The Government if Kenya through the Kenya National Highways Authority (KeNHA) is set to upgrade the Mombasa to Mariakani section of the A109 road. The road will be a six lane dual carriageway running from Kwale County to Mombasa, Mombasa to Mariakani on the Mombasa-Nairobi Highway and Mombasa-Malindi Highway. The project will see the expansion of a 41.7km stretch which forms part of the 500km Mombasa-Nairobi highway.


The upgrading project will include erection of interchanges, flyovers, bus bays, service roads, truck parking, pedestrian foot bridges, street lighting and associated soft components along the road.

AECOM RoA (PTY) Ltd in association with Cape Consult and Aquaclean Services Ltd carried out the feasibility study, preliminary and detailed design and Environmental Impact Assessment. The project is part of mitigations being implemented to ease traffic flow from the port of Mombasa to landlocked states in the region. An estimated 4,000 trucks use the road daily, causing massive traffic in Mombasa and delaying shipment of goods to Nairobi and other destinations in the East African region.

The Authority estimates that the project will cost KES22bn with construction set to begin mid 2016 and completed in three years time. African Development Bank (AfDB) in partnership with the National Treasury has signed a concessionary loan to finance the project with KES10bn. The loan will be used to build 11km road from Mombasa to Jomvu section. KeNHA is also negotiating with German Development Bank (KfW) to fund the remaining section from Jomvu to Mariakani at a cost of KES12bn.  In addition, the European Investment Bank and the Africa Infrastructure Trust Fund (AITF) will co-finance the road project.

The road project is a key import-export gateway and an important section of the Northern Corridor (NC), which links the port of Mombasa in Kenya with the land-linked Eastern and Central African countries of Uganda, Rwanda, Burundi and the Democratic Republic of Congo (DRC). The expansion of the road will also unlock the potential of agricultural activities thus strengthening the delivery of business and financial services for farmers and producers, enabling the flow of information, facilitating improved agro-processing infrastructures and improving linkages to markets.

AfDB has already used KES270bn in support of social and infrastructural development in Kenya to date; the road project is in line with the Government’s growth and poverty reduction efforts. Moreover, Trade Mark East Africa (TMEA) intends to raise KES47bn to fund projects like the relocation of the Kipevu Oil Terminal, deepening and straightening of berths 1 to 5 for general cargo, extending and straightening of berth 6-10.

The Authority with its partners will acquire 25 hectares (62 acres) of land leading to demolition of 820 structures including Public institutions, churches, residential houses and perimeter walls to pave way for construction. Therefore, the Authority has ensured that there is a well outlined compensation scheme for those who will be affected by setting up a committee to follow up.Finally, the rehabilitation and expansion of the Mombasa-Mariakani road is a flagship project under Kenya Vision 2030 that will ensure there is reduced emissions of carbon and associated gases as well as create job opportunities for the locals.
