Directions to Jolly Roger.
A shortcut that is very worth considering is the Moamba - Xinavane road.
If it has been Raining then the NORTH road is the one to take. It is fairly rocky (small rocks) in places, but, is negotiable with most vehicles (except smallish sedans).
The SOUTH road is smoother than the North but is difficult and slippery in patches during times of rain.
Both roads (going North) join just after Magude. The NORTH road crosses a long Rail bridge where you may have to wait a while as it is a Rail / Single carraige road. The SOUTH road joins the NORTH road just after (or North) of this bridge.
From here you continue to and through Xinavane to the "T" junction on the EN1, here you turn Left and continue on to Xia Xai and Northwards to Us.
We are +-179km from Xai Xai (or 2 Hours).
Many, many thanks to all the guys and girls on DriveMoz for this info.
