The £2 billion Silvertown Tunnel officially opened today, marking a new route under the River Thames connecting Greenwich to Newham. While hailed by supporters, including London Mayor Sadiq Khan and Transport for London (TfL), as a solution to alleviate congestion at the nearby Blackwall Tunnel, the project has been the subject of heated debate and criticism.

What do supporters say about the Silvertown Tunnel?

Mayor Sadiq Khan and TfL argue that the new tunnel will significantly reduce congestion, enhance cross-river public transport, and improve journey times. The new tunnel includes zero-emission cross-river buses that will make commuting faster and more reliable. This, they claim, will also help address traffic jams around the Blackwall Tunnel and ease the flow of vehicles across the river.

What are the environmental concerns surrounding the Silvertown Tunnel?

However, critics, including environmentalists and climate activists, have raised concerns that the tunnel will exacerbate pollution levels in the area. Increased traffic, particularly from lorries, is expected to lead to higher emissions of nitrogen dioxide, carbon, and particulate matter. This has sparked fears that the tunnel will worsen air quality in a region already struggling with pollution.

How has the Green Party reacted to the Silvertown Tunnel?

Caroline Russell, a Green Party member of the London Assembly, has been a vocal critic of the tunnel. She has campaigned against the project for years, calling the £2 billion investment a waste of money. Russell argues that the tunnel will increase traffic and pollution, detracting from the city’s need for cleaner, more sustainable transport options. She has criticised the tunnel’s cycle shuttle service as “clunky” and impractical, particularly given the dangerous cycling conditions around the tunnel.

What is the Silvertown Tunnel’s impact on cycling and walking infrastructure?

One of the project’s key concessions is a cycle shuttle service, set to run every 12 minutes, seven days a week. This service is designed to help cyclists safely cross the river. However, critics, including Russell, argue that the service is a poor substitute for a dedicated cycling and walking route. She questions the practicality of asking cyclists to dismount, wait for a shuttle, and then load their bikes onto a bus.

How is the Silvertown Tunnel funded and what discounts are available?

The tunnel’s toll system will be in place from 6am to 10pm, seven days a week, and will help manage traffic flow as well as contribute to the cost of building and maintaining the tunnel. Several concessions are available for residents of areas like Bexley, Bromley, Greenwich, Lewisham, and Southwark, with a 50% discount for low-income individuals. NHS staff and patients will have their charges reimbursed, and small businesses in Newham, Tower Hamlets, and Greenwich can apply for discounted off-peak charges.

What’s next for the Silvertown Tunnel project?

The project has been controversial since its approval in 2018, and despite the opening, debates about its environmental and social impact are likely to continue. The Silvertown Tunnel is expected to support growth in southeast and east London, but critics remain concerned that it prioritises vehicle travel over sustainable alternatives.

While the tunnel’s supporters view it as a solution to congestion, critics argue it will simply increase traffic and pollution in the surrounding areas, leaving Londoners with a “traffic nightmare.”
