The key to the confusing house numbering is that when a long road crosses between multiple towns, the numbers start again from 1.

So, to achieve the proximity effect, you want to find two towns which are close together, but which have expanded to form a continuous conurbation.

You then need a road which either 'clips' one of these towns, and hence has numbers starting from 1 but then quickly moves to another town, where the numbers get reset, or, where the road starts just over the border into one town, and hence again, starts from 1 before quickly crossing into another town.

We live in the UK city of Brighton. Actually, Brighton had a neighbouring town, Hove, and the two councils merged in the 90s to form 'Brighton and Hove' but this is often abbreviated to Brighton, and this town became a city in 2000.

So, any road that crosses between Brighton and Hove will have this number reset problem. We happen to live 200 yards from the Brighton and Hove 'border' for want of a better name, and our road crosses, so we have another identically numbered house on the same road 400 yards away.

The road itself runs for a number of miles, so there is at least one other house with the same address that I know of (in Portslade, the next town along). We occasionally get confused delivery drivers and post from the postman where we try and work out from the address who the package is for. I've met the current owners of the other two similar addresses, so we can help point things in the right direction.

Is it common for the name of the street not to change when entering a new municipality?

Because in .nl, I know this happens and I'm pretty sure this is the common thing for major roads connecting small hubs. Actually, a road connecting village A to hamlet B would typically be called "A'seweg" (A road) in B and "B'seweg" (B road) in A. If they go through and connect more municipalities, they might become a numbered road (eg, N281), but that you cannot use in an address.

It does seem to be a common pattern here, that the old roads tend to name where they are going (which obviously only works in one direction!). For example, we have a 'London Road' which starts in the middle of Brighton, and takes you to London, which is 50 miles away.

We also have quite a number of roman roads, although not that many around where we live, which criss cross the country, and can travel for hundreds of miles, for example, the Fosse Way, here's google's name match, but if you zoom in on sections of this, you can see the fairly straight roman road with different 'B' road numbers (but still called Fosse Way):

And naturally enough, at the London end (e.g. in Croydon), it's named 'Brighton Road'.
