Drivers using the new Mersey Gateway bridge have been fined between £3m and £1m in penalty notices during its first month of operation.The Liverpool Echo reports that 50,000 penalty charge notices (PCNs) were issued during the period October 14 to November 14 and that if every one of those people paid the standard £40 PCN, the bridge's owners would receive £2m.It adds that those who pay within 14 days will see the cost drop to £20, while those who leave it longer than 28 days to pay or make representations can see their fines rise to £60. If everyone paid the lesser level the total cost of fines for the month would come to £1m while the higher fine would bring it to £3m.A representative of the Mersey Gateway Crossing Board (MGCB) told the newspaper the first month was "untypical" and should not be used to make long term forecasts.The spokeswoman added that fines levied would go towards the £1.86bn project's construction and maintenance costs and that drivers had made more than two million crossings on the Mersey Gateway in the first month and 95% of users paid on time.
