A coastal corridor stretching roughly 600 miles from Lagos, Nigeria, to Abidjan, Ivory Coast — passing through Benin, Togo and Ghana — is expanding at a rate that urban experts say could house more than 50 million people by 2050, yet researchers and residents describe a region where rapid growth has so far produced limited broad prosperity.
A 600-mile coastal road reveals West Africa's urban transformation between Lagos and Abidjan
A coastal corridor stretching roughly 600 miles from Lagos, Nigeria, to Abidjan, Ivory Coast — passing through Benin, Togo and Ghana — is expanding at a rate that urban experts say could house more than 50 million people by 2050, yet researchers and residents describe a region where rapid growth has so far produced limited broad prosperity.
NPR spent two weeks traveling the Lagos-Abidjan corridor, documenting conditions across the five countries. The corridor is linked by a coastal road that is being gradually developed into a projected $15 billion superhighway under the leadership of the Economic Community of West African States (ECOWAS), a 12-country regional bloc intended to unlock the region's economic potential.
In Lagos, Nigeria, the Mile 2 bus station has for decades served as a gateway to the corridor, connecting cities from Benin to Ivory Coast and Burkina Faso. Drivers and transport workers there describe a decline in passenger numbers they attribute in part to a weakening of Nigeria's economy over the past decade, which they say has reduced cross-border trade in goods ranging from electronics to fabrics.
The Lagos-Badagry highway, which runs west from Lagos to the Benin border, is under reconstruction. NPR reported passing through more than 30 checkpoints over a less-than-10-mile stretch. Drivers said they are routinely required to pay officers at checkpoints staffed by immigration officials, police, soldiers, and plainclothes individuals carrying clubs. One motorist, identified as 40-year-old Peter Uche, said more than half of the roughly 40,000 naira (approximately $28) he earns per trip is spent at checkpoints. Nigerian customs and immigration officials did not respond to NPR's request for comment.
In Benin, the commercial capital Cotonou — a city of approximately 800,000 people — is undergoing significant development along a 25-mile coastal stretch to the historical city of Ouidah. New markets, restaurants, waterfront bars, coastal walkways, and a graffiti wall have been constructed. The government rebuilt the Marché de Ganhi, reopened in December 2024 as a two-story structure with hundreds of stalls.
The development in Benin occurred under former President Patrice Talon, whom some economists describe as having overseen a modest transformation of the country. Newly elected President Romuald Wadagni has said he intends to continue that trajectory. International human rights groups have, however, criticized a government clampdown on critics. Taxes on Benin's informal economy, which accounts for roughly half of GDP according to the International Monetary Fund, have drawn quiet public discontent. More than a third of Benin's estimated 15 million people still live in poverty.
Development in Cotonou has also displaced thousands of residents, particularly the city's poorest. NPR observed hundreds of beachfront structures that community members said were illegally demolished, including a clinic, in an area the government has designated for tourism development between Cotonou and Ouidah. Residents were seen searching debris and salvaging belongings. Benin's government did not respond to NPR's requests for comment on the demolitions.
Benin has positioned itself as a heritage tourism destination for visitors of African descent, particularly from the United States, centered on the history of the trans-Atlantic slave trade. More than a million Africans were held and transported to the Americas through the port at Ouidah. A national project called La Marina is being developed at the site, combining preservation of slavery monuments with a five-star hotel, pools, spas, and restaurants, with completion expected this year.
In Togo's capital Lomé, a city of approximately 2.5 million people on a 35-mile coastal strip, President Faure Gnassingbé has held power since 2005. The city grew from a population of roughly 80,000 at independence in 1960. Lomé has long served as a regional economic hub linking larger neighboring economies.
The Nana Benz — working-class women who built wealth importing Dutch wax fabrics beginning in the 1950s and became cultural symbols of enterprise — are frequently cited as an example of corridor prosperity that many now describe as out of reach. Experts attribute their decline to market saturation, the 1994 devaluation of the regional currency, IMF-backed trade liberalization that reduced protections for local industries, and competition from cheaper Chinese imports.
Ghana's capital Accra, a commercial city of nearly 3 million people roughly 120 miles west of Lomé, is experiencing demographic shifts driven by climate pressures, rural poverty, and the concentration of economic activity in southern urban centers, according to researchers. Migration from inland and Sahel communities toward coastal cities has increased the population of informal workers and traders.
Social anthropologist Alice Hertzog of the University of Zurich, who has researched migration and urbanization in the corridor, said urbanization in the region has occurred without commensurate job creation, leaving many residents to pursue livelihoods through mobility and informal trade across the corridor's boom-and-bust cycles.
- ECOWAS has not been quoted directly on the status, funding, or timeline of the $15 billion superhighway project.
- No independent economic data is provided to quantify the decline in cross-border trade along the corridor.
- The precise number of people displaced by demolitions in Cotonou and along the Ouidah route is not established.
- The legal basis or authorization for the beachfront demolitions in Benin is not established beyond community members' characterization of them as illegal.
- The newly elected Beninese President Romuald Wadagni's specific policy positions beyond a vow to continue his predecessor's trajectory are not detailed.
- No representatives of the checkpoint operators — immigration, police, or military — are quoted or given an opportunity to respond to allegations of extortion.
