[edit] History

There are two bridges along the route of SR 173. They each cross the same river, the Columbia River. The bridge at Brewster was built in the 1920s, but the bridge at Bridgeport was built at about the same time as the Chief Joseph Dam, around 1950, which was built nearby. The Bridgeport bridge caught fire sometime in the 1960s and was replaced with the current bridge.

Before 1964, SR 173 was the Brewster-Bridgeport branch of PSH 10.^[2]
