Qatar-Bahrain Causeway Foundation has said a third redesign for the BD1.1bn ($2.9bn), 40km causeway linking the two Gulf countries is now in its final stages, 12 years after the project was first proposed, Gulf Daily News has reported. Plans for the 'Friendship Causeway' were announced in 2001, before being modified in 2008 to include train tracks. "The designs are in semi-final stages where 70% of them are complete," said Foundation board member, Raed Al Salah, who is also the works ministry roads projects and maintenance director. "They include the plan to have a railway connecting GCC states. However, the decision to start construction can only be made by the two governments, who firstly need to approve the final designs," he said.
