The Hood River–White Salmon Interstate Bridge, or just the Hood River Bridge, is a truss bridge with a vertical lift that spans the Columbia River between Hood River, Oregon, and White Salmon, Washington. It connects Interstate 84/U.S. Route 30 on the Oregon side with Washington State Route 14.{{Cite news |last=Libby |first=Amy |date=2023-12-27 |title=Hood River Bridge closed to all traffic in Gorge; no estimated time for reopening |url=https://www.columbian.com/news/2023/dec/29/hood-river-bridge-closed-to-all-traffic-in-gorge-no-estimated-time-for-reopening/ |access-date=2023-12-29 |work=The Columbian |language=en-US}}

The bridge is the second oldest existing road bridge across the Columbia River between Washington and Oregon. It was built by the Oregon-Washington Bridge Company and opened on December 9, 1924. The original name was the Waucoma Interstate Bridge.

Construction of the Bonneville Dam {{convert|23|mi|km}} downstream forced the bridge to be altered in 1938 to accommodate the resulting elevated river levels. On December 12, 1950, the Port of Hood River purchased the bridge from the Oregon-Washington Bridge Co. for $800,000.

The bridge is operated as a toll bridge by the Port of Hood River.{{Cite web |title=Hood River Bridge |url=https://portofhoodriver.com/bridge/ |access-date=May 27, 2022 |website=Port of Hood River}}{{Cite web |title=Toll Rates |url=https://portofhoodriver.com/bridge/toll-rates/ |access-date=May 27, 2022 |website=Port of Hood River}} Bicycles and pedestrians are prohibited from crossing the bridge due to its lack of sidewalks and narrow width.{{cite web |date=October 12, 2012 |title=Hood River–White Salmon Interstate Bridge: Structural Considerations for Pedestrian Crossing on the Existing Bridge |page=2 |url=https://portofhoodriver.com/wp-content/uploads/2020/01/Bridge-Pedestrian-Crossing-Study.pdf |publisher=Port of Hood River |accessdate=February 2, 2023}}

Twenty piers are used to support the total length of 4,418 ft (1347 m). When closed the vertical waterway clearance is 67 ft (20m). This increases to 148 ft (45 m) when the bridge is open at a river level of 75',{{Cite web |title=USGS Current Conditions for USGS 14113290 COLUMBIA RIVER AT HOOD RIVER, OR |url=http://waterdata.usgs.gov/nwis/uv?site_no=14113290 |website=United States Geological Survey}} which typically happens once or twice a month. The horizontal waterway clearance of the lift span is 246 ft (75 m).

The bridge has weight restrictions: 24 tons for legal truck types 3 and SU5, 32 tons for types 3S2 and 3-3, 22 tons for type SU4, and 25 tons for types SU6 and SU7 (descriptions of these truck types can be found [https://portofhoodriver.com/wp-content/uploads/2021/02/Attachment.Oregon_Load_Posting.pdf here]).{{Cite news |date=February 5, 2021 |title=New Weight Limit Imposed on Hood River-White Salmon Interstate Bridge |url=https://portofhoodriver.com/new-weight-limit-imposed-on-hood-river-white-salmon-interstate-bridge/ |publisher=Port of Hood River |access-date=May 27, 2022}}
