Driving tonight, which autoroute?!?

[Becgaz]

I! We set off tonight (our ferry is at 4:20 tomorrow morning!) and we drove from Sheffield to London yesterday to break up the trip for the kids. We've just realised we've forgotten to borrow my mums European sat nav!
I know is basically only 1 road to the magic but I can't seem to find anywhere which number autoroute it is! We're traveling from Calais.
We're so very excited now, just hope the weather is better than it looks on my app!
Thank you to anyone that can help. X

Thanks for coming to my aid yet again!
I'm sure we'll be fine, my DH is just worrying we'll get lost.
I'm not so worried about the temperature, its just the rain but we're going to have a fabulous time regardless!

Also, you need the A26 from Calais to get onto the A1.
