We own and maintain five bridges

Abnormal loads

You need an approval from us for  moving an abnormal load through the City of London. We will check your proposed route for low bridges, underground structures, width restrictions, road closures, one way systems and street works.

You need to give us at least three working days notice of your proposals.

You can apply for abnormal load approval and submit your route to us online or by emailing

Technical approval for highway structures

We have a duty to ensure that any structure, new, existing or temporary, that spans across the highway is fit for purpose.

If you are looking to undertake works that could affect the support of the highway, such as basement digging, you will need a technical approval.
