​Five secrets of success of Sub-Saharan Africa’s first road PPP

Why is Senegal’s Dakar-Diamniadio toll road, which opened on time and on budget in August 2013, so successful? The road has dramatically improved urban mobility around Dakar, reducing commute times between the city and its suburbs from two hours to less than 30 minutes.  
 
Building on this positive experience, in 2014 the Government of Senegal awarded a further concession to extend the motorway to connect it to Dakar’s new Blaise Diagne International Airport. Excluding South Africa, this is the first greenfield road PPP in sub-Saharan Africa. What lessons can we draw? 
  1. Political commitment. The Government of Senegal set the project as a priority. The first driver on the road was the President – who paid the toll. But commitment alone isn’t enough; it needs to be turned into action by government agencies. An intra-agency coordinating committee was set up. The National Agency for the Promotion of Investments (APIX) oversaw the preparation of the concession. The Public Private Infrastructure Advisory Facility (PPIAF) supported APIX with technical assistance, including the design of a framework for the oversight of the project.
  2. Toll plaza along the road
    Consensus-building and stakeholder engagement.  Part of PPIAF’s US$250,000 grant to the Government of Senegal helped to pay for seminars with stakeholder groups to discuss structuring options for the road and socio-economic drivers of the willingness to pay. The final structure chosen involved a relatively low toll, with an upfront contribution by the government to the cost, with the concessionaire taking full construction, operating and traffic risk. The combination of careful outreach to stakeholders, a fairly low toll, significant time savings and a well-maintained road meant that the first toll road in the country was accepted by the population. In addition, the fact that there is a free alternative road helped the Government and other stakeholders point out that motorists could always choose to use the other route.
  3. Experienced concessionaire with strong commitment to Senegal. The concessionaire, the Eiffage Group is one of Europe’s leading construction and toll road operating companies, with a long history of involvement in, and commitment to, Senegal. Eiffage, through the special purpose company set up to construct and operate for 30 years the road, SENAC S.A., ensured that the road was constructed and is being operated to a high standard, on time and within budget.  

Lessons from China for Africa - my take

Thirty African officials visited China for 12 days in May on a pilot South-South knowledge exchange organized by the Chinese government with assistance from the World Bank.  My colleague, Phil Karp, has written about the program, including the study tour around China that he accompanied.  I met the officials in Beiji
