Traffic on the Accra-Tema Motorway has come to a standstill for about an hour, stretching from Flower Pot through Manet to 18 Junction.
Drivers and commuters are advised to use alternative routes.
The gridlock was caused by a gas tanker that had broken down on the opposite lane of the Tema Motorway near the Abattoir Bridge.
Fire Service and Police personnel are on-site, directing vehicles from the affected lane to use the right lane to ensure safety and prevent traffic congestion.
