Roads in Senegal
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:
- Cairo-Dakar Highway which crosses the edge of the Sahara
- Dakar-Ndjamena Highway which links the countries of the Sahel, also called the Trans-Sahelian Highway
- Dakar-Lagos Highway running along the West African coast and called by the Economic Community of West African States (ECOWAS) the Trans–West African Coastal Highway (though ECOWAS considers this route to start in Nouakchott, Mauritania).
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.
