The Woolwich foot tunnel crosses under the River Thames in East London from Woolwich in the Royal Borough of Greenwich to North Woolwich in the London Borough of Newham. The tunnel offers pedestrians and cyclists an alternative way to cross the river when the Woolwich Free Ferry service is not operating. Both entrances to the tunnel are Grade II listed buildings. The south entrance is now somewhat hidden behind the Waterfront leisure centre.
The tunnel was designed by Sir Maurice Fitzmaurice and built by Walter Scott & Middleton for London County Council and opened by Lord Cheylesmore, Chairman of the LCC, on Saturday, 26 October 1912. Its creation owed much to the efforts of working-class politician Will Crooks who had worked in the docks and, after chairing the LCC's Bridges Committee responsible for the tunnel, would later serve as Labour MP for Woolwich.
Greenwich Council started work to upgrade both this tunnel and the Greenwich foot tunnel on 19 April 2010. The works were to reduce leakage, improve drainage and to install new lifts, CCTV, communication facilities and signage, with an original completion date of March 2011. During the works, the tunnel closed on Monday to Friday daytimes, when the Woolwich Free Ferry was available as an alternative crossing.
On 24 September 2010, Greenwich Council closed the Woolwich foot tunnel to all users, due to structural weaknesses discovered in the stairways and tunnel itself. The tunnel was originally expected to re-open in August 2011, but this target was missed.
The tunnel eventually reopened to the public in December 2011, though initially access to the tunnel was only by the stairs until final works on the lifts were completed.
The tunnel has been fitted with a leaky feeder system to permit operation of mobile phones. The tunnel is 504 metres long.
The ‘Friends of Greenwich and Woolwich Foot Tunnels’ (FOGWOFT) was established in September 2013.
In 2016 the Ethos Active Mobility system was installed in the tunnel to monitor and actively manage tunnel usage. The system uses computer vision to count and measure the speed of bicycles and pedestrians, and displays messages on electronic signs to encourage considerate behaviour. The system has also been installed in the Greenwich foot tunnel and aims to make urban shared spaces safer and more pleasant to use for all. The system displays two messages - "No cycling allowed" (in red text) during busy periods, and "Please consider pedestrians" (in green text) during quiet periods.
