Could have been; the Titan crane is still there. I found information on the internet about structures radiused out from runway ends a few years ago when the discussion about a Central Scotland airport was running. It's still on my map and the runway end needed to be 1600 Mtrs from a row of quite high electricity pylons.
The Titan is 2000 Mtrs. from the threshold of 25. I also remember a business in Rothesay Dock having a planning problem over a silo or something they wanted to erect, it was only a few years ago.
From your earlier post Abbotsinch Rd. is only 180 Mtrs. from the runway centreline at the bend approaching the junction between the bridges. This is getting close to the safe distance, which was/is 150mtrs? It is over 200mtrs. at the threshold.
