§ Mr. FearnTo ask the Secretary of State for Transport how many bridges which traverse the London underground network have failed the BD21/84 guidelines; and if he will make a statement.
§ Mr. FreemanI understand from London Underground Ltd. that, as of 26 June 1990, 59 structures carrying highways over its network have failed the criteria of BD21/84.
In all these cases it has notified the highway authorities concerned so that necessary measures can be taken to maintain traffic and safeguard the public.
Strengthening work is in hand on six structures and temporary measures are either in force or being investigated for the rest.
