Sunrise Expressway

On the busy, eastside industrial part of the Portland metro area, commercial and residential traffic to and from I-205 led to congestion, limited business access, and cramped multimodal options.

OBEC led a large, multidiscipline team through an accelerated, iterative design process to create the first new highway in the Portland metro area in almost 30 years. The project was aimed at reducing business and access impacts, minimizing right-of-way acquisition, avoiding industrial sites with significant hazmat issues, and satisfying the concerns of ODOT and area stakeholders. The result created major interchange/intersection improvements that streamlined freeway access and significantly reduced back-ups on neighboring arterials.

Now that the roadway is open, ODOT estimates that the Sunrise Expressway reduces congestion by more than 1 million hours each year while also increasing safety and creating opportunities for new economic development.

  • The project included more than 12,000 feet of new roadway, 9,500 feet of multiuse paths, three new roadway bridges, two new pedestrian bridges, 18 roadway/trail retaining walls, and major interchange/intersection improvements.
  • Stormwater management facilities serve an area with flat topography that covers three separate watersheds.
  • Structures and foundations were designed in a seismically active area with potentially liquefiable soils.
  • Low-risk contaminated soils from the Superfund site in the project area were effectively encapsulated under the new roadway.
  • Now that the roadway is open, ODOT estimates that the Sunrise Expressway will reduce congestion by more than 1 million hours each year while also improving safety and creating opportunities for new economic development.
