Collision between a car and lorry shuts A417 northbound near Cirencester. Expect delays and follow detour.

The A417 northbound is now closed between Cirencester and Gloucester exits due to the car and lorry collision. Traffic is building up in the area.
The closure extends much further north now. Emergency services are there, including the police, and they are handling the situation. Expect delays if you’re driving that way.
They suggest a detour using solid square symbols. Exit the A419 at Burford Road and take the third exit onto the A429. Use the second exit onto the A429 at the next roundabout.
At the first lights, turn left onto A429. Then, go straight at the second lights. At the roundabout, take the first exit onto A40, heading towards Cheltenham.
Finally, turn left onto A436 towards Gloucester at lights. At Air Balloon Roundabout, take the second exit, which rejoins you onto the A417 again. Plan extra time because of this.
