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 a haulier wishes to move heavy loads, this is classed as 'abnormal' (for example, a load with a gross weight exceeding 40 tonnes).
Getting consent
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, the haulier must indemnify the Highway Authority and all bridge owners along the proposed route (for example, 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 is different for loads over either:
- 150 tonnes
- 6.1 metres wide
- 27.4 metres long
Hauliers moving such loads need special orders from the Department of Transport.
For full details of the notification requirements for large and heavy loads, see: Hounslow Highways website - Abnormal loads.
