A while back they had a seven mile stretch of the Natchez trace closed. Only about a 1000 feet of it was where there was actual construction going on. And the majority of that was shoulder work to support a fifty or sixty foot high embankment that was beginning to slide and endangering the road that above it. The work crews had even barricaded off the work area in such a way to give sufficient room for cyclist to pass through safely.
Those cyclist heeding the road closure notices from google or elsewhere missed out on some of the best weeks of riding on the Natchez Trace unhindered by motor traffic. Indeed the signs on the barricades at both ends specifically said the road was only closed to motor vehicles.
If' I'd not been so
Dangerous, irresponsible
I would have missed out on some great riding.
And I have found other situations since where road closures are perfectly safe for other than motor vehicles and the authorities closing the road agreeing.
