WARREN â The USDA Forest Service would like to remind snowmobile enthusiasts of the important changes in snowmobile trail access for the 2020-2021 winter season on the Allegheny National Forest. The main Allegheny Snowmobile Loop (ASL) is closed from the intersection of FR 120 and FR 141 to the intersection of FR 262 (Longhouse Scenic Byway) and SR 321 for the season. ASL Connector 19 (Longhouse Scenic Byway), from SR 59 to SR 321 is also closed for the season. A current map showing the closures is be available at: https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5052705.pdf These closures are the result of road construction on FR 262 this winter. We regret the inconvenience to our snowmobiling enthusiasts, but it will NOT be possible to ride the entire Loop this season.
