Question

What are 6 Lane Highways and Why are they used?

Answer 1

#1
There is a highway with 3 lanes northbound and 3 lanes southbound. You call it:

A. A 3-lane highway.
B. A 6-lane highway.


Maybe it's obvious if you say 3-lane highway because your options are either 3 in each direction or 2/1. A 2-lane highway is more ambiguous however. Is it 1 each direction or 2.
