Transport in Senegal
This article describes the system of transport in Senegal, both public and private. This system comprises roads (both paved and unpaved), rail transport, water transport, and air transportation. Roads. The system of roads in Senegal is extensive by West African standards, with paved roads reaching each corner of the country and all major towns. International highways. Dakar is the endpoint of three routes in the Trans-African Highway network. These are as follows: Senegal's road network links closely with those of the Gambia, since the shortest route between south-western districts on the one hand and  west-central and north-western districts on the other is through the Gambia. Motorways. The only operational motorway in Senegal currently runs for 34 km. between Dakar and Diamniadio, and it is a toll motorway. A new part of the motorway, of 16.5 km. is currently under construction, which will reach the Blaise Diagne International Airport. Another section of 50 km. is also under construction, linking the airport to Thiès; and the 115 km. stretch from Thiès to Touba, the final destination of the planned motorway, will start under construction in the near future. National roads. The most important roads  in Senegal are prefixed "N" and numbered from 1 to 7: Railways. "total:" 906 km "narrow gauge:" 906 km of gauge (70 km double track) Ground transport. There were an estimated 4,271 km of paved roads and 10,305 km of unpaved roads as of 1996. Taxis (black-yellow or blue-yellow in color) are cheap, numerous and available everywhere in Dakar. It is customary to negotiate the fare since most meters installed in the taxis are broken or missing. For travel outside Dakar, public transportation is available but often unreliable and uncomfortable. Waterways. 897 km total; 785 km on the  Senegal river, and 112 km on the Saloum River. Ports and harbours. Dakar has one of the largest deep-water seaports along the West African coast. Its deep-draft structure and access channel allows round-the-clock access to the port. Its current infrastructure includes tanker vessel loading and unloading terminals, a container terminal with a storage capacity of 3000 20-foot-equivalent units, a cereals and fishing port, a dedicated phosphate terminal and a privately run ship repair facility. The port's location at the extreme western point of Africa, at the crossroad of the major sea-lanes linking  Europe to South America, makes it a natural port of call for shipping companies. Total freight traffic averages 10 million metric tons. Airports. There were an estimated 20 airports in 1999. Blaise Diagne International Airport in Diass became the hub of the sub-region. Dakar is linked to numerous African cities by air, and daily flights go to Europe. Delta Air Lines flies daily to/from Atlanta/Dakar/Johannesburg. South African Airways flies daily to New York and Washington, D.C. from Johannesburg via Dakar. The old Léopold Sédar Senghor International Airport in Dakar is now only exists as a cargo  hub.
