For many years in Spokane’s early history as a city, the Howard Street bridges were the only way to get across the Spokane River, not counting wading, swimming or taking a ferry. Traffic first crossed the three bridges in 1881, and for much of the following century vehicles traveled from the river’s north bank and over the islands before finally crossing under the tall trestles of the elevated Union Pacific rail lines and into downtown Spokane. Factories surrounded the traffic, milling lumber, wheat and power in what is now Riverfront Park.
