The project is continuing but all work is under careful review in response to the COVID-19 outbreak, and safety measures are in place on site to protect workers, their families and the public.

Highways England strategic road network remains open and they will continue to maintain and develop the network, ensuring that life saving medicine, equipment, supplies and healthcare staff can travel across the country to where they are needed most.

While the contactors continue this key piece of work, they will follow Government safeguarding measures to prevent the spread of COVID-19, and no sites are open to the public​​​​​​​.
