A 'ridiculous' bridge could be the lowest in Britain - with only toddlers able to pass underneath without risking a bump on the head.

       The bridge, located off the M25 near Uxbridge and standing at a mere 30 inches from the ground, is an obstacle course for adults, who must either duck or crawl to traverse it.

       Henry Allum, who runs the YouTube channel Henry's Adventures exploring peculiar locations, believes it's the lowest crossing on a public footpath in Britain, reports MyLondon.

       "It's a bit ridiculous," he said. "I don't think there could possibly be a lower bridge than this."

       In a video posted on his YouTube channel, we see Henry measure the bridge and navigate his way under it. As he crawls through, the bridge does get slightly higher, but he remains hunched over until he reaches the halfway point where he can briefly stand upright.

       In the middle of the two carriageways, he shines a torch into the darkness, showing him standing before having to resume crawling. "Not a good place to go if you don't like spiders," he said.

       The bridge, which spans a path and the River Colne Brooke, rises to 58 inches at the other end - still too low for an average adult to comfortably stand beneath. It can be accessed from a footpath in Uxbridge, west London.

       Viewers have taken to the comments to express their amusement at the video, which was posted in 2021, with one viewer responding: "Just wanted to tell you how much I enjoyed this video."

       Another wrote: "That is hilarious. Wasn't expecting the video to make me laugh, especially the high bit in between the carriageways. Thanks."

       Others were keen to recount their own attempts at navigating this challenging walk.

       Another commenter said: "We found this last year and got half way from the Uxbridge side but Mrs B got claustrophobic and we had to walk back! Great Video as always!"

       And another wrote: "I crawled under that earlier and went 'off piste' nearly ending up in the drink while attached to a large bramble. Keep to the bridleway and avoid this footpath if you have a bad back."

       Henry said he came across the bridge while filming a video on the elusive River Alderbourne, whose access is largely obstructed by private property.

       He's open to suggestions for further exploration, saying: "I did say if someone tells me of a lower bridge in London or the Home Counties I would go and make a video on that bridge too! ".
