The UK government has officially scrapped all future plans for smart motorways after years of controversy surrounding their safety, effectiveness, and public confidence. The decision marks a significant shift in national transport strategy and raises questions about the future of road infrastructure.

What are smart motorways?

Smart motorways are sections of road designed to use variable speed limits, overhead signage, and — most controversially — the removal of the traditional hard shoulder to improve traffic flow and reduce congestion. Introduced in the early 2010s, they were intended as a cost-effective alternative to physically expanding the motorway network.

Why are they being scrapped?

A combination of public pressure, safety concerns, and data from fatality reports contributed to the decision to cancel future developments. The lack of a continuous hard shoulder has been cited in numerous high-profile deaths and near-misses.

Transport Secretary Louise Morgan stated: “The safety of motorists is paramount. While some smart motorways have shown promise in congestion reduction, the level of public trust is simply not there.”

What happens to existing smart motorways?

The government has committed to investing £900 million to improve the safety of existing smart motorway stretches. This includes installing more emergency refuge areas (ERAs), upgrading detection technology, and reviewing speed management systems.

• Additional refuge bays every 0.75 miles
• Enhanced stopped vehicle detection systems
• More signage warning drivers of upcoming refuge areas

Industry and public response

Road safety campaigners have welcomed the move. Claire Mercer, whose husband was killed on a smart motorway, said: “This is a victory for common sense, but it should never have come to this.”

Meanwhile, the Road Haulage Association expressed concern about how the decision might affect logistics efficiency and long-term road capacity planning.

“Scrapping smart motorways doesn't solve the congestion problem. We still need a plan for long-term infrastructure resilience,” said RHA policy director James Hookham.

What’s next for UK roads?

With smart motorways off the table, the Department for Transport is expected to focus on traditional widening schemes, junction redesigns, and digital infrastructure upgrades. Pilot programs using AI-based traffic flow prediction and real-time rerouting are already underway in Greater Manchester and the West Midlands.

There’s also renewed interest in green transport corridors, incorporating EV charging infrastructure, solar panels along roadways, and dedicated lanes for autonomous vehicles.

Final thoughts

The cancellation of smart motorway expansion is a landmark decision for British transport policy. It reflects a growing prioritisation of safety and accountability, but also underscores the urgent need for a comprehensive, future-proof road strategy.
