The proposed Silvertown Tunnel is a four lane road link between Newham’s Royal Docks and the Greenwich Peninsula. The required land in Newham was purchased by TfL years ago, before any formal planning proposal was submitted.
The scheme entered the planning stage in October 2015 and a decision is expected in late-2017.
The case against:
- TfL expects traffic levels to increase by more than a third on major roads across Newham with Silvertown and Canning Town the worst hit.
- More traffic means poorer air quality. Newham residents already suffer the impact of some of the highest levels of air pollution in London.
- The tunnel will bring many more HGVs into East London, endangering pedestrians and people on bikes.
- The earliest possible completion date is 2022/23.
- The Silvertown Tunnel is expected to cost at least £1 billion.
- The tunnel will be tolled, and a toll will also be introduced at Blackwall Tunnel. Whilst West London river crossings will remain free to use – and as those are all bridges, not tunnels, they are available to pedestrians and cyclists too!
- Greenwich Green Party are also concerned about the traffic congestion and air pollution increases this tunnel would cause south of the river. The Woolwich Road flyover is already one of the most polluted spots in London. Furthermore, it will also make existing bottlenecks at Kidbrooke and Eltham – where the A102 and A2 have only two lanes in each direction – worse.
- The tunnel will be financed using Public Private Finance Initiatives – essentially a expensive loan from a private company who also builds the infrastructure. These have crippled the NHS and schools with debt.
The Silvertown/Royal Docks area is already heavily over-polluted, from both the airport and existing building works, we feel TfL’s proposal doesn’t give this harmful impact on local residents and businesses enough consideration. We held an townhall-style event in Britannia Village, near the proposed tunnel’s entrance. Understandably, local residents were angry and felt unheard in the process. Many would prefer a bridge, while others didn’t want any river crossing in the area – as their community was being fractured by all the other approved developments.
In addition to the negative health and infrastructure impacts, this project unfairly targets East Londoners to pay for the privilege of crossing the river, with the introduction of the proposed tolls.
TfL’s proposal claims the tolls are to aid with congestion reduction – but this could, and should, have been thorough trialled at the existing tunnel before public funds are committed to building such an expensive and polluting new tunnel.
It’s also confusing that TfL highlights the continuing need to reduce congestion on these routes, when the argument for building the Silvertown Tunnel was initially to relieve congestion at Blackwall. Is this new tunnel not fit for purpose? Or are the tolls really more about providing a guaranteed revenue stream for the private-partnership funders?
“The Mayor of London is loudly promoting a £750 million Silvertown Tunnel between the Royal Docks and the Greenwich peninsular as the solution to congestion on east London’s roads.
But a simple investigation of the facts shows this scheme to be expensive, unnecessary and dangerous.
TfL admit the only way to stop a tidal wave of extra traffic flooding roads across east London would be to impose toll charges. Motorists would pay around £2.50 to cross the Thames using either the new tunnel or the old Blackwall Tunnel which is currently free.”
Darren Johnson, Green Party London Assembly Member in 2014 , challenged in a Big Debate piece in the Newham Recorder against Newham Councillor Ken Clark, who claimed that “A Gallions bridge and the Silvertown tunnel would reduce the congestion we see in Newham”, without any details on how, or indeed IF, local infrastructure would be improved to deal with the extra traffic these crossings would generate.
Newham has one of the lowest levels of car ownership in London with two thirds of residents commuting by public transport. Newham Green Party believes that residents should have the choice to cross the river on foot or by bike. We welcome new north-south public transport links that would take the strain off current routes.
Caroline Russell, one of Green Party’s London Assembly Members, has also criticised the scheme. She says:
“I will continue to support local people to fight this road tunnel through the planning process and at City Hall I will hold the Mayor to account for his decision to progress this scheme.”

In a recent announcement, Mayor Sadiq Khan attempted to greenwash the project by announcing that buses services through the tunnel would have space for bikes. The Mayor’s support for the Silvertown Tunnel is utterly incompatible with his commitment to reduce air pollution in London.
The Green Party, with locals on both sides of the river, are not the only group campaigning against the tunnel – Hackney, Lewisham and Southwark Councils coming out against it in 2015, and Newham Council in 2016 – after having initially supported it. Greenwich Council gave their support via formal feedback in the second stage of the consultation (Nov. 2015).
There is also an independent group, called No to Silvertown Tunnel, who you can follow on Twitter @NoSilvertownTnl
We’re taking part in the public consultation – several members have responded independently with their views, but we are also preparing an official response from the Newham branch of the party, and welcome feedback from local residents and/or businesses, if they would like it included. Closing date for this final feedback to the consultation is 15th November 2016, therefore we ask for all feedback you would like us to include to be submitted to us by 5pm on Friday 11th November, either in the comments or by email.
