A90 road

The A90 road is a major north to south highway in eastern Scotland, running from Edinburgh to Fraserburgh, through Dundee and Aberdeen. Along with the A9 and the A82 it is one of the three major north–south trunk roads connecting the Central Belt to the North.

The creation and development of the A90 road has to be understood in terms of the development of the economy of the North-East of Scotland which had resulted in an increase in traffic along the route between Perth and Aberdeen. In recognition of this, in 1979, the British government announced that it was giving priority to the upgrading of the route to dual carriageway standard. It had already been decided that the trunk route between Dundee and Stonehaven which, previously, had followed the same route as the railway line between the two towns, would now follow an inland route through Forfar and Laurencekirk. The new route would incorporate the A85 from Perth to Dundee the A929 between Dundee and Forfar, the A94 between Forfar and Stonehaven, and the A92 from Stonehaven to Aberdeen; in 1994, the confusion of numbers was resolved with the renumbering of these roads and the creation of the A90 Edinburgh to Aberdeen trunk road. The coastal route from Dundee to Stonehaven was detrunked in 1978, at the same time as the inland route was trunked.
