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.
