Have just heard that the footbridge across the Derry Burn, at the foot of Glen Derry in the Cairngorms, was washed away in this morning's rains. Braemr Mountain Rescue Team has a number of photos and videos on their Facebook page -

If you have a trip planned up that way, check the situation before you go and be prepared to be flexible.
