My dissertation concerns Prehispanic causeways, or raised roads, in the Maya area. I have also spent a considerable amount of time on roads throughout the world and by coincidence there are plenty of songs about roads or being on the road. These can be categorized in a similar way as ancient causeways.
There are roads leading to mythological, metaphorical, and symbolical places. Some of these roads are well known like AC/DC’s Highway to hell:
and Chris Rea’s The road to hell:
Another category of roads describes the points they do not connect, like Ozzy’s Road to nowhere:
We also have songs about real physical road systems, like Frank Zappa’s Inca roads (thanks to Michael Smith mentioning this song):
The time of the day when a road is used is also of importance in understanding communication, categories of people using the roads, etc. Some roads are only used during the dark hours, like the Midnight highway by Accept:
Finally, I end this with the users of roads: Journey man by Iron Maiden:
and a rover, wanderer, nomad, vagabond, call me what you will…Wherever I may roam by Metallica where the road even becomes a bride:
