Kenya Airports Authority (KAA) will soon begin a technical study to build a second runway at Jomo Kenyatta International Airport (JKIA).
The study, to be commissioned in the next two months, will include planning, preliminary design, costing and documentation for construction, according to Daily Nation.
The second runway will be part of the northern corridor infrastructure programme, which is estimated to cost KES32bn ($400m) and will be completed by 2015.
The runway project will begin after the KES26bn ($304m) is extended on phase two, three and four of the JKIA upgrading project.
The second runway will be a fall-back option when the existing runway, which registers nearly 80% utilisation during peak periods, is closed for maintenance.
KAA's corporate affairs manager Dominic Ngigi said the second runway will be planned within the next three to five years.
KAA will contribute KES9.6bn ($120m) from its own resources for the project.
