West African highway linking Nigeria to Ivory Coast could help reinvigorate Ecowas

The shock of the three countries’ withdrawal may boost those pushing for tougher governance and democracy rules.

Meanwhile, the ambitious coastal transport corridor project, conceived to support economic development, will also serve a political purpose – demonstrating the remaining member countries’ capacity to work together and accelerating the trade growth and investment attraction of coastal urban West Africa, already the most prosperous part of this vast region.

And just as the EU’s wealth and dynamism proved a powerful attraction for former communist states, perhaps rising prosperity across Ecowas will eventually entice the now disenchanted further north states into rejoining the bloc.

Construction of the proposed four-to-six lane motorway is forecast to create 70,000 jobs, with completion ambitiously targeted for 2030.

And the plan is to acquire a sufficiently broad strip of land along the route to later accommodate a new railway line, linking the big port cities along the Gulf of Guinea. Existing rail routes extend inland, but there is no rail line along the coast.

The road will connect many of West Africa’s largest cities – Abidjan, with 8.3 million people, Accra (4 million), Lomé (2 million), Cotonou (2.6 million) and Lagos, estimated at close to 20 million or perhaps even more.

Several of the cities are key gateway ports for the flow of trade in and out of the region.

Already the bureaucratic hassles and risks of petty corruption that have so often complicated life for drivers passing from one country to the next are beginning to wane.

At many border crossings, modern one-stop frontier posts, where officials from both countries work side by side to check passports and transit documents, have replaced the assorted huts where drivers and passengers queued at a succession of counters while one set of border police and customs officers after another laboriously worked their way through the formalities.

And now the proposed highway and rail line promise to further speed the flow of trade and travel between the coastal economies, boosting competitiveness and integration and transforming the region’s attraction for investors – just as the EU transformed trade and development across the European continent.

And that process of economic and administrative integration of course had enormous political consequences.

It acted as a powerful incentive for countries still outside the bloc to improve economic governance, strengthen democracy and tackle corruption, in the hope of qualifying for membership.

Perhaps Ecowas can emulate this precedent, and lure the dissident states into re-joining, particularly if flagship projects such as the transport corridor give a real fillip to growth.

For not only do Mali, Niger and Burkina face severe development and security challenges, but they are also all landlocked, and heavily dependent on their coastal neighbours, through transport, trade and labour migration.
