Abnormal loads and ESDAL routes.
Abnormal load route assessments for solar, battery, wind and industrial schemes: finding a route that works and setting out what the haulier and authorities need.
Also known as: abnormal load, ESDAL, abnormal indivisible load, AIL route survey, wind turbine transport
What’s included.
Transformers, turbine components and large plant often travel as abnormal indivisible loads. Hauliers notify police, highway and bridge authorities, usually through National Highways’ ESDAL system. At planning stage, the council needs confidence that a workable route exists.
- Route options from port or depot to site
- Swept path checks at pinch points
- Street furniture, verges and overhead constraints
- Bridge and structure flags
- Temporary works and traffic management
- Input to the Construction Traffic Management Plan
Straightforward, proportionate, agreed early.
Route first
We identify a workable route early, before the layout and the programme depend on it.
Tracked
Swept paths at the tight points, so temporary works are known and costed.
Joined up
The route feeds straight into the CTMP and the conditions.
Questions we get asked
What is ESDAL?
ESDAL is National Highways’ Electronic Service Delivery for Abnormal Loads system, used by hauliers to plan routes and notify the relevant authorities.
Who notifies the authorities?
The haulier, before each movement. At planning stage, we show that a workable route exists.
Do you handle renewable energy schemes?
Yes. Solar, battery and wind schemes often raise abnormal load questions on rural roads.
