How does a local ISP physically connect to upstream ISP?

Forgive me if this is a stupid question, but I have little to no knowledge of WAN infrastructure, just looking for some pointers.

So the CE-PE link I understand, in the UK that would be laid by openreach and the PE would live in the local exchange. If the local ISP's next device is 100 miles away what happens in between? Are they running off the national carriers fibre or something?
