Spreetshoogte Pass
Spreetshoogte Pass (, literally ) is a mountain pass in central Namibia, connecting the Namib Desert with the Khomas Highland by traversing the Great Escarpment, a geological feature of much of the southern part of the African continent. With gradients between 1:4.5 and 1:6 it is the steepest pass in Namibia, as well as the one straddling the biggest elevation difference, descending almost within of road. The top of the pass features a rest place from which there are views into the adjacent Namib. The pass was erected during World War II by farmer Nicolaas Spreeth, after whom it is  named. Spreeth owned the farm "Ubib" just at the foot of the escarpment. Whenever goods were delivered to his farm they would be dropped at a bus stop at farm "Namibgrens" () on top of the mountain. To gather them the choice was to either travel via Remhoogte Pass approximately southwards, or to trek uphill along existing Zebra paths. Spreeth decided to do the latter, fortifying the path with quartzite rocks whenever he undertook the journey. Soon the bright white rocks formed a line that could be spotted from a distance. Spreeth even catered for motor vehicles (not very strong at  that time), placing long, flat patches of road ahead of every steep ascent. He built the pass literally with his own hands. To flatten obstacles he used dynamite. The pass today is part of the district road D1275 from Rehoboth to Solitaire, passable only for vehicles without trailers. Trucks and caravans are forbidden to use it. Even trucks and graders of Namibia's Roads Authority only drive uphill when maintaining this stretch of road, and return via the Remhoogte Pass nearby, in order to keep the danger of failing brakes to a minimum.
