Motorists using the busy stretch around the Tetteh Quarshie Interchange should prepare for significant traffic adjustments beginning Monday, March 9, 2026 as authorities begin a critical phase of construction works linked to the expansion of the Accra–Tema Motorway project.
In a public announcement issued by the Public Affairs Division, through the official Facebook page of the Ghana Highway Authority (GHA), it encouraged the public to seek further clarification through its official WhatsApp contact line.
Under the new arrangement, lanes on the northbound carriageway of the N4 (Accra to Madina direction) will be temporarily closed to allow construction activities to proceed safely.
To ease traffic flow during the period, the southbound carriageway (Madina to Accra) – which normally carries four lanes – will be reconfigured into two lanes in each direction, allowing vehicles to travel both ways on the same stretch.
According to the GHA, the temporary measure is expected to remain in place for about four months while engineers complete the structural works required for the bridge expansion.
Drivers are, therefore, being urged to exercise caution, obey traffic signs and directions from traffic management officials, and plan their journeys accordingly to minimise delays.
The road works form part of broader efforts by government to expand and modernise key sections of the motorway corridor linking Accra to surrounding urban communities, including Madina.
