Key Traffic Management Details

The Ghana Highway Authority (GHA) and the Ministry of Roads and Highways have narrowed lanes to facilitate critical construction work on the interchange bridge:

The Diversion: Vehicles traveling from Madina towards Independence Avenue have been diverted onto a three-lane road on the opposite side of the carriageway.

Lane Reduction: This arrangement effectively reduces the usual six-lane dual carriageway to a single carriageway, leading to significant bottlenecking.

Affected Areas: The congestion extends from the Tetteh Quarshie Interchange back toward the Accra–Tema Motorway and reaches toward Dzorwulu.

Construction Purpose: The diversions are required for central pier construction works as part of the broader $350 million Motorway Extension Project.

Public Safety and Advisory

Authorities are urging the public to exercise patience as these measures are vital for both worker and commuter safety:

Safety First: The GHA emphasized that the lane reduction is "necessary in the interest of Public Safety" to provide a secure working space for personnel.

Early Planning: Motorists are advised to set off earlier than usual or seek alternative routes through East Legon or the George Walker Bush Highway to avoid the heaviest delays.

Cooperation: Drivers are requested to follow all posted directional signs and cooperate with MTTD traffic officers stationed at the interchange.
