A417 Road Closure: What You Need to Know (2026)

Major Road Closure Alert: A417 Shuts Down for Four Weeks – Here’s What You Need to Know

If you’re a regular traveler on the A417 in Gloucestershire, brace yourself for some significant changes ahead. But here’s where it gets tricky: the road is closing for four weeks, and it’s not just a minor inconvenience. This closure is part of a massive £460 million project to transform the A417 Missing Link into a modern dual carriageway, connecting Brockworth bypass and Cowley Roundabout. While this upgrade promises smoother journeys in the future, the present is about to get a bit bumpy.

The Backstory: A Long-Awaited Transformation

For nearly three years, work has been underway to replace the old single-lane carriageway with a four-mile dual carriageway. The project got the official go-ahead in November 2022, marking a major milestone for Gloucestershire’s infrastructure. And this is the part most people miss: the closure isn’t just about laying new asphalt—it’s about reshaping how we travel across the region. But with progress comes disruption, and this is where things get interesting.

What’s Happening and When?

  1. Overnight Closures in February and March: The A417 will be closed overnight and on weekends throughout these months, affecting both local and long-distance journeys.
  2. Four-Week Full Closure: From February 16 to March 13, the A417 will be shut in both directions between the A46 Brockworth junction and the Air Balloon Roundabout, Monday to Friday, from 9 pm to 6 am. Controversial point: While daytime travel remains unaffected, this overnight closure could impact late-night commuters and delivery services. What do you think—is this the best time for such a closure?
  3. Pedestrian Access Restricted: During the closure, pedestrians won’t be able to use the route between Brockworth junction and the Air Balloon Roundabout. However, other walking routes remain open.
  4. A436 Weekend Closures: In March, the A436 will also close for two weekends between the Air Balloon roundabout and the Seven Springs roundabout. These closures will run from March 6-9 and March 20-23, 9 pm to 6 am.

Diversions and Alternatives

Full diversion routes are available here, but it’s worth planning ahead. Access to Cirencester via the A417, Leckhampton Hill, and the A436 will remain open through the Air Balloon Roundabout, including entry to Crickley Hill Country Park. Thought-provoking question: With these diversions in place, will the closures cause more frustration than anticipated, or are they a necessary evil for long-term benefits?

Looking Ahead: A Brighter Future?

While the closures may test our patience, the end goal is a faster, safer, and more efficient road network. The A417 Missing Link project is a game-changer for Gloucestershire, but it’s also a reminder that progress often comes with growing pains. Final question for you: Is the temporary inconvenience worth the permanent improvement? Share your thoughts in the comments—we’d love to hear your take on this transformative project!
