Cornelius Pass Road is an arterial road over Cornelius Pass in the Tualatin Mountains west of Portland, Oregon, United States. Running north–south, the road stretches between U.S. Route 30 on the north and Oregon Route 8 on the south. The road passes through Washington and Multnomah counties, crossing the Tualatin Mountains at Cornelius Pass at the 577-foot (176 m) elevation.TriMet's MAX Light Rail line (Blue Line or Westside MAX) travels over the road on a bridge.
The road was built by Thomas R. Cornelius in the 1800s. The interchange with the Sunset Highway (U.S. 26) was rebuilt and widened in 1989, and the road widened to five lanes from the freeway to Cornell Road the following year. In 1996, the road was extended southward when 216th and 219th avenues were renamed and became the southern section of the road, terminating at Tualatin Valley Highway. At that time the intersection with Baseline Road was re-aligned. The intersection with U.S. 26 was revised in 2005 with new on- and off-ramps extending from Cornelius Pass to the east, where a railroad overpass had previously been located. In 2008, the entire Multnomah County section was changed to a no-passing zone on the winding road over the Tualatin Mountains.
A one-mile section from Lois to Wilkins streets closed for eight months in 2010 in order to widen the road in that area to five lanes as well as add bike lanes and sidewalks. The $12 million project included a new 182-foot (55 m) bridge over Beaverton Creek. The county hoped to widen the remaining portion of the road to five lanes between Walbridge/Aloclek and Wilkins. Announced in 2011, the expected cost was $10.1 million and would include a new bridge over Rock Creek. Construction closed the section for six months, with the new bridge opening on December 31, 2012, while the remaining widening is expected to continue until the middle of 2013.
