Highways in Ecuador

The highway designations begin with the letter E followed by a number on a shield that looks like the ones of the USA interstate highways.

If the highway is a trunk highway (travelling north to south), the number is odd.

They are numbered from smallest to largest from the west to the east.

If the highway is a transverse highway (travelling east to west), the number is even.

They are numbered from smallest to largest from the north to the south.
