Britain's pothole problem deepens - Telegraph Edmund King, AA president, said: "This spring our patrols are telling us that potholes are popping up faster than daffodils. This reflects the effects of very wet and frosty weather on poor road surfaces. He added: "What is even more worrying is the fact that the new 2013 Asphalt Industry Alliance 'Alarm Survey' reveals the scale of the problem from a local authority perspective and things look particularly bleak, with more potholes, a bigger maintenance backlog and less cash. Ring-fenced finance must be found to plug an increasing gap in highway budgets - otherwise drivers and local authorities will end up paying more to repair damage that could have been prevented. We urge drivers to report potholes to highways authorities to allow them to take action and prevent road users from being endangered and their vehicles suffering damage. A recent report by the campaign website, potholes.co.uk, also revealed that potholes are increasing not just in quantity but size too. Its study used data from more than 10,000 pothole reports, and found that the average depth of a pothole had increased from 3in to 4in in the last two years. It says that with 2012 being the second-wettest since records began, plus the freezing winter conditions, it's no surprise that potholes, which are caused when moisture seeps into cracks in the road surface and then freezes, thus expanding and cracking the road, are worse than ever. However, Duncan McClure Fisher, managing director of Warranty Direct, which is behind the potholes.co.uk website, believes it is not the weather at fault: "The pothole epidemic is the direct result of years of under-investment in our roads by the Government. Temporary fixes have just escalated the problem over the years and our highways have now got more holes than Swiss cheese," he said. How to report a pothole: Honest John, the Telegraph's Motoring expert, advises motorists to report potholes to potholes.co.uk or fixmystreet.co.uk. These websites will report the potholes to the relevant local authorities, and monitor the report until the pothole has been repaired. Furthermore, by reporting a pothole to either of these sites, it becomes a matter of record, which is actionable. These sites work too, as one Honest John reader recently reported: "I have reported more than 500 potholes via fixmystreet.co.uk (easy with an iPhone app). They have all been fixed apart from one, which I am chasing. If everyone reported this scourge, drivers would suffer less vehicle damage," they said.
