Plans for multi-billion pound tunnel under the Thames

Plans for a new multi-billion tunnel under the Thames to link Essex and Kent have been shortlisted along with a new junction on the M25.

It would be the first new crossing of the Thames east of London since the Queen Elizabeth II bridge opened 25 years ago and it is aimed at easing pressure on the Dartford Crossing.

After looking at various options, Highways England is recommending a tunnel from East Tilbury in Essex under the river to Chalk in Kent.

A new junction would be built on the M25 between junctions 29 and 30 with a road leading through to Orsett and then onto the new tunnel.

There is no timetable for when the new crossing would be built and it is estimated to cost £1.2 to £3.4 billion.

The proposals are now open to consultation.

Although Highways England has put forward its recommended option, there are other routes being consulted on including three in Essex.

There will be 24 public exhibitions held at venues across Kent and Essex and consultation will be open until 24 March 2016.

Highways England says all responses will be taken into consideration before a final decision is made by the Government later this year.
