Ghana’s ambitious “Big Push” infrastructure program, a multi-decade effort to upgrade national road networks, faces a critical challenge: preventing uncontrolled community development along newly constructed and rehabilitated highways. This initiative, which includes major projects like the Accra-Kumasi Expressway and the Eastern Corridor Road, aims to boost mobility and trade but risks becoming a victim of its own success if roadside settlements and commercial activities are not strictly managed.
A Foundation for Progress, A Risk of Congestion
The “Big Push” represents Ghana’s most significant investment in road infrastructure in decades. Across the nation, vital corridors are undergoing transformation through rehabilitation, expansion, and new construction. These projects are designed to foster national integration and facilitate the movement of goods and people, underpinning economic growth.
However, a recurring pitfall in developing nations is the unchecked encroachment of settlements onto these high-speed arteries. What begins with a few roadside vendors or a fuel station can rapidly evolve into a dense network of homes, shops, schools, and places of worship, effectively turning a highway into a local street.
The Highway Becomes a Town Road
This transformation fundamentally compromises the highway’s intended purpose. High-speed, intercity travel becomes mired in constant congestion as vehicles entering and exiting numerous local access points disrupt the flow. Journeys that should take hours can stretch significantly longer, negating the efficiency gains the infrastructure was meant to provide.
The human cost is even more profound. The integration of pedestrian activity onto high-speed roads creates a dangerous environment. Residents, traders, and children are forced to cross busy traffic daily, increasing the risk of accidents. In many instances, roads physically divide communities, making daily life a hazardous undertaking.
Preventing a Cycle of Congestion and Tragedy
Experts highlight that many fatal road accidents in Africa are not solely due to driver error or speeding, but are exacerbated by poor spatial planning around major roads. A highway is engineered for efficient movement, not as a multi-purpose urban thoroughfare that serves as a market, bus terminal, and residential access route simultaneously.
Globally, protected highway corridors are standard practice. Controlled access through interchanges, service roads, and designated exits ensures that highways remain dedicated to transit, with towns and communities accessed via planned entry points. Ghana’s authorities are urged to adopt this long-term perspective to safeguard the “Big Push” investments.
Enforcement and Collaboration are Key
The Ministry of Roads and Highways, District Assemblies, physical planning authorities, and traditional leaders must collaborate to implement and enforce strict development controls. Relaxing setback regulations or tolerating unauthorized roadside developments for short-term political or economic convenience could lead to irreversible problems.
The gradual nature of settlement creep makes it insidious. One structure appears, followed by another, until the highway is irrevocably altered. Once communities are established, relocating them becomes politically fraught, socially disruptive, and prohibitively expensive.
Measuring True Success
The ultimate success of the “Big Push” program will be measured not just by the kilometers of road built, but by the long-term viability and efficiency of these corridors. Failing to protect them from encroachment risks creating more congestion, increasing pedestrian fatalities, fostering disorder, and necessitating costly future reconstructive efforts.
The decisions made today regarding corridor protection and settlement control will determine whether Ghana’s modern highways serve as efficient national arteries for decades to come or become monuments to preventable congestion and tragic accidents. The focus must shift from mere construction to the enduring preservation of the infrastructure’s intended function.
