I use…
The A343 to do Ocado Andover (before it caught fire). There are no truck restrictions on it.
I also do Swindon to Amesbury via Marlborough and Tidworth which has no restrictions. If I was going to Andover from Swindon, I’d go through Ludgershall because it’s perfectly for us legal to do so.
I’m at a loss as to how the Co-Op can fine transport firms who haven’t gone though any lorry restrictions. My guess is possibly the hauliers pay because they want to keep the work. I’m also at a loss as to how the Co-Op could fine you if you had gone through weight limit. That’s the police and the local councils job.
It’s also possible that any hauliers engaged in contracts with the Co-Op may well have signed a contract stating using the A303 only but, if that was the case, you’d be told which way to go by your gaffer.
I’m baffled by it too.
