Hallstead / Ulco Airport

The specific reason is not officially documented, but it is almost certainly due to economic factors related to its corporate owner. The airport was privately owned and operated by the Ulster Lime Company (Ulco). The closure likely coincided with the decline or sale of the company, or a corporate decision that a private airstrip was no longer a cost-effective asset.

The airport is permanently closed and abandoned. Satellite imagery of the coordinates reveals the faint but clear outline of the former northwest/southeast runway. The entire site is completely overgrown with grass, shrubs, and small trees, making it unusable for any aviation purposes. There are no remaining structures such as hangars or terminal buildings. The land is currently undeveloped and appears to be slowly returning to a natural state.

Hallstead / Ulco Airport was a private corporate airfield. Its name, 'Ulco', is a portmanteau of the **U**lster **L**ime **Co**mpany, which operated a large quarry nearby. The airport's primary function was to support the company's business operations, likely flying executives, clients, or parts in and out of the area. When active, it featured a single unpaved, turf runway approximately 2,200 feet long. It served general aviation aircraft, typical of small corporate flight departments of the era. Its FAA Location Identifier when active was N89.

There are no known plans or prospects for reopening the Hallstead / Ulco Airport. Given that it has been abandoned for over three decades, its original corporate purpose no longer exists, and the land would require significant clearing and investment to be restored, its revival as an aviation facility is considered highly improbable.
