Forest Service engineering staff and contractors have restored full access to 167 miles of maintenance level 4 routes (ML4, passenger-vehicle, comfort/paved), restored major functionality on 195 miles of maintenance level 3 routes (ML3, low-clearance passenger vehicle), and improved travel safety across 1,197 miles of maintenance level 2 roads (ML2, all traffic, high-clearance, 4x4) that are critical for community access, forest management operations, and emergency response.

Additional maintenance repair work will take place on Forest Service Roads 6S25 and 6S76 in the Mammoth Pool area. The scheduled work is expected to last from mid-October through the first week of November, making the roads safer and more accessible for everyone.
