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 in March 2017, and is expected to continue for at least 18 months.

Road & Trail Closures
Several roads and trails near the construction site will be closed to ensure safety onsite, and enable contractors to complete the project faster. 

Please note: The Interstate 90 Undercrossing will be closed (access will remain for the Issaquah Medical Building) from June 2017 until late 2018.


North Fork Issaquah Creek Fish Passage
To improve fish habitat, the Washington State Department of Transportation (WSDOT) is replacing a culvert underneath East Lake Sammamish Parkway Southeast, near the 62nd Street project site. Prepare for project-related lane closures. More information is available via WSDOT.

Businesses Remain Open
During construction, access will remain for all local businesses.
