Permit Submittal Update
Apr 30, 2021 - The Mercer Island Transit Interchange is the integration of bus transit service with the Mercer Island East Link Light Rail station that will open for service in 2023.
As a part of the process of bringing East Link Light Rail to Mercer Island, in November 2020 Sound Transit submitted plans to modify City streets to service the Mercer Island Transit Interchange. Prior to the submittal of these plans for permits to move forward with construction, Sound Transit and the City exchanged drafts and comments at the 30%, 60%, and 90% design mileposts.
The permit submittal plans for the transit center and surrounding interchanges are available in the Let's Talk Document Library here (104 pages, 135Mb)
