Essential works to keep the Rotherhithe Tunnel operational could cost as much as £178 million, according to Transport for London.

The expected cost range of the Rotherhithe Tunnel works was revealed this week in a written answer by Mayor of London Sadiq Khan to a question tabled by Liberal Democrat London Assembly member Caroline Pidgeon.

“The renewal of the Rotherhithe Tunnel is currently progressing through concept design and, at this early stage in project development, Transport for London (TfL) estimates that costs will be in the range of £116 million to £178 million, subject to funding being available,” said the Mayor.

“TfL plans to complete the concept design work later in 2020. An updated estimate will then be produced, prior to the appointment of a contractor in 2021 to progress detailed design.

“”In addition to the project activities, TfL will continue regular maintenance and progress any short-term minor renewal work to ensure the tunnel remains safe and operable.”

TfL’s 2019 business plan had put the cost of the Rotherhithe Tunnel works at about £140 million.

Ms Pidgeon also asked the Mayor about TfL’s  plans to fast track proposals for a Rotherhithe to Canary Wharf ferry service if the prospect of regular or long-term closures of the Rotherhithe Tunnel increases.

Mr Khan said that as with the decision to pause plans for a walking and cycling ferry, “full implementation of [the Rotherhithe Tunnel] works is similarly dependent on greater certainty over TfL’s long-term funding position”.

The Mayor added: “I can assure you that the impact of any long-term closures of the Rotherhithe Tunnel on local residents and businesses will be a key consideration in the further development of this work.”

  1. I appreciate that TfL is not in a position to do any real long-term planning at the moment, but we need to know in good time whether there is a risk of an extended closure of the tunnel, and if so what TfL will do to provide alternate transport capacity to cross the river.
