Clyde to Cromwell cycleway

Is it a bridge or an outrigger or what is it called? Whatever, but it is part of the cycleway where the rocks cannot be dug out to make a trail so a construction is tacked onto the rocks. There are a number of these on the 50kms or so trail and this part is probably about 30metres long. To the right you can just see the track and on the left the track still needs to be formed. Looks flimsy, doesn't it. The trail is well underway and should be finished early next year which is a month later than first hoped but this is another result of lockdown. It is quite a feat of engineering.
