| Abstrait: |
The A1-M1 Link Road is a 1 km highway project, currently under construction in Mauritius. The project will cross the Grand River North West Valley, a 90 m deep gorge, with a 3-span extradosed bridge. The island of Mauritius is subject to major cyclonic winds and the gorge being crossed needed to be adequately accounted for when assessing the wind effect on the bridge. A detailed wind climate study of the project site was conducted to derive wind buffeting loads for the design of the bridge. In addition, particular geotechnical stability issues encountered at the cliffs on either side of the gorge, dictated a non-optimum span distribution which required a complex arrangement of temporary stay cables. When complete, the bridge will be a key component of the A1-M1 Link Road Project and will link the existing A1 Road and M1 Motorway, improving connectivity on the West Coast of the Island. |
