I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
I parked on Parsonage Road, Widnes. A public footpath runs west under the two bridges, and there is an open concrete area on the river bank at https://what3words.com/camps.crowned.safely where I took off from.
Hazards: this site is clear of the Liverpool Airport flight restriction zone (at date of flying), but note that DJI's no-fly zone extends across much of the river (height limit of 60m imposed unless you arrange a temporary unlock). The footpath was not busy when I flew (Saturday morning). The take-off point is >150m clear from housing and from the road/rail bridges, but note there are commercial buildings and a school playing field nearby. Also: seagulls!
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 07/03/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
