Southwest Washington Regional Transportation Council (RTC) along with the Oregon and Washington Departments of Transportation (ODOT & WSDOT), the ports of Hood River and Klickitat, and the local cities and counties are working in partnership to find a long-term solution to the Columbia River crossing between Hood River in Oregon and White Salmon and Bingen in Washington.
Using the findings from the SR-35 Columbia River Crossing Feasibility Study and Draft Environmental Impact Statement (DEIS), completed in 2004, partner agencies will be completing a Bridge Type, Size, and Location Study (TSL) for a future new Columbia River Crossing between Bingen and White Salmon in Washington and Hood River in Oregon. During the TSL study process, engineers will collect and analyze data to develop several feasible bridge concepts. These concepts will then be evaluated against criteria developed from stakeholder input. The concept that best addresses stakeholder needs will be the recommended alternative.
In addition to the TSL Study, the current study effort will include artist renderings of the recommended alternative, an economic analysis of the Columbia River crossing, bridge cost estimates, and an outline for completion of the NEPA process.
The primary purpose of this project is to improve the movement of goods and people across the Columbia River between the Bingen/White Salmon, Washington and Hood River, Oregon communities.
The Columbia River Bridge, referred to locally as the Hood River Bridge, was built in 1924. The Bridge was vertically elevated and a lift span added in 1938 as the river water level was raised with the completion of the Bonneville Dam. The Port of Hood River purchased the bridge in 1950. The existing structure is 4,418 feet long and has two approximately 9.5-foot wide travel lanes with no pedestrian or bicycle facilities. It has open-grid steel decking, with a 246-foot lift span over the river navigation channel.
The Bridge spans the Columbia River, connecting the cities of White Salmon and Bingen in Washington to the city of Hood River in Oregon. This bridge is the second oldest Columbia River crossing and one of only three crossings in the Columbia River Gorge National Scenic Area. This major transportation route serves as an important link to local communities, the region, and interstate travel. The economic well being of this region is dependent on this Columbia River crossing.
The SR-35 Columbia River Crossing effort began in response to local business and resident concerns about the condition of the existing Hood River Bridge. The project began in 1999. The SR-35 Columbia River Crossing Feasibility Study concluded in January 2004 with the completion of a Draft Environmental Impact Statement (DEIS). The DEIS identified a new alignment just west of the existing Hood River Bridge as the preliminary preferred alternative. In addition, the feasibility study effort identified a number of short-term and medium-term bridge associated operational improvements. In the last few years, many of these improvements have already been implemented or are in the process of being implemented.
