Sustainable highways design

Highways England Strategic Design Panel has published its fourth progress and recommendations report.

This report sets out the Panel’s progress over the past year and a half (June 2019 to end of 2020) and makes key recommendations to take forward in the second road period.

The Panel made the following key recommendations, which include:

  • accelerate communication and training to promote and embed its design vision and principles into its processes and culture
  • act on the Panel’s recommendations for adapting to climate change, reducing carbon, supporting biodiversity and the design of corridors
  • publish a design strategy to clearly articulate its ambitions for the second road period and beyond

The Panel is tasked with challenging and supporting Highways England to improve the quality of England’s strategic road network (SRN). The Panel’s role is to make sure that design excellence in landscape, engineering and built environment is considered in all of Highways England projects.

A key recommendation of the report suggests that road planning and design must accept the challenge to create a network resilient to climate change with an emphasis on sustainable design.

The report says: “Roads are long in their planning and long-lasting in operation. Designers must anticipate changes in long-term technological, social and environmental conditions under which they will function well into the future.

“Although it is acknowledged that road use rather than road operation or construction, is currently by far the largest generator of carbon emissions on the network, good planning and design can have a positive impact in all three areas.”

Mike Wilson, Chief Highway Engineer and Chair of the Highways England Strategic Design Panel, said: “The three essential qualities of good road design are safe, functional and elegant. And it is the latter, with careful attention to detail, that will elevate the quality of the network and deliver our vision of good design for people and places.”

Minnie Moll, Chief Executive at Design Council, said: “Infrastructure has the power to connect communities, boost economic growth and enhance the built and natural environment. Of course, this can only be achieved if it is well designed – with people and the planet considered throughout the process.”

The Panel continues to positively influence the design of schemes, and specifically commended the landscape-led design approach of the proposed A417 Missing Link in Gloucestershire. The design of the scheme has embraced the principles of good design and goals of sustainable development to enhance both the character of the place and experience of people.

Advice from design reviews of the A417 Missing Link has encouraged a change in the proposed road’s gradient which will further reduce visual impact and also impacts on local woodland and water courses, waste, traffic, carbon footprint, and construction time, while making cost savings.

Steve Roberts, Lower Thames Crossing, Engineering Design Lead, said: “The advice of the Design Panel was invaluable in the shaping of our scheme proposals, particularly in the early stages of development, helping to define those factors that should influence the design and how the design should respond to its context.

“On a large complex project like Lower Thames Crossing, with significant inter-disciplinary working, the Design Panel, with its broad range of experts, was a useful forum to review the balance of constraints and opportunities within the scheme and the overall level of ambition in our design.”
