Design and Environment
Our Design and Environment team inspect, design and carry out maintenance work on 1222 council owned structures including bridges, culverts and retaining walls.
They maintain Kilmarnock's Multi Storey Car Park and co-ordinate the movement of abnormal load vehicles seeking access across the Council’s road network.
They work closely with our roads maintenance team in all aspects of road and structure maintenance and are also provide input on the design of new roads and realignment of existing roads.
They are also responsible for implementing the new risk-based, plan-led approach to dealing with flooding as introduced by the Flood Risk Management Act (2009) and assist in the maintenance of Girvan Harbour organising the dredging of the harbour on a regular basis to keep it operational.
Hauliers wishing to move an abnormal load must notify
- The Police
- The Roads Authority
- Other bridge owners (such as Transport Scotland and Network Rail)
of the routes that they intend to travel in advance mean that their bridges are being crossed
Design and Environment Information
|What is an abnormal load?
An abnormal load can generally be described as a vehicle
Carrying more than 44 tonnes
With an axle load of more than 11.5 tonnes
More than 3 metres wide
More than 18.75 metres long
The regulations regarding the movement of abnormal loads is contained in the Government Statutory Instrument 2003 No. 1998 - The Road Vehicles (Authorisation of Special Types) (General) Order 2003.
|How much notice do you need to give?
40 to 80 tonnes - 2 working days
80 to 150 tonnes - 5 working days
Over 150 tonnes - a 'special order movement' is needed and they require permission from the Secretary of State.
This is administered through Transport Scotland and Highways England
|How do you notify us?
You can notify East Ayrshire Council and South Ayrshire Council of an abnormal load movement by sending the required details by email to email@example.com
You must also include a standard form of indemnity for any damage that might be caused to infrastructure as a result of the move.
In order to ease the process of abnormal load movements for both hauliers and ourselves, we recommend hauliers to take out an annual block indemnity rather than sending an individual indemnity with each notification.
The haulier is ultimately responsible for ensuring that the route is suitable for the intended abnormal load and will be charged for the removal and reinstatement of any street furniture.
Weight restricted bridges
A number of East Ayrshire Council and South Ayrshire Council bridges are weak and protected by structural weight limits to ensure no damage is caused to them.
A structural weight limit (a round sign with a weight limit only) is a mandatory limit meaning vehicles whose plated weight is over the limit must not be driven over the bridge. These are based on plated vehicle weights and the vehicle is banned even if empty.
Roads can also be restricted by environmental weight limits, applied either to the road on which the bridge lies or to the bridge itself. An environmental weight limit (a weight shown on a lorry on a round sign) is also a mandatory limit, meaning vehicles over the weight limit must not be driven over the road unless they are specifically exempt (often stated in the text plate below the sign).
These restrictions are usually to discourage heavy goods vehicles from using the route as a through route.
This is either for a social or environmental reason, or because the road is unsuitable for heavy goods vehicles.
Height restricted bridges
Bridges, including sign and pipe gantries restrict the available headroom over roads. Only bridges with less than 5.03m (16ft 6in) minimum actual clearance over the carriageway are signed. The signed height denotes the maximum vehicle or load height which can safely travel under the bridge.
On arch bridges, vehicles up to the signed height can safely travel under the bridge on the section of the road which is indicated by the white chord lines on the bridge.
Guidance on the prevention of bridge strikes
Guidance leaflets on how to prevent bridge strikes, designed for commercial drivers and other relevant organisations and businesses, can be found on the government's website.
