The R620 begins at an intersection with the R102 in Oslo Beach, south of Port Shepstone CBD. It begins by heading south as Marine Drive, into Oslo Beach and crosses the Zotsha Creek to enter Shelly Beach. It passes through Shelly Beach and crosses the Mhlanga River to enter St Michael’s-on-Sea and Uvongo. After passing through Uvongo, it reaches the intersection with Seaslopes Avenue, after which it enters Manaba Beach.[1]
It then proceeds to descend into Margate, where it separates from Marine Drive (which heads into Margate Central) and bypasses Margate Central as National Road, before rejoining Marine Drive in the south of Margate. It then proceeds through Ramsgate and crosses under the R61, where it rounds and crosses the Mbizane River before ending shortly after at a junction with the R61 in Southbroom.[1]
