- On Saturday November 21st, the City's contractor, Reece Construction will be working to pour the concrete for the center island. Please expect small delays when traveling in the area.
- Depending on weather, you should start to see many changes on the south side of the intersection over the next few weeks. The contractor will start installing the 204th Street road base, the concrete flat work (sidewalks, curbs and ADA ramps), and the south portion of the roundabout island. Starting next week a truck detour route will be put in place for trucks heading east bound on 204th Street. This detour must stay in place until the contractor pours the south side roundabout apron and it cures (hardens) for a minimum of seven days.
- Reece Construction will be pouring the curb, gutter, and center apron on the south side of 204th tomorrow 12/29. Please expect delays during this process. Large trucks will not be permitted to travel east bound on 204th until the apron is fully cured (approximately one week). Delivery trucks will be allowed to access businesses on 77th Ave with a right in/right out only. Please see truck detour map for alternative routes.
- December 30 - The contractor is pouring the splitter islands on 77th Ave and the east side of the 204th roundabout today, and re-pouring the center island curb and gutter. There will be flaggers onsite over night to help assist trucks with the detour.
- On Thursday January 7th the City's contractor will be pouring the south side curb replacement and sidewalks. Large trucks please continue to use the truck detour map until notified.
- January 11 - This week at the 204thSt Roundabout project, the City’s contractor Reece Construction, will be doing the following work (weather dependent):
- Tuesday - asphalt grinding and roadway preparation, Wednesday – pave the base layer of roadway, Thursday – install temporary striping
- January 15 - Reece construction will be working today and Monday, January 18th to finish up concrete work. Traffic Control will be in effect. Please expect delays when traveling in this area.
- 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.

- 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.
