I've heard it called both. If you ask the locals in Portreath it's the Portreath Tramroad. Similarly, if you ask anyone in the Poldice, Todpool, Twelveheads area, they lean toward Poldice.
I take partial responsibility for this entry as I noticed there were no less than 4 entries in the DB all labeled Portreath, and non of them specific. Non specific entries such as this clutter the database and lead to confusion.
After a quick fiddle we can now see what's what; this can all be easily altered if there are any preferences or differences of opinion. 🙂
