A last ditch attempt to pressure TfL over the controversial Silvertown Tunnel is set to be made by a group of Greenwich Councillors.

A group of “at least 12” councillors are supporting an extraordinary call-in measure to pressure TfL for extra cash because of the potential damage of the £1b tunnel.

A decision is expected on the tunnel, which will connect the peninsula to Silvertown, on May 10, so the decision to review the terms comes at the 11th hour.

Councillor Stephen Brain has spearheaded the pressure, and said he has support from other councillors should they be re-elected.

He said: “A mitigation document recently fell into councillors’ letter trays. I read it and felt the money given to mitigate against noise and air quality is just too low.

“Members can call-in a decision, and it is really unusual at this stage but I felt like I had to do it so it can be reviewed further.

“I’ve gone on the record and said I don’t support the Silvertown Tunnel before now and I have moved to call this in to review the terms with TfL.

“Councillors on the other side of the river in Newham haven’t signed it either.”

Cllr Brain, supported by Councillor Aiden Smith, wants the agreement to be reviewed by the councillors scrutiny committee before it is passed.

The Secretary of State is expected to make a decision on the tunnel in a week’s time – and a report that has been sent to councillors details the legal agreements should be approved.

According to the report, £933,000 will be given to the council for a noise barrier, 41,036 would be given for a bio-diversity plan and £136,000 would be given for school’s road safety.

A further £349,500 would be given for neighbourhood enhancements.

Cllr Brain said: “Really the money is not enough, it’s a pitiful amount. The next step should be to go back to Transport for London before we sign it.”

Greenwich Council supports the construction of the tunnel, despite individual councillors speaking out over the increase in traffic and pollution.

A campaign against the Silvertown Tunnel has been backed by hundreds of residents, and candidates for Peninsula were all grilled on the controversial road at a hustings prior to the election.

Campaigners say the road would only increase the amount of traffic in the area, which has been listed as a pollution hotspot.

TfL says the tunnel would reduce traffic and queueing at the Blackwall Tunnel, improve journey times and allow for extra bus river crossings to support the high levels of growth predicted for both sides of the river.

According to TfL: “The tunnel will also create opportunities for new jobs in the local area, help local employers to access new markets and reduce the environmental impact of traffic congestion.”
