Bridge River, River in British Columbia, Canada

Bridge River is a 142-kilometre river in the Pacific Ranges of the Coast Mountains, flowing from the Bridge Glacier to the Fraser River. Since the Bridge River Power Project was completed in 1961, most of its water is diverted through Mission Mountain to Seton Lake, leaving the lower canyon below Terzaghi Dam largely dry.

The river became an important route for prospectors during the gold rush of the 1860s who traversed the region. Trading routes followed its valley and brought early settlers to the remote area.

The river's Lillooet name is Xwisten, pronounced Hwist'n. Simon Fraser's 1808 party called it Riviere du Font, later rendered in English as Fountain River, and old maps show Shaw's River after one of Fraser's men. The Bridge River name comes from a pole bridge the St'at'imc built across the Fraser, replaced in 1858 by a settler tollbridge.

The best time to visit is from spring through fall when water levels and weather conditions are favorable. The area surrounding the river is remote, so sturdy footwear and supplies are important to bring along.

The valley surrounding the river is home to rare plants adapted to the cold mountain climate. This vegetation is unusual in the region and draws botanists and nature enthusiasts.
