I-205 Multi-Use Path Professional Review and Guide
"The I-205 Multi-Use Path spans 18.5 miles through five cities and 15 neighborhoods along I-205 and the TriMet MAX Green Line light rail service. In addition, it joins with the 21.5-mile Springwater Corridor, making it an important commuting connection in the greater Portland area.
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, and, in 2011, 5,000 new trees and shrubs—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."
