A compelling new video has been released showcasing the remarkable progress made on the A417 Missing Link project in Gloucestershire throughout 2025. This footage offers a sweeping aerial perspective on the extensive works underway near Birdlip, where a four-mile dual carriageway is being constructed along with several new bridges and junctions.
The collaboration between National Highways and Kier Construction is clearly evident in the dramatic landscape transformations that have taken place over the last twelve months. One of the standout changes is at Crickley Hill, where major earthworks have significantly reshaped the hillside to accommodate the new road design.
The upgraded A417 will feature three lanes for uphill traffic and two lanes downhill, separated by a central reservation to improve safety and traffic flow. Furthermore, the hill’s steepness is being reduced from 10% to 8%, creating a smoother and safer ascent for drivers.

The video also highlights the emerging Gloucestershire Way Crossing, an environmentally sensitive bridge designed to allow wildlife to cross safely while enhancing the natural landscape. Meanwhile, the Cowley Overbridge is taking shape, promising improved vehicle and pedestrian access across the network.
Additional improvements include the new B4070 link between Barrow Wake and Shab junction, aimed at reducing congestion, lowering pollution levels, and enhancing local access for both residents and visitors. This shift will allow the existing single carriageway stretch between the Air Balloon and Cowley roundabouts to be repurposed as a route for walkers and horse riders.
By alleviating the notorious bottleneck at the Air Balloon roundabout, the project will deliver a seamless dual carriageway connection between the M5 at Brockworth and the M4 at Swindon. The A417 Missing Link is on track to open in spring 2027, promising safer and more reliable journeys across this vital corridor.
