Southeast 62nd Street
Southeast 62nd Street


Issaquah is making a major improvement to its northern road network by extending Southeast 62nd Street between 221st Place and Lake Drive (see project map).

The project also:
  • Adds two roundabouts where 62nd Street intersects 221st Place and Lake Drive. 
  • Widens Southeast 62nd Street between East Lake Sammamish Parkway Southeast and 221st Place Southeast.
  • Adds new sidewalks, bike lanes, curbs and gutters, curb ramps and street lights.
  • Makes upgrades along the East Lake Sammamish Trail so that users will no longer have to stop, or interact, with vehicles at Southeast 62nd Street.
  • Preserves close to six acres of property between the north fork and main stem of Issaquah Creek, which were previously zoned for multi-family development.
  • Constructs two acres of wetland.
  • Makes enhancements to the North Fork of Issaquah Creek.

Construction for this complex project, which includes building a bridge, roundabouts and other infrastructure, starts March 2017, and is expected to continue for at least 18 months.
