What is the common road width?

Question

What is the normal road width? Single lane, double lane and triple lane. Is there a different in width in Asia, Africa, Europe and America? Please Advice.

Answer 1

According to FHWA, 12 feet per lane is the standard width for highways(or Freeways), although it common to see lanes as small as 11 feet.

On residential roads, I have seen it as wide as 14 feet total!

In most of Asia and Europe, lanes are 3.3 Meters wide.

Standards vary from Country to Country.

Answer 2

some states here in America have smaller streets than the other state. Where I live in NJ, each lane is really wide, probably 10 feet. In NY, even on the highway, the lanes are probably 9 to 9.5 feet wide. But they are smaller.

Not sure about other countries, but I'm guessing the same thing. Check google.

Answer 3

12 feet per lane is the default standard.......
