Demerara River
Between 1966 and 1968, Soesdyke, located on the East Bank Demerara Road, was connected to Mackenzie by a modern two lane highway, called the Soesdyke-Linden Highway. This road was constructed as a section of a highway connecting Georgetown with Lethem. In 1968 a bridge was built across the Demerara River at Linden, and, in 1974, it was decided that the route to Lethem would cross the Demerara River at Linden and go south, along the watershed of the Demerara and Essequibo Rivers, through Mabura, to Kurupukari. From Kurupukari it would run parallel to the old cattle trail to Annai, and from Annai it would follow an already existing road to Lethem.
