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.
The I-205 Multi-Use Trail runs between I-205 and Lewis and SE 23rd St. (Vancouver, WA) to SE 82nd Dr. (Clackamas) and SE Highway 212 and SE McKinley Avenue (Clackamas) to 82 Drive (Gladstone).
