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.

2 M6/M42 interchange - east of Birmingham.

3 M6 - section from Telford to Birmingham.
