Solution: Protecting
Bridges & Tunnels

Each time a tall vehicle approaches a low bridge or tunnel, or an overweight vehicle crosses an ancient or unstable bridge, there are serious potential consequences for the driver, other transport users and for the infrastructure in question.

There are over 2,000 bridge strikes every year across the UK, estimated as costing taxpayers in excess of £20m a year and causing thousands of hours of train and vehicle delays.

A 2017 RAC Foundation study also revealed that over 3000 bridges in Britain aren’t fit to support the heaviest lorries which can weigh up to 44 tonnes. This is largely due to bridges being built to earlier design standards, while others have deteriorated through age and use.

We have systems to prevent incidents associated with overheight and overweight vehicles and protect both the infrastructure and the road / rail user.

Our vehicle warning systems use sensors to track overheight or overweight vehicles in advance of them reaching the tunnel or bridge that they are too high or too heavy to pass through / under / over. These sensors send a message to a sign that warns the driver and advises them to either stop or take the nominated diversion.

Coeval is a specialist in robust, LED road sign-based systems that advise, inform and educate and are:

more easily noticed by drivers than static signs
visible in all conditions, including at night
flexible to your needs – displaying different speed limits / messages as required
remotely controllable using our Cloud-based software
