Tay, Firth of (Scotland)

The Firth of Tay (; Scottish Gaelic: Linne Tatha) is a firth on the east coast of Scotland, into which empties the River Tay (Scotland's largest river in terms of flow). The firth is surrounded by four council areas: Fife, Perth and Kinross, Dundee City, and Angus. Its maximum width (at Invergowrie) is 3 mi (4.8 km). Two bridges span the firth: the Tay Road Bridge and the Tay Rail Bridge. The marshy Mugdrum Island is the only major island in the firth. The Firth of Tay in Antarctica was discovered in 1892–1893 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.
