Blaise Diagne International (AIBD) will have initial capacity for three million passengers per year, rising to 10 million per year, making it one of the highest-capacity airports in Africa.
Blaise Diagne will take over services from Senegal's current flagship airport Léopold Sédar Senghor International in capital city Dakar, which will cease operations.
The $575 million megaproject is envisioned as the centerpiece of an ambitious new development program.
The new airport is based in rural Diass, around 40 kilometers east of Dakar.
The remote location offers more space for the project than the crowded capital, where the existing airport has been affected by heavy traffic congestion.
Blaise Diagne occupies a 4,500-hectare site compared with 800 hectares at Léopold Sédar Senghor. The new airport also boasts a larger terminal and runways that can accommodate more passengers and flights.
"The AIBD airport is definitely a state-of-the-art infrastructure project," says El Hadji Beye, a civil engineer specializing in West Africa. "The new facility's increased size can accommodate larger planes like the Airbus A380 and will handle much more air traffic than before."
The AIBD development team expects
Blaise Diagne to become a primary hub of the West Africa region and a "preferred stopover point for air traffic in Africa, Europe and the Americas."
The new airport is also intended to diversify an economy that has become reliant on the capital.
Dakar accounts for half of Senegal's urban population and around 55% of GDP, according to the World Bank,
and it is growing fast.
"The idea is to see if we could drag economic activities out of Dakar," says AIBD Deputy Director General El Hadji Ibrahima Mané, "New infrastructure is essential to this (ambition)."
Blaise Diagne is to be the centerpiece of an "airport city," says Mane. French firm Lagardère Travel Retail has been contracted
to operate 1,000 square meters of duty-free stores on the site, and the AIBD team are planning for commercial development of the surrounding area including hotels, malls, restaurants and business facilities.
New transport links are being established between Diass and the capital, including the Dakar regional express train
and the Dakar toll road
. The airport is also expected to improve access and boost visitor numbers to other parts of the country such as tourist destinations on the southern coast.
Local communities should also benefit from new employment opportunities.
"The project will engage 540 full-time employees during the operational phase, including more than 200 women," says Rokhaya Diop Diallo of the Africa Development Bank's Senegal office, which is supporting the project.
"In addition to direct employment at the airport, the project will require other services in engineering, security, spare parts, information technology and services, catering and cleaning, that will boost the local economy."
