Cowi has won a contract as owner's engineer for an eight-lane replacement immersed tunnel under the Fraser River near the Pacific coast city of Vancouver. Cowi said it will draw on its experience designing the original four-lane George Massey Tunnel in 1959 and whose removal the engineering firm will later oversee.
