Geotechnical information will be gathered through soil borings to determine soil and groundwater conditions at 13 locations in the project area. Asphalt cores and non-destructive pavement testing will also be done.
Work will be performed on 56th Ave W between 230th and 236th, 232nd and 234th Streets SW between 56th and 58th, and 236th Street SW between 56th and the Transit Center. All borings will take place in existing city right-of-way.
This may result in lane closures, but no detours. Flaggers will direct traffic during the work as necessary. A uniformed police officer will provide traffic control for work in the intersections. This work will be completed the week of July 14.
More information is available by calling Traffic Engineer Janet Hall at 425-744-6275.
