The town had its start as one of the main centres of the Fraser Canyon Gold Rush of 1858–59, during which it was reckoned to be "the largest town west of Chicago and north of San Francisco", a title also held by certain other towns in British Columbia in rapid succession (Yale first, Barkerville after). Just after this gold rush, the town's layout as it is today was surveyed by the Royal Engineers and its Main Street tied into the original Cariboo Wagon Road or Old Cariboo Road to Fort Alexandria, a huge project undertaken as a toll road by Gustavus Blin Wright, one of the many entrepreneurial personalities of the early colony. Much of its tortuous canyon-brink road grade for twenty or thirty kilometres from "Mile 0" remained in use until the 1970s.
