The Barlow Road begins at Wascopam Mission and heads south to Tygh Valley (some consider Tygh Valley the origin), then turns west and roughly parallels the White River on the north and then west, crosses the south shoulder of Mount Hood at Barlow Pass, follows Camp Creek and the Sandy River for some way, and finally leads to Oregon City. The road was rendered largely irrelevant in the early 1900s by the construction of the Mount Hood Highway. It still exists as a dirt road in some places, while many other parts have been paved over by newer streets and highways.
