Not sure if turning the #A14 into the #M14 would be a miracle cure (a Northern bypass for #Ipswich does make more sense, but won't happen overnight) - either would only provide fairly short term gains, they would soon fill up with traffic!
A wider problem is bad #driving during the time pressures of the rush hour - more businesses should adopt flexible working to alleviate this (the lorry drivers are already working 24/7)
