Filmed in South Yorkshire. The YouTube comments plumb the depths of ignorance; it's too bad such people can't see the everyday awesomeness of the natural world.
Via Nothing to do with Arbroath.
Addendum: A tip of the hat to an anonymous reader, who in response to my query in the Comment thread asking why this happens, offered a link to a Metabunk post on this subject which has several embedded videos and photos. The discussion indicates that these confluent areas are indeed of arachnid origin, but may not be "webs" in the traditional sense. Rather they may arise from silk spun for "ballooning" (travel) purposes (I probably should change the title of the post):
...there are approximately one million of spiders per acre, (nearly a billion spiders in a square mile) and occasionally a large number of spiders will take to the air ar the same time (probably due to hatching at the same time based on weather conditions). The masses of silk will coat fields, get caught in trees, and sometimes get tangled up and blown into the air...
It was only relatively recently (the 1700s) that people realized the "gossamer" that sometimes coats fields actually came from spider, and was thought to come from evaporated dew...
This silk is not particularly sticky (spiders can spin both sticky and non-sticky silk). But is very light and thin, and when rolled in your fingers it will collapse upon itself, resulting in just a few specks. This can be mis-interpreted as "dissolving", but really it just that the silk occupies very little space to start out with. The silk used for flying is known as "gossamer" silk, and is one the lightest and thinnest of all types of spider silk.
