Methow Valley State Airport (S52) to close for construction

WINTHROP – Methow Valley State Airport will close later this month due to a five million dollar project to replace pavement and maintain infrastructure by the Washington State Department of Transportation (WSDOT) Aviation.

Methow Valley State Airport in Winthrop, where the pavement is 22 years old, is the largest of 16 WSDOT-managed airports.

Wenatchee general contractor, Selland Construction, plans to start the project May 14, which will close the airport to the public.

The Federal Aviation Administration’s (FAA) Airport Improvement Program (AIP), which will fund 90 % of the cost and the WSDOT Aviation will fund 10% of the cost.

There will be three main phases for the project which will include

Phase 1 – Rehabilitate runway 13/31 pavement: Remove existing aged runway pavement, install new stormwater drainage system, new asphalt pavement, and sub-grade improvements for the entire 5,049-foot runway.

Phase 2 - West connector taxiway rehabilitation and widening: Remove an existing forest service non-standard taxiway connector, modify the west side transient ramp taxiway connector to meet current FAA design standards, and taxiway lighting modifications followed by new pavement.

Phase 3 – West apron rehabilitation: Rehabilitate the west side transient parking ramp through additional sub-grade and pavement overlay upgrades.

Phase one and two are scheduled to be completed within the first 45 days. Once the second phase is completed, WSDOT Aviation will open the runway for public use with west side transient ramp access restrictions.

The runway is scheduled to reopen at the end of June, tentatively, in hopes to avoid interference with the expected fire season operations of the United States Forest Service (USFS), conducted by North Cascades Smokejumper Base (NCSB). The NCSB is prepared to operate out of alternative airports until construction is completed.

WSDOT Aviation will issue an airport closure and Notice to Airmen (NOTAM) but the airport’s automated Weather Observing Station (AWOS) will remain operational.

Phase Four, which will expand the west general aviation aircraft parking apron to the south, will be advertised in 2018 for construction in the spring/summer 2019.
