Canyon Road (formerly known as Great Plank Road[1]) is a 6.5 mi (10.5 km) major road and partial state highway, which serves as a connector between Beaverton and Portland, Oregon, United States. It was the first major road constructed between the Tualatin Valley and Portland, and has contributed significantly to Portland becoming the area's major deep water port, and subsequent early growth of the city.[2] The total modern length is 6.5 miles (10.5 km),[3] and 2.7 miles (4.3 km) of the route is coterminous with U.S. Route 26.[4] In addition, the segment of the road signed as Oregon Route 8 under the name Canyon Road spans for 3.8 miles (6.1 km).[5] There is an additional, small portion of a driveway in the Oregon Zoo parking lot that is also named Canyon Road; this is a continuation of a local suburban street named Canyon Court.[6]
