Overview Map

PSE is currently considering four route options: Oak 1, Willow 1, Oak 2 and Willow 2. PSE’s preferred route is Willow 2. Click here for more information on the preferred route.

Route options are composed of different route segment combinations and will connect substations in Redmond, Bellevue and Renton.

In April 2016, PSE updated the project route maps to align with how the EIS refers to the project routes. 

Specifically, the update incorporates the below adjustments:

  • Segment 1 runs from the Sammamish substation in Redmond to the Lakeside substation in Bellevue, north of Interstate 90. Segment 1 is the same for all route options. This Segment includes the former Segments A, C and E.
  • Segment 2 runs from the Lakeside substation in Bellevue north of Interstate 90 to just south of Forest Drive SE in south Bellevue. Route options differ in Segment 2. This Segment includes the former Segments G2, I, J, K2, O, and P.
  • Segment 3 runs from just south of Forest Drive SE in south Bellevue to Talbot Hill substation in Renton. Segment 3 is the same for all route options. This Segment includes the former Segments M and N.

Note: PSE is also exploring two ‘bypass’ route options.
