The Umatilla Bridge is the collective name for a pair of bridges in the northwest United States, carrying Interstate 82/U.S. Route 395 (I-82/US 395) across the Columbia River at the Washington–Oregon border. The older bridge opened in July 1955 and is a steel through truss cantilever bridge and carries southbound (east on I-82) traffic. Northbound traffic (west on I-82) and pedestrians travel on the newer concrete arch bridge, opened in 1988.
