The Hood River-White Salmon Interstate Bridge is a vital Columbia River crossing in the central Columbia Gorge bi-state region connecting Hood River, Oregon with the communities of White Salmon and Bingen in Washington State. The Bridge, nearly one mile long, is constructed of steel trusses on concrete pier supports with very narrow lanes (lanes are only 9 feet, 4.75 inches wide, with a 14 feet, 7 inches height restriction). The Bridge is limited to a Total Gross Weight Limit of 80,000 lbs, with each single axle limit of 20,000 lbs. The Bridge serves an average of 4 million users annually and is open every hour of every day, except during periods scheduled maintenance or emergency closures.
Often referred to simply as the Hood River Bridge, the aging structure is deficient by modern standards, but remains an essential transportation link between Oregon and Washington. The Bridge’s narrow lanes (9 feet, 4 inches) were characteristic of the 1924 era in which it was built, when horse-drawn carriages and Model-Ts crossed the Columbia on what was then a state-of-the-art structure.
The Hood River Interstate Bridge was essentially rebuilt in 1938 when the construction of the Bonneville Dam caused water levels to rise and made the addition of a lift span necessary. Nowadays, the lift span is raised several times a year and has become the iconic symbol of the historic Bridge purchased by the Port in 1950.
The Port takes its responsibility to assure the Bridge’s safety, operation and useful life into the foreseeable future extremely seriously, planning ahead and taking proactive action. The Port has invested over $22 million in capital improvements and maintenance in the past two decades, and expects sizable investments in the near and long term to keep the structure functional and operating safely into the future.
The Port of Hood River continues to work with state and federal agencies as a supportive partner in the effort and pursuit of bridge replacement. As years pass, the cost of bridge replacement, currently estimated at $250 million, continues to increase, meaning that funding for a new bridge will likely require pooled resources among local, regional and federal governments and agencies.
