YAKIMA, Wash. — The third phase of construction on the busy 72nd Avenue and Washington Avenue roundabout in Yakima is officially set to begin Monday, July 28.

This stage will see the full closure of the intersection 24 hours a day, seven days a week, starting July 28 and running through September 12.

Detours will route drivers via Nob Hill Boulevard, 64th Avenue, and Occidental Road to help keep traffic flowing while crews carry out extensive underground utility work and paving.

Project officials said the full closure is needed to finish the work safely and “with the least amount of disruption to the public as possible.”

Once Phase 3 wraps up, drivers should regain full access to the new roundabout on September 12, which is a significant milestone — two months ahead of the original completion target of mid-November.

Throughout the closure, access to homes and businesses within the construction zone will be maintained as best as possible, and emergency vehicles will still be permitted through if necessary.

Local drivers are urged to plan ahead for delays and “follow all detours and traffic laws to ensure safety,” city officials emphasized.

While the city expects delays in the area, they recommend using alternate routes whenever possible until the intersection fully reopens.

As with any large-scale road project, the timeline could shift slightly due to weather, equipment issues, or unforeseen circumstances.

This roundabout project is being funded entirely through state grants, which city leaders say has been critical in keeping local taxpayers from shouldering additional costs.

Construction began with Phase 1 back on June 16, followed by Phase 2 on June 30. Phase 4 will follow the completion of this current stage, with final details expected later this year.

Officials continue to thank Yakima residents and local businesses for their patience and cooperation as crews work to deliver a safer, more efficient intersection ahead of schedule.
