Traffic Changes Announced on N1 as Ghana Highway Authority Begins Bridge Expansion at Tetteh Quarshie Interchange
The Ghana Highway Authority, on behalf of the Ministry of Roads and Highways, has announced a temporary traffic management arrangement as part of ongoing construction works on the Accra–Tema Motorway Extension Project. The measure will allow contractors to carry out T-beam launching works for the expansion of the Tetteh Quarshie Interchange bridge along the N1.
In a post made on X on Monday, March 9, 2026, it revealed that as part of the arrangement, lanes on the N4 northbound carriageway from Accra toward Madina will be temporarily closed. Meanwhile, the southbound carriageway from Madina to Accra, which currently has four lanes, will be converted to carry traffic in both directions.
Under the new setup, the southbound side will be divided into two lanes for vehicles traveling from Accra to Madina and two lanes for vehicles traveling from Madina to Accra. The temporary traffic arrangement will take effect from Monday, March 9, 2026, and is expected to remain in place for about four months.
According to the Ghana Highway Authority, the lane reduction is necessary to create a safe working environment for construction personnel and to ensure the safety of road users. Motorists are therefore advised to exercise caution, follow traffic signs, and cooperate with traffic management officials throughout the construction period.
