The Ghana Highway Authority, on behalf of the Ministry of Roads and Highways (Ghana), has announced a temporary traffic management plan to support ongoing construction works on the Accra–Tema Motorway and its extensions.
In a press statement, the Authority explained that the new arrangement will allow engineers to carry out T-beam launching works as part of the expansion of the Tetteh Quarshie Interchange bridge on the N1 highway.
The project is a major infrastructure upgrade designed to reduce congestion and improve traffic flow in the area.
Under the temporary traffic plan, lanes on the N4 northbound carriageway from Accra to Madina, Greater Accra, Ghana, will be closed to make room for the construction work.
Meanwhile, the southbound carriageway, which normally has four lanes for vehicles travelling from Madina to Accra, will be rearranged to carry traffic in both directions.
Two lanes will be used for vehicles heading to Accra and two lanes for vehicles heading to Madina, helping to keep traffic moving during the construction period.
The temporary arrangement will take effect on Monday, 9 March 2026, and is expected to last for approximately four months.
The lane reduction, according to the Authority, is necessary to create a safe working environment for construction personnel while ensuring the continued safety of motorists using the route.
The Ghana Highway Authority has therefore urged all motorists to exercise caution, adhere strictly to traffic signs, and cooperate with traffic management officials throughout the duration of the works.
