The ever busy road was blocked around 8:30am local time today, Monday.
Thousands of road users heading to different parts of the country are now stranded to the incident.
But the protesting drivers have remained defiant despite calls for the road to be reopened.
Only last week, commuters plying the road ?suffered a similar experience for about 15 hours.
This followed a face-off between the drivers and security personnel on the state governor’s entourage.
