We monitor the route and movement of heavy and wide abnormal loads through the borough and advise haulage operators on the best routes to follow in order to avoid crossing weak bridges. When hauliers wish to move heavy loads, this is classed as 'abnormal' (for example those with a gross weight exceeding 40 tonnes).
Before a haulier can move an abnormal load, they must notify and gain consent from the police. In addition, if the gross weight or axle weights exceed those specified on the C and U regulations he must indemnify the Highway Authority and all bridge owners along the proposed route (e.g. Network Rail).
An abnormal load can potentially go on any road provided the haulier complies with the law.
The law requires the haulier to give a minimum of two clear days notice to the police, highway authority and bridge owners before moving the load.
The notice period for loads over 150 tonnes, 6.1 metres wide or 27.4 metres long is different and hauliers moving such loads need special orders from the Department of Transport.
For full details of the notification requirements for large and heavy loads, visit the Hounslow Highways Agency website.
