A startling bit of research this month has shown that almost 2,000 lorries plough into the UK’s bridges every year. One particular bridge in Ely, Cambridgeshire, has been struck 113 times in the last eight years. Apart from the sheer embarrassment for the drivers involved, this is bad news because of the cost attached to clearing up the mess. For a start, there’s the financial burden – £23 million a year – and it’s the taxpayer who picks up the bill. Then, of course, there are the inevitable traffic jams while the stricken lorries are extracted. And, since the majority of the bridges affected carry a railway, an average bridge strike leads to two hours of delays to train services. The message to same day couriers is simple, whatever vehicles they’re driving: know your size.
