The tanker with registration number GT 2286-W, which was heading towards Kasoa from Accra, hit the pavement inbetween the road before it overturned, crossing the road.
As a result, vehicular movement from Accra to Kasoa had to be diverted to use the same route as those Kasoa coming to Accra.
The accident brought heavy traffic on the already congested highway as passengers trek on foot with vehicles stucking in the traffic.
Motorists moving into and out of Kasoa have been left stranded for several hours Wednesday morning following a possible gas leakage at Tetegu on the Kasoa road.
The road has been blocked to prevent casualties in case there was an explosion.
The situation has resulted in a heavy vehicular traffic on the Tetegu Kasoa as the police and the fire service try to offload the gas from tanker.
