Traffic and Project Updates

  • 204th Street Roundabout:

    • January 19 - Over the next two weeks the traffic control plan will remain in place during working hours while the contractor finishes the ADA ramps, pours the last bit of concrete for the sidewalks and center island apron, paves the west entrance to McDonald’s/Chevron and brings in the topsoil for the landscaping.  At that point the roundabout will be fully functional. Starting in February, the current traffic control plan will be removed, except for occasional work until the weather permits the final paving and installation of permanent striping, and landscape plants. 
    • February 18 - Starting Monday February 22nd, the City’s contractor will begin installing the street lights in the 204th St roundabout area, work is scheduled to be complete by the end of the week. There will be short periods of flagger controlled traffic to accommodate this work. Please be cautious when driving through this work zone and be courteous to the workers. The final paving is still on hold until the weather permits, estimated to be around early spring.

    • Project start date of January 19, 2021
