I-205 Multi-Use Path Description


The I-205 Multi-Use Path spans 18.5 miles through five cities and 15 neighborhoods along Interstate 205 and the TriMet MAX Green Line light rail service. 

Although the trail parallels the busy I-205, most of the trail is separated a good distance and often protected by a wire fence, giving the trail a nice berth and separation from the roadway.

About the Route

Extending from the northern edge of the Columbia River in Vancouver, Washington, to Gladstone, Oregon, the trail and its amenities—including public art, topiary, wayfinding signage —attract thousands of cyclists and pedestrians each day. The state of Oregon first constructed the trail in the 1980s to improve biking and walking connections between neighborhoods, as well as between commercial and public destinations. The Oregon Department of Transportation reopened the entire route in 2011 after closing sections of it to implement a number of enhancements to make it more commuter friendly, such as the installation of new overhead lighting.

Bike routes and bike lanes connect several trail gaps. At I-205 and State Route 224/Milwaukee Expressway (also SE 82nd Drive), the trail transitions to bike lanes on SE 82nd Drive. Trail users can rejoin the main trail at SR 212/224. The path ends at the Gladstone interchange, which is just north of Oregon City and High Rocks State Park. The route continues along on-road sections to Oregon City via Agnes and Main Streets. Be aware that the tunnel does not have bike lanes.

The trail's northern endpoint is located at SE 23rd Street in Vancouver and runs south from there as it crosses the I-205 Bridge. It passes over Government Island, which—reachable only by boat—is known for its great blue heron colony and its state recreation area's primitive camping and beaches. The interior of the island is off-limits to the public.

Further south, the trail passes Marine Drive, the Sandy Boulevard trailhead, the Gateway Transit Center, and Powell Boulevard. Further south, the trail intersects with the Springwater Corridor and then SE Johnson Creek Boulevard, passing near Clackamas Town Center and Clackamas Promenade before ending in Gladstone. 

Less than 2 miles farther south, the trail stops at SE 82nd Drive and the I-205 Gladstone interchange.


At the Portland International Airport, the trail connects to the Marine Drive Trail.

In Southeast Portland, the trail intersects with the Springwater Corridor.

Use it or lose it!

This trail and it's construction is nothing short of amazing. Yet the pictures on the Rails to Trails website tell it all. It is not being used. Maybe it is because people are afraid of the homeless encampments that you see or because it is next to a freeway. But the homeless encampments would be much less of a problem if there were more people on bikes utilizing the trail. This trail I am sure cost millions yet just a few people use it. Get out there people!

I rode it last summer and it was an awful experience. Lots of trash and homeless and it smelled like feces in some parts.

Lots of garbage and campsites. Some sections are blocked with tents.
Neighborhood greenways are better.


great trail, but I keep getting lost southbound at hwy. 224. Some signs would be good. Even painted on the sidewalk. Anything! The trail just ends and -- bang-- you're face to face with highways going every which way.

Gladstone seems to be particularly unfriendly to bikes. Don't they understand that bike traffic brings money-spending traffic without congesting roads?


Inline Skater Review

I skated about 3.5 miles of this trail from Marine Drive south and really enjoyed it. Although there were seams in the trail, it was still very smooth. The scenery is varied, including a couple transit centers, through a neighborhood, and along some tracks. There are a few grades.
