As a result of the cyclone “Gonu” in June 2007, many roads and culverts were washed away in Sultanate of Oman. Gonu is considered the strongest tropical cyclone on record in the Arabian Sea. The impact was highest in the coastal areas and some regions were completely cut off for a number of days.The Omani Ministry of Transport and Communication took a big step in initiating the building of new bridges and the rehabilitation of existing ones. Furthermore, many culverts are now being upgraded to bridges. This was especially important in the areas most devastated during the cyclone. The Sur – Al Ayjah Road connects Al Ayjah town with the city of Sur across the creek. The bridge is built from precast, post-tensioned T-girders with integral piers and a continuous deck slab.
