The high wind procedures set out on this page are for the safety of bridge users and to minimise disruption to traffic caused by overturned vehicles.

Drivers of restricted vehicles should divert via an alternative route as early as possible – restricted vehicles arriving at the bridges will be turned back by the police. Variable message signs operated by Traffic Scotland warn of restrictions on most approaches to the bridges. Travel bulletins on local and national radio stations also provide regular updates.

It is every driver’s responsibility to consider the safety of their own vehicle and that of other road users. If you are in any doubt, please contact Bridge Control on 0131 319 3083 for advice.
