There has to be some rational reason why lorry drivers bash into Grantham bridges on a weekly basis, bringing the town to a standstill.

Here are the popular theories:

1. Drivers are blindly following instructions by Sat Navs.

2.They're STOOPID.

3. The signs might be wrong ...

So the Journal and Grantham Business Club co-chairman Wade Rowlett decided to measure the bridges to make sure the warning signs are correct.

Wade, a qualified surveyor and fellow of the Chartered Institute of Building, used an electronic measuring laser to check the height of the bridges.

And we found they're all TALLER than it says on the warning
signs.

So there really is no excuse to hit them, unless, of course, you count being totally STOOPID.

The Journal launched the It's a Low Bridge Stoopid Campaign to stop drivers ploughing into bridges in Springfield Road, Harlaxton Road and Barrowby Road.

All three are on Network Rail's list of the top ten most hit every year, causing huge disruption for road and rail users.

Earlier this year, after abandoning plans to carry out a feasibility study into ways of protecting the bridges, Network Rail added huge reflective warning signs to warn drivers.

But that hasn't prevented regular impacts by drivers
who don't know the height of their vehicles.

Each time a bridge is struck, we write to the companies involved to
give them tips on how to prevent it happening again - a move commended
by the Road haulage Association.

Lincolnshire County Council says it plans to improve signage on the approach to the bridges.

But despite this being a problem which has dogged the town for years, they say it is not yet known when the work will be done or how much it will cost.
