Here’s a shocking truth: billions of pounds invested in smart motorways, yet new reports reveal they’re falling short of their promises. But here’s where it gets controversial—while some argue they’ve improved safety, others claim they’re a dangerous gamble. So, what’s the real story?
Smart motorways were introduced as a revolutionary solution to ease congestion by boosting motorway capacity, using advanced technology to manage traffic flow. Sounds great, right? And this is the part most people miss—not all smart motorways are created equal. The simplest type, controlled motorways, function like traditional motorways but use overhead gantries and variable speed limits to keep traffic moving smoothly. However, two more ambitious schemes—dynamic hard shoulder and all-lane-running—have sparked fierce debate.
Dynamic hard shoulder roads allow drivers to use the hard shoulder during peak times, while all-lane-running schemes eliminate the hard shoulder entirely, turning it into a permanent live lane. Here’s the catch: when a vehicle breaks down on an all-lane-running motorway, drivers must aim for emergency refuge areas, but these aren’t always nearby, leaving some stranded in dangerous live lanes. Edmund King, president of the AA, calls this a “mixed safety record,” pointing out that while controlled motorways are safer, others have seen a rise in fatalities and serious injuries. He labels the current situation “frightening,” as stranded drivers rely on other motorists to notice lane closures in time.
National Highways defends smart motorways, claiming they’ve met safety and environmental goals and prevented congestion on heavily trafficked routes. However, traffic growth has been lower than expected, reducing the number of drivers benefiting from these upgrades. As a result, value for money has been disappointingly low. For instance, a £180 million all-lane-running section of the M25 failed to improve journey times as promised, while a £118 million dynamic hard shoulder section of the M6 near Birmingham only sped up morning commutes, with evening journeys actually slowing down. Both projects are projected to deliver “very poor” value over their 60-year lifespans.
But here’s the twist: National Highways insists smart motorways are among the safest roads, with collision rates lower than conventional motorways. Yet, the AA disputes these claims, criticizing the evaluation methods and highlighting increases in fatalities on sections like the M3 and M1. The Department for Transport has halted new smart motorway projects but maintains they’re as safe—or safer—than the roads they replaced. National Highways cautions that value assessments are based on decade-old projections and may not reflect long-term benefits.
So, are smart motorways a failed experiment or a necessary evil? What do you think? Do the safety improvements outweigh the risks, or is this a costly mistake? Let’s debate—share your thoughts in the comments!
