Major cities, small towns, and natural tourist attractions are closely connected by roads, making it particularly easy to travel by car.

The most important transportation route in Oregon is I-5. This road runs from Washington State to California, traversing Oregon from north to south. It passes through Portland, Salem, Eugene, and Medford in succession. It serves as a central route for logistics and passenger movement, and in Portland, it connects directly to Washington State across the Columbia River.

I-84 starts in Portland and heads east through The Dalles and Pendleton, continuing to Idaho. This road features a particularly beautiful stretch that runs along the Columbia River. The canyon scenery, with cliffs and rivers, is considered one of the most famous driving routes in Oregon. At the same time, it is a key route leading to eastern Oregon and the Rocky Mountain region.

I-205 is a secondary route that runs along the eastern outskirts of Portland. It helps to disperse urban traffic and is very useful for accessing suburban areas and the airport. I-405 is a short highway that connects the downtown area of Portland. It is responsible for downtown accessibility and connections to I-5.

Among U.S. highways, US-101 is the most popular. It is a coastal road that connects Astoria, Newport, and Coos Bay along the Pacific coast.

US-20 starts in Newport and crosses central Oregon to Idaho, showcasing the typical Oregon landscape with rural scenery and small towns. US-26 connects Portland to the eastern desert region, passing by Mount Hood. It is the most important route heading towards Mount Hood.

Among Oregon's highways, OR-18 quickly connects the Willamette Valley to the Pacific coast. It passes through wine-producing areas and is popular with tourists. OR-58 is a road that leads from Eugene to the eastern highlands, serving as a major route to ski resorts and various recreational areas.

The greatest advantage of Oregon's road network is that the journey itself becomes part of the travel experience. The Columbia River Gorge on I-84 and the Pacific coast on US-101 are among the most scenic driving stretches in the United States. In winter, there are sections with snow and ice, especially in mountainous and eastern areas, where tire chains may be required. The guidance system and snow removal management for this are relatively thorough.

Additionally, Oregon has a well-established network of electric vehicle charging stations, making it convenient for eco-friendly vehicle drivers. The freeway system in Oregon connects nature, urban areas, and industrial regions, serving as a significant advantage for both travel and relocation. By effectively utilizing this road network, you can experience the true charm of Oregon in the most comfortable way.
