Dornoch Firth National Scenic Area is a haven on the east shore of Highland, Scotland . It makes part of the border between Sutherland and Ross and Cromarty. The firth is assigned as a Special Protection Area for worldlife conservation goals in conjunctively with Loch Fleet. Supplementary, alongside with Morrich More , it owns the label of Special Area of Conservation. On 16 August 1809 the firth was the background of the Meikle Ferry catastrophe when an over-fulled ferryboat dived with the casualty of 99 people. In 1991, a bridge showed up, the fresh Dornoch Forth Bridge giving a briefer path on the A9 road between Inverness and Thurso. Before the bridge was designed, the traffic had to pass by route of Bonar Bridge .
