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. 
  • Island Crossing Temporary Signal Replacement:

    • Project start date of January 19, 2021
    • January 19 - The contractors schedule has changed for this week.  They will be doing shoulder work from 8am to 4pm. This will not affect traffic flow. However, please be cautious when traveling in the area.     
    • January 28 -   Next week the contractor will be moving from night work to day work. They will be working from 8am to 4pm Monday through Friday on the shoulders. The work being done should not affect traffic flow, but please be cautious if you are traveling in the project area.
