan of up to 120 years under tough marine conditions.
Gamuda encountered several challenges whilst constructing the causeway and bridge. The old Sitra Bridge was still facilitating movements of cars and trucks until the completion of the new bridges, so construction had to take place alongside existing structures. Gamuda also had to facilitate the removal of six metre silt deposits which were not initially identified by the design consultant or shown in the construction drawings, as well as navigating the numerous utilities buried beneath the junction linking Manama into the bridges.
The causeway is now one of the most strategic road links in Bahrain, providing the main link between the capital and the nearby islands.
