To ask the Secretary of State for Transport what information he has as to the changes in transport movements across the Severn bridge in each of the last three years; and what assessment he has made on the effects of price increases.

The following figures are for traffic crossing the bridge westbound from England to Wales:

Period	Number of vehicles (millions)
May 1990 to April 1991	9·3
May 1991 to April 1992	9·5
May 1992 to April 1993	8·8

It is not at present possible to isolate the effects of toll increases. The increases in April 1992 coincided with the introduction of one-way tolling. It is likely that this will have reduced westbound traffic and increased eastbound traffic.Arrangments are in hand to monitor traffic from Wales to England.
