The Dartford Tunnel is a river crossing on the A282 (not the M25 as commonly believed). It spans the River Thames between Dartford in Kent and Thurrock in Essex, carrying northbound traffic. It is one of the most important river crossings in Britain, and indeed in Europe. The current crossing consists of two tunnels and the Queen Elizabeth II Bridge, a cable stayed bridge. The tunnels were built in stages between 1936 and 1980.
The crossing was originally a single-carriageway tunnel, and carried the name Dartford Tunnel until the opening of the QEII bridge. Initial plans for this tunnel began in the 1920s, with a pilot hole being constructed in 1936 and initial boring works in 1938. As with many other 1930s road projects, work was halted due to the Second World War and work did not resume until 1955.
The tunnel was planned to connect to the "North Orbital" and "South Orbital" roads, which later became Ringway 3, but because the line had not been fixed south of the crossing, there was little choice but to terminate the approach road on the original A2 Dartford Bypass, which was by then heavily congested. The Ministry of Transport and Kent County Council argued over junction arrangements, which were not resolved until early 1963. The tunnel opened to traffic in November of that year. The original toll for cars was 6d.
The tunnel was immediately popular. Although only single carriageway, it was a much higher standard than any other crossing of the Thames east of Tower Bridge, and quickly became the dominant crossing in this area. Consequently, by 1970 there was a strong demand to build a second tunnel, to provide a full dual carriageway link with Ringway 3 and the new Dartford Bypass. Construction on the second tunnel began in 1971, with an original planned opening date of 1976. The project was delayed due to objections at the public enquiry, and finally opened in 1980.
By this time, the M25 as we now know it had been planned, and sections were either open or under construction. The completion of the section south of Swanley resulted in a substantial increase in traffic, to the extent that a third crossing was announced in 1987. This third crossing became the Queen Elizabeth II Bridge, although it is sometimes referred to as the Dartford Bridge. The bridge opened on the 30th October 1991.
The crossing has always been tolled since the first tunnel was constructed. The original toll was 6d for cars. and these days are controversial. Capital repayment of the crossing was completed in 2003 and local opinion was for the tolls to be axed. The tolls became part-time and since 2012 the charge has been free for motorcycles, £2.00 for cars, £2.50 for 2 axle goods vehicles and £5.00 for multi axle goods vehicles. No charges are levied between 10pm and 6am.
As well as manual toll collection, an electronic tag system called DART-Tag was used, which had a transponder in the windscreen and gave a discounted rate of £1.00 for cars, £1.75 for 2 axle goods vehicles and £3.20 for multi axle goods.
The retention of the tolls has been caused further disquiet due to all tolls in Scotland being axed after devolution, making the tolls a significant local issue for Dartford and the surrounding area. However a local resident scheme has been introduced for an annual fee of £10 locals receive a DART-Tag with 50 journeys included in the price, with further journeys charged at 20p. Disabled drivers are exempt from charge but must pre register their vehicle.
From 30th November 2014 onwards, the toll is no longer collected at toll booths at the southern end of the crossing; instead, ANPR cameras record the registration of vehicles using the crossing, and the charge must be paid either in advance or by midnight the day after the crossing, either online, by phone or in certain shops, in a similar arrangement to the Congestion Charge. At this time the tolls were also increased when payment is made afterwards (eg £2.50 for cars), but reduced for payment in advance (£1.67 for cars, increasing to £2.00 from 01.10.2018).
In the very early years, there was a special bus service that ran for bikes, however this wasn't well used so a mini-bus taking the bikes was introduced.
