Lower Thames Crossing timeline

The Lower Thames Crossing timeline spans a considerable time frame so we thought it might be helpful if we break down the whole process for everyone, so that you can follow along with what has gone on, is happening, and we can expect moving forward.

To increasing demand at the Dartford Crossing, the DfT looked at options for an additional crossing at five potential locations (A, B, C, D and E).

The two furthest east (D and E) are ruled out as they are too far from the existing crossing. Rail is also ruled out.

You can view that study here.
The government recognises the need for a new crossing by naming it a top 40 priority project in its National Infrastructure Plan. You can view that report here.
The DfT commissioned a study to assess the 3 remaining location options.
The DfT carries out a public consultation to ask for views on the location of the proposed crossing.

Info on this can be found here.
The response to the consultation confirms the need for a new crossing between Kent, Thurrock and Essex. Option B is ruled out; the remaining two locations (A and C) are investigated further.

Department for Transport (DfT) asks Highways England to assess the economic, traffic, environmental and community impacts for locations A and C.

The 2016 consultation was held from the 26th January through to 24th March 2016.

Despite the fact the DfT asked HE to consultation on Locations A and C, the public consultation asks for feedback on proposals and location C, including 3 routes north of the river in Thurrock and Essex, and two south of the river in Kent.

In TCAG's opinion this consultation was completely biased towards Location C.

It was several weeks into the consultation that we questioned the then Parliamentary Under Secretary of State at Department for Transport, Andrew Jones MP, and he told us “I can confirm that Option A is included within the consultation and remains an option for consideration".  By this time most people had been misled by Highways England into thinking Location A was no longer an option.

The consultation received 47,034 responses from all over the UK and Europe, making it the largest ever public consultation for a UK road project.

The consultation info can be found on HE's website here.

Location C was recommended as HE said it offers far greater economic benefits and congestion relief.
On Weds 12 April 2017, the Secretary of State for Transport at the time, Chris Grayling, announced the preferred route, a tunnel under the River Thames east of Gravesend and Tilbury (location C, route three with the Western Southern Link).

Highways England submitted the LTC Development Consent Order (DCO) on Fri 23rd Oct 2020.

At this time HE chose not to allow the release of the supporting documentation until the application was accepted.

The Planning Inspectorate then had 28 days to decide whether the application was adequate, and whether adequate consultation had been held.

At the eleventh hour on Fri 20th November 2020 it was announced that Highways England had decided to withdraw the LTC DCO application. Had they not have withdrawn the application the Planning Inspectorate (PINS) were due to refuse it.

Highways England announced at this time that they would be resubmitting the DCO application in early 2021. They announced a self set target of resubmission within 90-120 days from when the DCO application was withdrawn. They failed to meet this target.
Highways England held a Community Impacts Consultation running 8 weeks from Weds 14th July through to Weds 8th September 2021.

Whilst National Highways/LTC have not made an official public announcement, we were advised at the December LTC Task Force meeting that there will be another round of LTC consultation in 2022.

We will bring provide more details as they become available.
Since withdrawing the LTC Development Consent Order application in Nov 2020 National Highways/LTC have to date failed to meet any of their self set targets for the resubmission of the DCO application during 2021.

Latest updates are that they currently aim to now resubmit the DCO application in 2022, although no specific date has been announced.
It is estimated that the Development Consent Order (DCO) stage would take around 18 months.

This will include:
  • Submission of the DCO application
  • A decision by the Planning Inspectorate (PINS) as to whether to accept the application
  • A pre-examination stage
  • The examination stage
  • A recommendation by PINS as to whether a DCO should be granted or not
  • The Secretary of State for Transport (currently Grant Shapps MP) deciding and announcing whether the DCO has been granted or not.

There is then also a 6 week window for appeals to be logged if there are legal grounds.  If any appeals are made and accepted then the appeal process is carried out.
According to info released by Highways England in June 2021 they currently predict that, if they are granted a Development Consent Order, according to their current plans construction of the proposed Lower Thames Crossing would begin in 2024.
According to info released by Highways England in June 2021 they currently predict that, if they are granted a Development Consent Order, according to their current plans the proposed Lower Thames Crossing would open in 2029-2030.


Obviously as we have already seen these things are subject to change, and we will do our best to keep this Lower Thames Crossing timeline up to date and things progress.
