: What is the origin and meaning of the phrase: It will cost you tuppence to cross a penny bridge?

Where did you find this? I Googled a bunch of combinations of those words and came up empty. I did however come across references to Ha'penny Bridge in Dublin - it seems it is so-called because it cost a ha'penny to cross it at one time. "Tuppence to cross Ha'penny Bridge" might be a clever remark about inflation (or something like that).
Is it a coincidence that you signed your post Aitch? a penny / ha'penny?
