I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Thelwall Viaduct is a major bridge of the M6 across the Manchester Ship Canal adjacent to two discontiguous segments of a SSSI (Woolston Eyes).
Access is via a footpath from Thelwall.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 29/06/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
They had a competition a few years back for a photo of the church, and as we were staying I put my drone up - as I had permission I wasn’t worried about nosey neighbours or the like, but would have been better if I had crossed the road (so to speak) with the drone.
Should be fine around the area where I flew from in terms of room to TAOL, parking might be the problem.
I cycled all the way up from Thelwall along the footpath, it was maybe a mile and a bit long?
There is a public footpath running from Warrington Road that runs parallel with the viaduct which I think you can walk up, but theres not much room for parking from there.
I used to meet up with a few flyers in Lymm, at Sowbrook playing fields, in case you were after somewhere bigger, plenty of parking, and more open, and you get the viaduct in the distance.
