Glendale announced a nearly $2 million grant from the Arizona Department of Transportation to fund a 1-inch asphalt overlay on the city airport runway, a city spokesperson said. The upgrade is expected to extend the runway’s life by at least 10 years and will require the airfield to close during construction.

The overlay will be a 1-inch asphalt layer, paid in part with the ADOT grant, city officials said. City staff are coordinating with airport tenants and nearby businesses to plan around disruptions caused by the temporary closure. The city did not specify construction dates or a timeline for reopening.

The city described the project as a lifecycle extension for the runway. Details about the contractor, specific closure dates and any alternate arrangements for affected tenants were not specified in the announcement. The city said it will provide updates as scheduling and logistics are finalized.
