SR 522 - Paradise Lake Road Interchange

Status

July 2017

  • This project received $10 million in design funding in the Connecting Washington transportation package.
  • The State Legislature provided $750,000 in the 2017-2019 biennium for more traffic analysis, design/concept and community engagement. Connecting Washington funding becomes available in 2025.
  • The project has not received any construction funding.
  • Drivers can sign up to receive e-mail updates about work along the SR 522 corridor and other state highways in Snohomish County. 

Overview
We will replace the existing intersection at State Route 522 and Paradise Lake Road in Maltby, just north of Woodinville, with an improved intersection.

Why is WSDOT improving the intersection at SR 522 and Paradise Lake Road?
Improvements will alleviate bottlenecks that occur each day during the morning and afternoon commutes at this intersection in Maltby. It will also reduce the likelihood of rear-end collisions, greatly improving driver safety.

The End Result
We will replace the existing traffic signal with improvements to create smoother transitions between SR 522 and nearby county roads. This will improve traffic flow and driver safety.

Project Benefits

  • Safety: Improvements at SR 522 and Paradise Lake Road will increase traffic flow and decrease congestion. Improving flow will decrease rear-end collisions during stop and go conditions, making the roadway safer for drivers.
  • Congestion Relief: A new interchange means increased flow, which will cut down on drive times and driver frustration.
  • Environment: We will build detention ponds to improve water storage quality. The ponds will collect and filter dirty rain water from the highway before it is released slowly into the adjacent creeks, benefitting salmon and other wildlife. The ponds also reduce the potential for flooding in area creeks.

What is the project timeline?
2017 - 2019: Preliminary traffic analysis, concept, design and community engagement begins.

2025-2029: $10 million in Connecting Washington funding becomes available for continued design work.

Financial Information

  • $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. F
  • Final project design, right of way acquisition, and project construction are not currently funded.
