It's official: the Dartford Crossing is the fourth most congested road in the UK.

Only the area around Heathrow and two stretches of road around Birmingham are more traffic-clogged, according to an RAC report.

The study comes just days after the Government revealed the crossing was one of the most affected by delays in the UK.

It revealed a raft of options to ease the bottleneck, including a new Thames crossing and making the toll one-way only.

Typical daily flows range from 145,000 to 150,000, it said.

Now the RAC study reveals nationally we're sick of congestion and poor road conditions - and three out of four drivers want better public transport.

It suggests that almost 90 per cent of motorists are fed up with roads in their area.

But the motoring organisation says only one in five supports the idea of road pricing instead.

According to RAC members the 10 most-congested roads in the UK are:

1 M25 - section from Heathrow airport to M1.

2 M6/M42 interchange - east of Birmingham.

3 M6 - section from Telford to Birmingham.

4 M25 - Dartford Crossing.

5 M4/A4 - approach into west London.

6 M1 - section from Nottingham to Sheffield.

7 A14 - section around Cambridge and Huntingdon.

8 M62 - section around Leeds and Huddersfield.

9 M1 - section north of London through the Home Counties.

10 A406 (North Circular) - section from M1 to M11 in north London.
