Pokuase Interchange

Pokuase Interchange. The Pokuase Interchange is a major four-level stack interchange located in the Greater Accra Region of Ghana, serving as a critical node in the country's road transport network. It connects the N6 Highway, also known as the George Walker Bush Highway, with the vital Accra-Nsawam Road, facilitating movement to and from the capital and surrounding municipalities. Officially inaugurated on 9 July 2021 by President Nana Akufo-Addo, the interchange was constructed to alleviate severe traffic congestion that had long plagued the area, improving connectivity for communities like Awoshie, Kwabenya, and Ofankor.

Overview

The interchange is situated at a historically congested junction in the Ga West Municipal District, a fast-growing area on the northwestern outskirts of Accra. It forms a key part of the transport infrastructure designed to support economic activity in the Greater Accra Region and improve access to neighboring regions like the Eastern Region. The structure's primary function is to manage the high-volume traffic flows between the capital, the dormitory communities of the Ga West Municipal District, and major destinations such as the Kotoka International Airport and the Tema Port. Its completion marked a significant upgrade from the previous roundabout system, which was a notorious bottleneck affecting the Ghana Highway Authority's network efficiency.

Construction and design

Construction of the interchange was executed by the China Railway Construction Corporation Limited (CRCC) under the supervision of the Ghanaian Ministry of Roads and Highways. The project commenced in 2018 and was delivered using design-build procurement methods, with detailed engineering oversight from consultants like Associated Consultants Limited. The final design is a four-level stack interchange, a first of its kind in West Africa, featuring multiple flyovers, underpasses, and dedicated lanes to ensure uninterrupted traffic flow. Key materials and techniques aligned with international standards, and the project included the installation of modern street lighting, drainage systems, and pedestrian walkways. The construction phase faced challenges including utility relocations coordinated with the Ghana Water Company Limited and Electricity Company of Ghana, and adherence to strict timelines set by the Government of Ghana.

Impact and significance

The operational interchange has dramatically reduced travel times and vehicular congestion in the Ga West Municipal District, with estimated commute time savings of over an hour for many users during peak periods. This improvement has boosted economic productivity for businesses and residents in areas like Amasaman and Medie, while enhancing road safety and reducing vehicle operating costs. The project's significance extends to regional integration, providing a more efficient link for goods movement between Accra, Tema, and inland regions, supporting the broader goals of the African Development Bank for infrastructure-led growth. It stands as a flagship project of the Akufo-Addo administration's agenda to modernize national infrastructure.

Funding and project partners

The project was jointly financed by the Government of Ghana and the African Development Bank (AfDB), with the AfDB providing the majority of funding through a loan agreement. The Ministry of Finance and the Ministry of Roads and Highways were the lead implementing agencies on the Ghanaian side, ensuring fiduciary management and project oversight. Other key partners included the Ghana Highway Authority, responsible for technical standards and future maintenance, and international consulting firms that provided audit and advisory services. The collaborative funding model between the Government of Ghana and the African Development Bank is seen as a successful template for other major infrastructure projects within the Economic Community of West African States (ECOWAS) region.

Future developments

Future plans for the area include the potential development of complementary road networks and urban transit systems to maximize the interchange's capacity, as outlined in the Greater Accra Regional Coordinating Council's long-term transport strategy. There is also consideration for integrating the node with proposed bus rapid transit (BRT) lines and other mass transit initiatives to promote sustainable urban mobility. The success of the project has informed planning for other major interchanges in Ghana, such as those proposed for Tamale and Kumasi, under the purview of the Department of Urban Roads. Continued maintenance and potential smart traffic management system upgrades will be managed by the Ghana Highway Authority to ensure the interchange's long-term operational integrity.
