Each year large vehicles collide with overhead bridges. Such collisions endanger lives as well as causing delays on the road and rail networks. A railway bridge collision could also result in the derailment of a train with potentially disastrous consequences.

An interactive map has been produced to inform drivers of high vehicles, or vehicles with high loads, about bridges with less than 16 feet 6 inches (5.03 metres) clearance.

Bridges which are not normally signed have at least 16 feet 6 inches (5.03 metres) of clearance. Only structures with a clearance below this are shown on the following map.

The surrounding signs are used to indicate the maximum headroom of the hazard in both imperial and metric units. DO NOT IGNORE THEM.

Some arch bridges may have a specific headroom over a specific width. This is designated by a white chord on the arch as shown below.

Black and yellow bands may be added to the arches or girders and parapet walls to improve their visual impact. Special road markings may also be used to help guide high vehicles through the highest part of the arch.

The Motor Vehicles (Construction and Use) Regulations (Northern Ireland), state

".... no person shall drive or cause or permit to be driven on a road a motor vehicle with an overall travelling height exceeding 3m unless a notice is displayed in the cab in such a manner that it can be easily read by the driver."

Remember these three simple safety rules:

·Know your HEIGHT

·Know your ROUTE

·Know your SIGNS
