Somerset County closed the Big Savage Tunnel for the 2024-25 winter season on Wednesday, November 27. This seasonal closure, performed annually, protects the lining of the tunnel from freeze-thaw cycles brought on by high winds, cold temperatures, and wet, snowy conditions at high elevation. Please note that there is no detour, and local roads are narrow and treacherous. Please plan your winter excursions elsewhere on the GAP. The tunnel reopened the afternoon of March 24.
