Transport for LondonBlackwall Tunnel refurbishment
The tunnel re-opened to full service on 11 November 2011 after works to bring the 114-year-old tunnel up to date finished more than a year ahead of schedule.
An additional lane for HGV vehicles on the northbound approach to the tunnel will help us divert over-height vehicles away from the tunnel before they reach the entrance.
Other improvements include:
- Better emergency access for maintenance, more emergency points and improved escape route signs
- Upgrades to CCTV, ventilation, drainage, fire mains and hydrants
- Improved detectors for smoke, stopped vehicles, pedestrians debris and over-height vehicles
- New lighting and communications systems
- Automated tunnel closure system
- Variable message and lane control signs
