Assuming you aren't a troll.

Manhattan - like most US cities have streets/avenues based on a regular grid and numbered consecutively Streets East/West and Avenues North/South.

So you can continue the numbering scheme across the entire world. The angles are due to the fact that the streets are aligned with the island of Manhattan rather than geographic north.

I live in a city with a street plan defined by an irrigation ditch cut around 1300AD and a market place that was active 1150 AD or so. Other places nearby have main streets surveyed originally by the Romans.

I suspect this was not a troll.

Greetings from very near 10137Ave, 62586st, bluenose territory.

The original main street in this city was pretty much defined by the 12,000 year old glaciated tail behind the crag of a 350 million year old volcano. :-)

No, I'm not a troll. I had never imagined this before, very cool!
