Quick tests
Meaning / construction test
Are you simply describing the principal road rather than invoking a regional or official road class?
If yes: Use “main road.”
If no: Use “highway” where that is the established regional or official term.
Caveat: Road classifications vary by jurisdiction; do not treat “highway” as a universal one-to-one synonym for every “main road.”

The phrase describes the locally important route without naming a formal road class.
We took the highway north.
The regional road term is intended.
Traffic was heavier on the main road through town.
