Project Status:

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 192^nd St.  All users are encouraged to use alternate routes during the construction operations. 

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