The Kenya National Highways Authority (KENHA) awarded the tender worth Ksh27.29 billion to China Communications Construction Company (CCCC) and Territorial Works Ltd.
The murram will cover a total of 453 kilometres. From Lamu to Garissa through Ijara will cover 257km, Hindi-Bodhei-Basuba-Kiunga section will cover 113km while the Ijara-Sangailu-Hulugho will be 83km.
