Britain’s pothole problem is no quick fix | Letters

Edward Leigh says there must be no cutting corners when rebuilding roads; Anthony Millett says if you are going to do something, do it once and do it properly
Esther Addley (The pothole puzzle: the bumpy ride to fixing Britain’s broken roads, 23 May) quotes Phill Wheat, a professor of transport econometrics at the University of Leeds, describing the “spiral that we could get into” if funding for road maintenance is not increased. In truth, many highway authorities are already well down that spiral.
Once holes and cracks start appearing in a road, they grow and proliferate quickly. Vehicle wheels act like jackhammers around every bump and dip. Once the surface starts breaking up and water loosens the lower layers of the road structure, the opportunity to dress or replace the surface soon passes, and rebuilding at much greater expense becomes unavoidable. So repair costs rise rapidly in the short term and multiply in the long term.
