§ Mr. Jenkin
To ask the Secretary of State for the Environment, Transport and the Regions if he will list the(a) trunk roads that are carried by a bridge, or which pass through a tunnel, of at least 600 m in length and (b) the dates on which such bridges and tunnels are set to be renewed. 
§ Mr. Hill
In England there are 33 bridges and three tunnels with a length greater than 600 m, carrying 21 different trunk roads. This figure excludes trunk roads transferring to the Greater London Authority in July 2000 as these will be de-trunked.
All these structures have long residual lives and there are no plans for their renewal in the foreseeable future. There is an ongoing programme of works to ensure all structures remain safe and serviceable.
The Secretary of State has made it clear that, in the context of the Transport Bill, he does not have any plans to charge on existing structures that are not already tolled.
I have asked the Chief Executive of the Highways Agency, Mr. Peter Nutt, to write to the hon. Member with a list and place a copy in the Library.
Letter from Peter Nutt to Mr. Bernard Jenkin, dated 6 March 2000:The Parliamentary Under Secretary of State, Keith Hill, has asked me to write in response to your written PQ about trunk road structures of at least 600m in length.I attach a list of those structures. Please contact Gerry Hayter in our Structures Section (telephone 0171 921 4789) if you require any further information on this subject.The table below lists English trunk road bridges over 600m in length1.
