Bridge on Arafat Rd over Al Aziziya Rd. Riyadh, Saudi Arabia

The viaduct is located at the intersection between Arafat Road and Al Azizia Road, in Riyadh, Saudi Arabia. The bridge consists of a prestressed multiple cell concrete bridge.

Total length of the bridge is 517 meters, divided in eleven spans 5x45-67-5x45 meters long each. Total width is 26.40 m.

The role of SILGA was to develop the detail design of the structure, with the peculiarity in this case that the substructure was partially build by a previous contractor. Modifications in the original design were introduced so as to minimize construction time.

SILGA provided also assistance to construction and design review of PT show drawings, bearings and expansion joints.
