Main article: Transport in Nigeria
Nigeria's publicly owned transportation infrastructure is a major constraint to economic development. Principal ports are at Lagos (Apapa and Tin Can Island), Port Harcourt, and Calabar. Docking fees for freighters are among the highest in the world. Of the 80,500 kilometers (50,000 mi.) of roads, more than 15,000 kilometers (10,000 mi.) are officially paved, but many remain in poor shape. Extensive road repairs and new construction activities are gradually being implemented as state governments, in particular, spend their portions of enhanced government revenue allocations.
The government implementation of 100% destination inspection of all goods entering Nigeria has resulted in long delays in clearing goods for importers and created new sources of corruption, since the ports lack adequate facilities to carry out the inspection. Four of Nigeria's airports—Lagos, Kano, Port Harcourt and Abuja—currently receive international flights.
Government-owned Nigeria Airways ceased operations in December 2002. Virgin Nigeria Airways started operations in 2005 as a replacement and serves domestic and international routes. There are several domestic private Nigerian carriers, and air service among Nigeria's cities is generally dependable. The maintenance culture of Nigeria's domestic airlines is not up to internationally accepted standards.
