Better newer roads key to development
WASHINGTON, USA-- An adequate and reliable road network will be key to Africa’s economic development according to a new study compiled by a group of multilateral agencies.
Good-quality road connections can greatly expand access to jobs, markets, schools, and hospitals. For rural communities, in particular, a road is often an essential lifeline that links isolated villages to economic opportunities and services.

The study has been developed with financial support from the UK Department for International Development (DFID), the Nordic Development Fund (NDF), the Kredit Anstalt für Entwicklung (KFW), the Agence française de développement (AFD); the BankNetherlands Partnership Program (BNPP); and the Trust Fund for Environmentally and Socially Sustainable Development (TFESSD).
ESSENTIALS: The study sayd good quality road connections can greatly expand access to jobs, markets, schools and hospitals, while for rural communities a road is often an essential lifeline .
