152nd St & 67th Ave N - Culvert Replacement

Description
Completed in 2013

In August 2013, a Public Works Surface Water Management Division project replaced an undersized culvert beneath 67th Avenue, north of 152nd Street, near Marysville. The existing 5-foot concrete box culvert often backed up, causing water to overflow onto the road, disrupting traffic, and damaging the pavement.
Public Works Road Maintenance staff installed a new, 14-foot by 6-foot box culvert under the road. The 52-foot-long culvert included a 3-foot sump to collect sediment and features a permanent flow bybass so crews can complete regular maintenance. The new culvert will reduce the chance of flooding and improve fish passage. 

This is the first phase of a system-wide project that will include upstream and downstream work in the stream channel.

Traffic Impacts
During construction, crews cut through the road to excavate and replace the culvert. 67th Avenue north of 152nd Street closed August 1 for up to three weeks, and drivers used signed detours during the closure. One lane of 152nd Street also closed during construction. Large trucks and oversize vehicles used 132nd Street as a detour route. For more project information, download an informational postcard.

Schedule
Construction began in late July 2013. All lanes of 67th Ave. north of 152nd Street were closed from August 1-21. We coordinated our work with Washington State Department of Transportation's (WSDOT's) project to repave 172nd Street near the Arlington Airport. Visit WSDOT's project page for more information.
