Fife is a peninsula in eastern Scotland bordered on the north by the Firth of Tay, on the east by the North Sea and by the Firth of Forth to the south. The route to the west is partially blocked by the mass of the Ochil Hills. Almost all road traffic into and out of Fife has to pass over one of four bridges, south on the Forth Road Bridge (public transport and cyclists only) and Queensferry Crossing, west on the Kincardine Bridge or north-east via the Tay Road Bridge, the exception being traffic headed north on the M90.
