The Blackwall Tunnel is currently open, with no disruption reported for the tunnel as of now. However, conditions can change quickly following breakdowns, collisions, overheight vehicles or emergency incidents, so drivers should check live traffic information before travelling.
The Blackwall Tunnel remains one of east London’s most important road crossings, carrying traffic beneath the Thames between Greenwich and Tower Hamlets. Because of the volume of vehicles using the A102 corridor, even a short closure or lane restriction can create significant congestion on surrounding routes.
Motorists can check live Blackwall Tunnel traffic and camera updates before setting off, particularly during the weekday morning and evening peaks.
Is the Blackwall Tunnel Closed Today?
At the time of writing, there is no current Blackwall Tunnel closure reported. Drivers should nevertheless treat the status as live information rather than assuming the tunnel will remain open throughout the day.
The Blackwall Tunnel can be particularly vulnerable to disruption because an incident inside either bore may require traffic restrictions while the vehicle or obstruction is removed.
The Blackwall Tunnel live traffic dashboard provides updates along the A102 corridor and nearby camera feeds. JamCams notes that stationary or unusually slow queues approaching the tunnel can be an indication of a breakdown, accident or temporary closure inside the bores.
Why Does the Blackwall Tunnel Close?
Blackwall Tunnel closures generally fall into two categories: planned engineering or maintenance closures and unplanned incidents.
Planned closures have previously allowed engineers to carry out resurfacing, tunnel maintenance, safety improvements and work connected with the Silvertown Tunnel project.
Unexpected restrictions can result from breakdowns, collisions or vehicles that cannot safely pass through the tunnel.
The frequency of disruption is illustrated by a TfL Freedom of Information response covering Blackwall Tunnel closures. TfL said its records from September 2024 to 7 January 2025 encompassed all types of incidents and noted that the tunnel experienced closures nearly every day because of a combination of incidents and planned roadworks.
That does not mean the tunnel was fully closed for an entire day on each occasion. Some incidents or works can involve comparatively short restrictions.
Previous Blackwall Tunnel Closure Dates
A particularly intensive programme of Blackwall Tunnel closures took place during 2024 as TfL prepared road infrastructure for the Silvertown Tunnel.
| Period | Major planned southbound closures |
| January 2024 | 13–15 January; 20–22 January; 27–29 January was designated as a contingency weekend |
| February 2024 | 10–12 February; 24–26 February |
| March 2024 | 23–25 March |
| April 2024 | 13–15 April |
| May 2024 | 18–20 May |
| June 2024 | 1–3 June; 8–10 June; 29 June–1 July |
| July 2024 | 20–22 July |
| August 2024 | 17–19 August |
| October 2024 | Additional overnight works included 11 October and 18 October |
TfL’s January announcement confirmed planned southbound works for the weekends of 13–15 January, 20–22 January, 10–12 February and 24–26 February, with 27–29 January held as a contingency period.
The scheduled March closure was later moved to 23–25 March, followed by another southbound closure on 13–15 April. The work formed part of the new road layout associated with Silvertown Tunnel construction.
Further TfL-announced closures followed on 18–20 May, 1–3 June, 8–10 June and 29 June–1 July. Two further weekends, 20–22 July and 17–19 August, were used for final road configuration, resurfacing and safety-barrier work.
Does the Blackwall Tunnel Close for Routine Maintenance?
Routine maintenance has long been part of Blackwall Tunnel operations. Historically, TfL used Sunday-morning closures to provide safe access for inspection, cleaning and maintenance.
However, drivers should not assume an old weekly or alternate-Sunday timetable automatically applies in 2026. TfL’s published maintenance programme for April 2025 to March 2026 contained individual planned overnight closures, generally using defined maintenance windows rather than providing a permanent timetable extending indefinitely.
For that reason, current TfL information should always take precedence over historical schedules.
Where Can Drivers Go If Blackwall Tunnel Closes?
The most significant change since the major 2024 closures is the opening of the Silvertown Tunnel on 7 April 2025. TfL specifically describes it as an alternative crossing when Blackwall Tunnel needs to close for maintenance or repairs.
Drivers can check Silvertown Tunnel live traffic conditions or monitor the Rotherhithe Tunnel status when considering alternative routes.
Motorists should remember that charges apply to both the Blackwall and Silvertown tunnels between 06:00 and 22:00 each day, except Christmas Day, subject to applicable discounts and exemptions.
What Should Drivers Do Before Travelling?
For anyone relying on Blackwall Tunnel, the safest approach is to check the live tunnel status immediately before departure rather than relying on an older closure calendar. A journey can be affected by an emergency incident even when no planned engineering closure is scheduled.
Checking the Blackwall and Silvertown crossings together can also make it easier to choose an alternative before joining queues on the A102.
