A991 road

The A991 previously formed a complete dual-carriageway circle of the city centre. However, the southern section of the ringroad, where it is named South Marketgait, has undergone major reconstruction as part of the city's waterfront redevelopment scheme. Previously, the A991 met the A85 at the Riverside roundabout, beside Dundee Railway Station; and just to the east, the A92 at a grade-separated junction at the northern terminus of the Tay Road Bridge. As of 2015, this has been replaced by a grid scheme of streets, with the east and westbound carriageways of the A991 now separate streets. Major realignment has also taken place of the on- and off-ramps of the Tay Bridge. Travelling west on the A991 from East Dock Street to West Marketgait now requires driving three sides of a rectangle, passing below the northmost span of the Tay Road Bridge.

The rest of the A991 is still dual-carriageway. Travelling clockwise from the railway station, the A991 is known as West Marketgait between there and the West Port Roundabout. Past the West Port Roundabout, in the section known as Marketgait, the road goes North to the Dudhope Roundabout, the southeast terminus of the A923, then east to the Ladywell Roundabout after which it goes through a tunnel under the A929 (Victoria Road) and curves southeast to the East Port Roundabout. South from here, East Marketgait meets South Marketgait at the signal-controlled East Dock Street junction. The A991 then multiplexes with the A92 back to the Tay Road Bridge northern terminus.
