Just been on the North M25 (between M40 and A10) in the UK and narrowly missed several deep potholes that could easily have you off. Surprised to see that on a Motorway class road. Take care, especially at night.
https://www.fixmystreet.com/ I have used this several times. There was a large hole developing on the M40 that I reported and was fixed within a week Other reports I have logged have gone completely unanswered and even 'missing' later when I check on them
I reported about fifteen potholes to my local council last year and they all got filled. Sadly, this year they have all opened up again and are worse than they were last year.
This is the problem, they just chuck a bit of tarmac in and it’s just churned up again in no time. I’ve even seen the council around here filling holes in the rain. There’s a road near me which is frankly dangerous, especially at night, and it’s a major thoroughfare although only a B road. The council have filled holes on it which have only lasted a matter of days before they’re holes again.
