Much of the road's route was initially signed as the Southern Main Road, but the entire route was eventually widened to a four-lane dual carriageway and eventually extended south to meet the extended Sir Solomon Hochoy Highway.
This section of roadway has been raised to prevent flooding, but is currently a two-lane road as the outer carriageway remains incomplete.
[1] The road bridges over the Godineau River at Mosquito Creek, past the Shore of Peace cremation site.
For its entire route excluding parts Mosquito Creek, the road is a four-lane dual carriageway.
Between Mosquito Creek roundabout and the Sir Solomon Hochoy Highway, the road is grade-separated.
