Dutch Roundabout and Quietways

Description of Works

CONWAY AECOM has worked with the London Borough of Southwark to develop a modern road network, rebalancing the existing car-focused highways to jointly meet the needs of motorists, cyclists and pedestrians, pioneering the creation of an integrated cycling network across the borough.

Two projects that have stood out for the team as exemplars of high-quality, cycle safe design and construction include the Dutch-inspired double roundabout funded by Transport for London (TfL) and the Quietway Network.

The design of Quietway 7 – a five-mile cycle route running from Falmouth Road close to Elephant and Castle to Crystal Palace Park - required major upgrade works at Dulwich Village junction, where the Quietway crosses Dulwich Village, to ensure cyclists can safely and easily navigate this part of the route.

Delivering Innovation

The layout at Dulwich Village junction was a particular hazard for cyclists with the busy routes and tight channels, which then directed both cyclists and motor vehicles along the same route. To address this issue, FM Conway installed cycle friendly street furniture on Court Lane to ensure cyclists had a route they could complete with confidence. By installing dividers on the road, we were able to create two clear, separate routes for cyclists and motor vehicles, and by using flexible, rubber dividers it would mitigate injury if a collision was to occur.

Further changes have also been taking place within the road to remove conflict points. This was achieved with the removal of traffic islands, which were then replaced with pavement buildouts with bicycle bypasses to segregate the cyclists. By segregating cyclists at busy junctions and installing separate traffic signal heads for them, we were able to maximise the safety of all road users by ensuring all traffic indications were communicated clearly and effectively.

Utilising our self-delivery promise, we were able to achieve a significant amount of savings for the client and reduce wastage by reusing a large number of the original kerbs throughout the program. In addition, our surfacing division installed a bespoke zebra crossing outside the school to strengthen the safety of school children and members of the public for the years ahead.

As London’s population continues to boom, making sure we have an extensive cycle network throughout our capital is crucial to combat air pollution and ease pressure on our roads.

Challenges and Solutions

Due to the location of the project, FM Conway had to tailor the scope of works to accommodate the large number of school children who attended a nearby school. Careful planning and phasing of the works were critical to ensuring impact on the public was minimised.

This was achieved with the help of our in-house Traffic Management division who strategically set out temporary road signs, traffic lights and organised lane closures, to allow greater coordination of works. Through active communication we were able to liaise with relevant stakeholders such as the school, shops, Thames Water and TfL to ensure no conflicts were raised and disruptions were avoided.

Jo Barrett, Head of Term contracts at FM Conway, explains:

“The Dulwich Village junction was extremely complex, with many smaller side roads feeding into the main thoroughfare. It was vital that the junctions new design kept navigation clear and straightforward for motorists and cyclists.

“We developed an innovative road layout, which provides a safe space for cycles as well as their own phase in the signals sequence. Working collaboratively with Southwark Council, CONWAY AECOM self-delivered the entire project, from design through to the construction of the road.

“As London’s population continues to boom, making sure we have an extensive cycle network throughout our capital is crucial to combat air pollution and ease pressure on our roads.”


Busy Highway junctions can often pose the greatest challenges for cyclists. Making these safer for all road users has been a priority for CONWAY AECOM and Southwark, who have taken inspiration from the Netherlands, which is famed for its cycling infrastructure.

Jo explains: “Roundabouts can be a hazard for cyclists as the layout funnels bike and motor vehicles along the same route. At Crystal Palace we used roundabouts popular in Holland as our blueprint, adapting the design to meet the needs of the UK road users.

“The roundabouts now segregate cyclists from other traffic. They are channelled around the edge of the roundabout along a separate path, while vehicles are directed around the centre and road crossing are clearly marked for pedestrians.

“The roundabouts are now open to the public and I’m positive they will lead to even greater cyclist numbers in the borough.”

Changes have also been taking place along Southwark’s backstreets, where CONWAY AECOM has been creating a new Quietway network.

Jo added: “Quietway’s are vital to ensuring that as many people as possible are encouraged to get on their bikes. They provide a safe, calm environment for more cautious cyclists, or those who simply want to avoid major routes.”
