Andover: The A303 is closed from M3 Junction 8 to A34 Bullington Cross. This closure is expected to last for several hours, so be prepared for delays.
If you’re heading west, follow the hollow square signs. Start on the M3 towards Winchester, exit at Junction 9, and take the fourth exit onto the A34 northbound. Then, you can rejoin the A303 at Bullington Cross Interchange.
For those going east, look for the hollow circle signs. Exit Bullington Cross Interchange onto the A34 south towards Winchester, and at the roundabout with the M3, take the first exit to get on the M3 eastbound.
If this closure messes with your plans, give yourself extra time. It might be a good idea to reroute or even delay your trip. You can check out more info on National Highways’ website or use travel apps for updates.
