M4 repairs averted 'catastrophic collapse'

Help

Engineers say they had to close the M4 motorway at the weekend for emergency repairs or there could have been a "catastrophic collapse".

Roads Minister Mike Penning said he believed it was now "highly likely" the motorway would reopen on Thursday, although he admitted it would be hugely embarrassing if the route was not completely open in time for the Olympics.

Derek Turner, of the Highways Agency, said it was important the structure was put right as soon as possible.
