What is the highest street or Ave in a city?

I don’t know. However, some rural areas in the USA use street numbers based on the largest nearby city, even though they are not in that city.

For example, according to “mgk920”, “There is a 1010th Rd along WI 29 (or old WI 29) a short distance west of Chippewa Falls, WI.” (From this similar question on Google Groups.)

I’d guess somewhere in La Paz, Bolivia?

Just read @Zaku’s answer and realize I interpreted this question very differently!

The highest number I ever saw was in Edmonton Alberta. 215 street.

986039 Oxford-Perth Road

Oh wait. Missed the question again. This is the highest address. Not highest numbered street!

Highest numbered street (not altitude, not address) that I’ve found so far is E 3000th St in Clayton, IL.

Like @Zaku said, not in a city. But tied into city grid. I think distance from city center?

5000th St.
Savonburg, KS

Also not in a city.
Or consecutively-numbered.

Depends on how big the city is.

There are a lot of streets, especially in England, called “High Street”. But none called “Higher” or “Highest”.

Manhattan, NY, NY goes up to 220th in consecutively numbered streets.

Somewhere in San Francisco where there is a lot of outdoor dope smoking and drug taking, would wualigy as the highest street in the world.

I found a 500th street in Rake, Iowa

Infinity Court
Carmichael, California.

Please clarify the question.
Highest in elevation?
Highest in numbering sequence?
Highest in feeling High?

@Forever_Free Highest in numbering sequence?

@Forever_Free @all Also include negative numbers. If real?
