Before August 2015, the canal was too narrow for free two-way traffic, so ships would pass in convoys and use bypasses. The bypasses were out of (40%). From north to south, they are Port Said bypass (entrances) , Ballah bypass &amp; anchorage , Timsah bypass , and the Deversoir bypass (northern end of the Great Bitter Lake) . The bypasses were completed in 1980.
