A public consultation for a new £48 million east-west cycle superhighway is currently underway but worries have already been raised over the planned super sewer getting in the way.

The plans would see two way cycle lanes segregated from traffic along the span of the 18-mile route from Tower Hill to Acton.

In west London cyclists would come from Lancaster Gate, along Westbourne Terrace, over Westbourne Bridge by Paddington Station, along the Westway flyover and onto Western Avenue, ending in between North Acton tube station and Acton main line station.

The route would consist of a series of cycle lanes separated from traffic by paved islands which would also provide space for safer bus stops.

It would connect to the existing Cycle Superhighway Route 3 which extends from Tower Hill to Barking in the east.

The consultation launch comes two months after plans were put forward for another cycle superhighway between Oval and Pimlico .

Announcing what he refers to as a 'Crossrail for the bike' Mayor of London Boris Johnson said: “Bikes already make up 24 per cent of all rush-hour traffic in central London – hundreds of thousands of journeys every day that would otherwise be made by car or public transport.

“Because this isn’t just about cyclists. Getting more people on to their bikes will reduce pressure on the road, bus and rail networks, cut pollution, and improve life for everyone, whether or not they cycle themselves.”

Martin Carr, local co-ordinator for the Kensington and Chelsea branch of the London Cycling Campaign also welcomed the proposals.

“I think it is a good thing for London's cyclists,” he said.

“Any good quality cycle lane infrastructure is to be welcomed.”

Mr Carr added he was hopeful the plans would persuade people who may be nervous about the dangers of cycling in London to get on their bikes, and that a successful cycle route through London would lead to further infrastructure changes across the city.

Concerns have however been raised about plans to construct further sections of the Thames Tideway super sewer at Victoria Embankment, and the effect the plans would have on the new superhighway.

It is believed the work, which was given permission two weeks ago to start in 2016 , would require large portions of the superhighway be dug up, despite having only been finished earlier in the year.

The Victoria Embankment Foreshore, just west of the Hungerford Bridge, is part of the sewer, which is designed to divert sewage overflow into subterranean tunnels rather than into the Thames.

The route of the cycle superhighway would run along the north bank of the Thames as far as Parliament Square before winding through St James Park, Green Park and Hyde Park to the Westway at Westbourne Bridge.

Further plans would see the route then extended to Horn Lane in Acton.

It will cross with a proposed north-south route between Kings Cross and Elephant & Castle at Blackfriars Bridge.

Public workshops will be held across London until October 10, with the public consultation closing on November 9 .
