Official opening of the Four Bears Bridge in North Dakota is set for 3 October. The ceremony will also mark the 50th anniversary of the original bridge's dedication. The new 1,370m-long bridge over Lake Sakakawea is being built by Fru-Con Construction at a cost of US$55.4 million, making it the state's largest-ever bridge contract. The original bridge will be demolished once the new crossing is in use.
