It's Saturday today, so I guess the operator doesn't work on weekends and only got this far yesterday afternoon.
It's clear that the trail was freshly graded, but it didn't occur to me that the work might still be in progress. I'm glad now that I chose to hike it here today instead of riding in the soft surface on my bike, which I had considered.
