Two bridges span the firth, the Tay Road Bridge and the Tay Rail Bridge.

The Firth of Tay in Antarctica was discovered in 1892-93 by Captain Thomas Robertson of the Dundee whaling expedition and named by him after the one in Scotland. He also named nearby Dundee Island in honour of the main city on the firth.
