It runs from Marabella to the South Trunk Road interchange at Cipero Street.
Construction on the road began in the 1940s to allow traffic to pass along the eastern boundaries of the city as opposed to the centre.
The road is suspected to have opened in the mid-1950s and has since been expanded and upgraded to a four-lane dual carriageway as we know it today.
Excluding the Marabella to Tarouba segment, which is two lanes, the entire route is a four-lane dual carriageway.
It is not grade separated and suffers from frequent congestion during rush hour, especially at the Tarouba and Mon Repos roundabouts.
