Interstate 84 in Oregon
section of Interstate Highway in Oregon, United States
Interstate 84 (I-84) in the U.S. state of Oregon is a major Interstate Highway that traverses the state from west to east. It is concurrent with U.S. Route 30 (US 30) for most of its length and runs 378 miles (608 km) from an interchange with I-5 in Portland to the Idaho state line near Ontario. The highway roughly follows the Columbia River and historic Oregon Trail in northeastern Oregon, and is designated as part of Columbia River Highway No. 2 and all of the Old Oregon Trail Highway No. 6; the entire length is also designated as the Vietnam Veterans Memorial Highway. I-84 intersects several of the state's main north–south roads, including US 97, US 197, I-82, and US 395.
The freeway serves as the main east–west route through Portland and Gresham and continues into the Columbia River Gorge National Scenic Area. It passes through the cities of Hood River and The Dalles within the gorge and also serves several state parks and natural monuments. Near Pendleton, it leaves the Columbia River and runs southeasterly across the Blue Mountains via La Grande and Baker City. I-84 crosses the Snake River at Ontario, continuing southeast towards Boise, Idaho.
