Dartford – Thurrock maintenance
The Dartford Crossing, also known as the A282, connects directly at both ends with the M25 London Orbital Motorway, one of the busiest motorways in Europe. Carrying over 50 million vehicles a year, the Dartford Crossing is designed to handle 135,000 vehicles a day, but the average is now 150,000 a day – with the busiest days seeing up to 180,000 vehicles using it. We’re carrying out an extensive programme of repairs and maintenance work over the next several years to keep journeys safe and reliable for road users. To keep disruption to a minimum, we carry out our work overnight, typically between the hours of 10pm and 6am.
The Dartford Crossing carries more than 180,000 vehicles every day.

Upcoming QEII Bridge maintenance
With spring upon us, we’ll soon be resuming our painting work on the QEII Bridge to protect some of its metal components from corrosion.
The painting will take place between April and October, and we’ll be able to do most of it without disrupting traffic. We set up a temporary walkway access for our workers on the offside of the bridge in 2024. This will remain in place over the coming years to provide access to most areas that need painting.
Sometimes, to safely access some of the other areas requiring painting, we’ll need to install overnight lane closures across the bridge between 10pm and 5.30am. One lane will remain open across the bridge for traffic when we need to do this.
Our next full overnight closure of the QEII Bridge, for routine safety inspections and maintenance, is scheduled between 10pm on Saturday 26 April and 5am on Sunday 27 April 2025.

Dartford east tunnel closures
There will be overnight closures of the Dartford east tunnel next week for essential maintenance to the ceiling fans which help ventilate the tunnel.
The adjacent Dartford west tunnel will remain open overnight for vehicles less than 4.8m (15’-9”) high.
Vehicles between 4.8m (15’-9”) and 5.0m (16’-6”) high will be diverted via the M25 clockwise. Important information for drivers of goods vehicles and high-sided vehicles is available: goods vehicles using the Dartford Tunnels
Due to additional M25 clockwise closures on Tuesday 25 and Wednesday 26 March, we will delay closing the east tunnel until 11pm on these dates. This gives high-sided vehicles extra time to use the northbound crossing before closing the tunnel and diversions in place.

QEII Bridge painting work
We’ll be repainting the steelwork of the QEII Bridge over the next five years. This will protect it from corrosion and extend its lifespan.
We’ll also be maintaining the bridge’s pylons, cable stays and associated parts and renewing over 200 bearings.
We’ll install a temporary walkway with a steel safety barrier. This will give our teams safe 24-hour access to the areas where they're working.
We'll need to reduce width of the outer lanes. Inner lanes and the 50mph speed limit across the bridge will remain unchanged.
Using a temporary walkway means we'll need fewer overnight lane closures across the bridge. It will protect our workers, allowing them to work safely and efficiently day and night without affecting traffic
We'll monitor the adjustments to lane widths for three months. If they're working well, we'll keep them in place while we complete our maintenance over the next several years.
We’ll still need full overnight closures of the bridge approximately once every six weeks for routine bridge safety inspections and maintenance.
Please remember that closure details can change at short notice. For the most up-to-date information, please visit our daily closures page.

Bridge re-waterproofing work
We’re re-waterproofing and resurfacing the bridge which carries the M25 anticlockwise carriageway between junction 31 (Lakeside) and junction 30 (A13) throughout July and August 2024.We've made good progress re-waterproofing the hard shoulder across the bridge.
To continue our work, we'll need overnight weekend closures (8pm to 10am) in early August.
Please remember that closure details can change at short notice. For the most up-to-date information, please check our daily closures page.
Project information
Overview
The Dartford Crossing is currently the only way to cross the Thames east of London by road and links the counties of Essex and Kent via the QEII bridge for southbound traffic and two 1.4km-long tunnels for northbound journeys.
The A282 also connects directly at both ends with the M25 London Orbital Motorway, one of the busiest motorways in Europe.
Benefits
To keep this part of the network safe and secure, our work will include:
- Upgrading CCTV and lighting
- Waterproofing
- Maintaining ventilation, electrical and drainage systems
- Replacing tunnel bearings and repairing the concrete tunnel walkways
- Replacing expansion joints on the viaduct
- Replacing the panels which form the tunnel linings
- Carrying out maintenance to the QEII bridge pylons, cable stays and dampers
Additional work will also include:
- Replacing areas of corroded steelwork
- Tile repairs
- Paintwork
We’ll do most of our work overnight to keep disruption to a minimum and planned our work so that multiple schemes can run at the same time.
Diversion routes
Dartford Crossing diversions
- East tunnel – vehicles less than 4.8m (15‘-9”) high will be diverted via the west tunnel. Vehicles between 4.8m (15‘-9”) and 5.0m (16’-6”) high will be diverted via M25 clockwise.
- West tunnel – drivers will be diverted via the east tunnel.
- QEII bridge diversion – southbound traffic will be diverted via the east tunnel. Vehicles less than 4.8m (15‘-9”) high travelling northbound will be able to use the west tunnel as usual and for vehicles between 4.8m (15‘-9”) and 5.0m (16’-6”) high, an alternative diversion will be in place via the M25 clockwise.
