Mercer Island Station Construction Nearing Completion

Publish Date

As we head into the fall, work at the Mercer Island Station is ramping up as crews work to put the finishing touches on the station. In the last few months, crews have:

  • Completed installing the platform canopy and glass curtain walls
  • Installed escalators in each head house and begun construction of the station’s bicycle cage
  • Completed installation of the westbound track from the East Channel Bridge to Mercer Island Station

In the coming months, Sound Transit’s systems, signals and electrical contractor will begin installing the overhead catenary system, traction power substations and the signaling system to prepare the station for Blue Line service in 2023. Work will also continue to install track west of the station and in the Mercer Island tunnel.
