To ask the Secretary of State for Transport what are the past and forecast commercial vehicle traffic figures for the M25 through the Dartford tunnel and across the Dartford river crossing for the years 1987 to 2007.

The actual and estimated figures as provided by Dartford River Crossing Ltd.—the crossing operators—for commercial vehicles using the Dartford-Thurrock crossing are as follows:

	Light 000's	Heavy 000's	Total 000's
1987	4,070	2,670	6,740
1988	4,470	2,960	7,430
1989	4,520	3,240	7,760
1990	4,860	3,200	8,060
1991	5,050	3,320	8,370
1992	5,300	3,490	8,790
1993	5,450	3,590	9,040
1994	5,600	3,680	9,280
1995	4,730	3,110	7,840
2000	5,360	3,530	8,890
2005	5,940	3,910	9,850
2010	6,510	4,280	10,790

These assume that the east London river crossing will be open by 1995, with consequential effects on traffic using the Dartford-Thurrock crossing.
