m (1100 ft). The previous bridge was destroyed in 1967 during the Arab-Israeli conflict. The current bridge is no longer functional due to the expansion of the Suez Canal, as the parallel shipping lane completed in 2015 just east of the bridge lacks a structure spanning it. The Ahmed el-Mansy pontoon bridge (), a pair of pontoons bridging both channels The Taha Zaki Abdullah pontoon bridge (), a pair of pontoons bridging both channels Pipelines taking fresh water under the canal to Sinai, about north of Suez, at . Ahmed Hamdi Tunnel () south of the Great Bitter Lake () was built in 1983. Because of leakage problems, a new water-tight tunnel was built inside the old one from 1992 to 1995. The Ahmed Omar Shabrawy pontoon bridge () The Suez Canal overhead powerline crossing () was built in 1999. A railway on the west bank runs parallel to the canal for its entire length. The five pontoon bridges were opened between 2016 and 2019. They are designed to be movable, and can be completely rotated against the banks of the canal to allow shipping through, or else individual sections can be moved to create a narrower channel. Six new tunnels for cars and trains are also planned across the canal. Currently the Ahmed Hamdi is the only tunnel connecting Suez to the Sinai. Economic impact Economically, after its completion, the Suez Canal benefited primarily the sea trading powers of the Mediterranean countries, which now had much faster connections to the Near and Far East than the North and West European sea trading nations such as Great Britain or Germany. The main Habsburg trading port of Trieste with its direct connections to Central Europe experienced a meteoric rise at that time. The time saved in the 19th century for an assumed steamship trip to Bombay from Brindisi and Trieste was 37 days, from Genoa 32, from Marseille 31, from Bordeaux, Liverpool, London, Amsterdam and Hamburg 24 days. At that time, it was also necessary to consider whether the goods to be transported could bear the costly canal tariff. This led to a rapid growth of Mediterranean ports with their land routes to Central and Eastern Europe. According to today's information from the shipping companies, the route from Singapore to Rotterdam through the Suez Canal will be shortened by and thus by nine days compared to the route around Africa.
