Proposed Construction hours/routes

As part of the Supplementary Consultation Highways England provided more details on the proposed construction hours/routes for the Lower Thames Crossing, if it goes ahead, and it’s not good.

To begin with it is important to stress that construction work cannot legally begin until such time that Highways England are granted a Development Consent Order for the Lower Thames Crossing, which they haven’t even applied for yet.

Please be aware there is a newer update on the newly proposed 24/7 construction hours in new areas all along the route, not just the tunnels – https://www.thamescrossingactiongroup.com/new-24-7-construction-hours/ 
Proposed Construction Hours

Let’s start by stating that they are predicting that construction of the whole route will take around 6 years. If they run to schedule, we all know how these projects overrun!


Tunneling would be 24 hours 7 days per week for around 4.5 to 5 years.


Along the rest of the route they are proposing work hours to fit in with available daylight. This would mean the length of their working day will change as the daylight hours change through the seasons.

They are planning to carry out most of the work between:

  • 7am – 7pm and when daylight allows 7am and 10pm Mon-Fri (exc Bank Holidays) 
  • 7am-4pm on Saturdays
  • From time to time they may have to carry out maintenance work on Sundays

However, they also state that crews may work for up to 1 hour before and after to prepare and close the site.


  • This means we could have people working on construction sites from 6am-11pm Mon – Fri and 6am-5pm Saturdays, and some work on Sundays.


They comment that with a project of this scale, some work would have to take place at night and on weekends.

Details about Construction start on page 100 in the Supplementary Consultation Guide.
