New mapillary imagery is available for the trail connecting the north and south trailheads at the east end of the canyon.

Thanks for checking on this. The noexit=yes tags did not originate with me, although I must have made this changeset in a way that did not preserve their prior history, unfortunately.

Now that I understand the purpose of noexit=yes, I think the existing access=no on the two westbound creekside paths should be sufficient. The barrier is not a gate. The fence/handrail for the bridge runs from node/5421855127 to node/11232818978 and there are signs on that fence restricting access to the westbound paths behind it.

I can try to get updated Mapillary images next time I am in Chambers Creek.
