Dynamic Hard Shoulder enhancements
Improving journeys on older smart motorways
National Highways is delivering a series of enhancements to sections of dynamic hard shoulder motorways across the country.
‘Dynamic hard shoulder’ (DHS) is an older form of motorway where the hard shoulder is turned on and off as a traffic lane in response to traffic flow.
Plans to convert these sections of motorway to the latest All Lane Running standard have been paused, while we consider alternative ways in which to operate the dynamic hard shoulder.
In the meantime we will be installing further safety measures where DHS motorways are in operation, including upgrading the central reservation barrier.
The work is part National Highways’ commitment to make England’s smart motorways even safer and improve confidence in them.
You can see more information on our smart motorway evidence stocktake page.
About our roadworks
We will always try and choose the best and least disruptive way of delivering these upgrades.
Where we are upgrading safety barriers, there will be narrow lanes and a reduced speed limit. Any additional restructions will be limited to overnight or at weekends when traffic volumes are lowest.
We will carefully consider what roadworks will be required at each location and we will make sure we publicise details in advance.
There are seven sections of dynamic hard shoulder across the country, covering 63 miles of road.
