Project Status:192nd Culvert Photo 2

The City is ready to get construction kicked-off.  Construction activities are anticipated to begin in June and will continue through Fall.  Work will include removal of the old metal culvert, relocation of existing utilities, construction of a new fish-passable concrete box culvert, restoration & stabilization of the stream banks, mitigation of critical areas impacts, and road reconstruction.  The in-stream portion of work must be completed within the allotted ‘fish window’ when fish presence in the stream is at the lowest.  

Anticipated Traffic Impacts

The project will create temporary impacts to vehicle, pedestrian, and bicycle travel on NE 192nd St.  All users are encouraged to use alternate routes during the construction operations

  • Travelers approaching from the north can use 228th St SW to connect between 73rdAve NE/61st Ave NE & 80th Ave NE and avoid the work zone.
  • Travelers approaching from the south can use SR-522/Bothell Way NE to connect between 73rdAve NE/61st Ave NE & 80th Ave NE and avoid the work zone.

Please pay attention and adhere to all temporary signage during construction.  The tentatively scheduled (subject to change) work and traffic impacts are anticipated to be:

  • May – Investigation work; intermittent limited traffic disturbance
  • June – Preliminary site work; regular single-lane closures during daytime hours
  • Mid-July – Culvert and utility placement; full roadway closure & detour plan in place
  • August/September – Road & stream restoration; single-lane closures during daytime hours
  • October – Inspection, clean-up, and closeout; intermittent limited traffic disturbance

  • Remove existing culvert and replace it with a new fish-passable box culvert;
  • Relocate existing utilities and raise road elevation slightly as needed for utilities clearances;
  • Restore disturbed riparian plantings.


  • Add culvert capacity to eliminate flooding caused by Little Swamp Creek at NE 192nd Street;
  • Remove fish barrier;
  • Reduce erosion at culvert outlet.


Originally budgeted as high-flow bypass with Surface Water funds. The City has secured additional King County Flood Control District grant funding to complete the design and construction of the required fish-passable culvert.
