The Eldoret International Airport's runway will be expanded to four kilometres, to accommodate bigger planes.
Roads Cabinet secretary Kipchumba Murkomen said 15.61 hectares (38.57 acres) will be required for the extension.
In his submissions to National Assembly's Committee on Transport and Infrastructure, the CS said the airport has one runway, which is 3.5km long and 45m wide.
"It currently handles Ethiopian Airlines and Emirates, both operating wide-bodied cargo aircraft (B777) from the Middle East," he said.
"In order to optimise take-off operations at maximum take-off weight by the aircraft, KAA intends to undertake and expansion."
The CS was responding to a question asked by Baringo Central MP Joshua Kandie.
Murkomen had issued instructions on the rehabilitation of airfield ground lighting.
He further directed on the provision of taxiway and runway shoulders for safety as well as expansion of the apron area to accommodate more aircraft.
The CS also gave the order for acquisition of an additional 19.74 hectares (48.77 acres) of land for the development of hangar facilities.
Eldoret International Airport, which was opened 24 years ago remains under-utilised in terms of exports and contribution to the county and regional economy.
The facility was expected to boost agriculture in the region through exports as well as promote tourism.
Flower farms and other fresh produce in the North Rift region of Uasin Gishu and Trans Nzoia counties transport their produce by road to Jomo Kenyatta International Airport for export.
There have also been mounting calls from different quarters to extend the runway by 500metres from 3.5 kilometres to four kilometres to accommodate larger freight flights
