SR 522 - Paradise Lake Road Interchange

Project news

  • WSDOT selected a preliminary preferred alternative for interchange improvements. View the concept, along with those that were not chosen, on WSDOT's Flickr page.
  • The State Legislature provided $750,000 in the 2017-2019 biennium for traffic analysis, design/concept work, and early community engagement. That early work is now complete. Another $10 million becomes available from 2025-2029. There is no construction funding at this time.

Needs & benefits

Drivers regularly experience heavy congestion at the SR 522 Paradise Lake Road intersection. The congestion frequently spills over onto side streets and drivers try to find ways around the bottlenecks on the highway.

An improved interchange, capable of handling more cars more efficiently, will increase traffic flow, decrease congestion, and improve travel times. It will also decrease the risk of rear-end collisions during stop-and-go conditions, greatly improving driver safety.

In June 2018, WSDOT formed a Technical Advisory Group (TAC), consisting of representatives from area communities and agencies, to provide feedback from their communities and make recommendations on an interchange design for the intersection. Over three meetings, TAC members worked with WSDOT to identify the preliminary preferred alternative using criteria such as safety, local street operations, SR 522 operations and forward compatibility. The TAC reviewed forecasted traffic analysis maps, area development plans, community benefits and impacts and project costs. 


  • 2017 - 2019: Preliminary traffic analysis, concept, design and community engagement.
  • 2025-2029: $10 million in Connecting Washington funding becomes available for continued design work on this intersection and the SR 522 corridor.


  • $750,000 in the 2017-2019 biennium for initial traffic analysis, design work and community engagement.
  • $10 million in funding for initial design work was provided through the 2015 Connecting Washington transportation package. That funding becomes available to WSDOT in 2025.
  • Final project design, right of way acquisition, and project construction are not currently funded.
