Is the A1 at Banbridge the same road as Banbridge town centre’s main shopping street?

No.

The A1 is the through route passing the Banbridge area, while the town centre is reached via its local approach roads. Drivers heading towards Newry or Belfast may stay on the A1 without entering the shopping streets. TrafficWatchNI has an A1 Banbridge camera for general road conditions, but town-centre parking is a separate question. If you are visiting shops, the leisure centre or a car park, use the exact address to identify the correct slip road and approach.
