Project Update: Southeast 62nd Street Extension

One year into the Southeast 62nd Street Extension project and crews are past the halfway mark. 

Local residents and passers-by can now see curbs and retaining walls marking the future location of two new roundabouts where 62nd Street intersects 221st Place and Lake Drive. The adjoining bridge alignment over the surrounding wetlands is also visible.

Since our update last summer, crews have completed the following tasks and ensured that the project stays on-track:

  • Crews have constructed a retaining wall adjacent to Issaquah Mini-Storage. The retaining wall slopes upward with the roadway, which will lead to the future east roundabout.
  • Crews have also installed underground utilities, as well as curbs and gutters on the west side of the project in preparation for paving work to begin. 
  • Finally, crews have installed eight piers consisting of 33 piles and set all 35 bridge girders across Issaquah Creek and the North Fork of Issaquah Creek. The longest span is over Issaquah Creek with 127-feet-long, 58-ton girders. These piers and girders will eventually support the deck and driving surface of the finished bridge connecting the two roundabouts.

Coming Up
Coming up in the next few months:

  • Crews will place the bridge deck, install storm vaults on the east end of the project and install new curb, gutters and sidewalk on the west side of the project. 
  • Parts of Pickering Trail will be paved. 
  • Crews will begin construction on the west side of Lake Drive from south to north. Work includes reconstruction of driveways, construction of block walls, underground utilities, curb, gutter and sidewalks, and an interim asphalt road surface. 

As a reminder, construction work will take place from 7 a.m. to 6 p.m. weekdays through mid-September.
