Ivory Coast struck a deal with financers and France's Bouygues on Monday to build the third bridge costing 227 million euros ($325 million) to ease congestion, 15 years after the project was first mooted. A new roundabout will be built on Riviera 2 to allow access to the third bridge. REUTERS/Thierry Gouegnon (IVORY COAST - Tags: BUSINESS CONSTRUCTION TRANSPORT)
