why is the broughton airbus located in broughton?

Is it because it is close to the motorways [i don`t know which motorways]
close to the River Dee and it has enough land if it needs to be extended? the names of motorways will be useful thanks!
SORRY to be a pain i`m sooooo stuck on these questions

Broughton is near the A55 and the River Dee. You're right about Broughton having enough room to expand.
