Cartsdyke Roundabout lies on the A8 between Greenock and Port Glasgow on the south bank of the Clyde. It is at the heart of the old docks, which survive to either side, although the land immediately neighbouring the roundabout has been redeveloped. The A8 always turned a corner here, and the roundabout is primarily there to ease the bend since it was widened to be a dual carriageway and also provide access to the developments on the shore side. The old curve of the A8 can be assumed to follow the pavement that still runs on the inside of the roundabout.
The roundabout is a fairly simple 4 arm roundabout, the A8 turning from the east to south west. The other two arms are unclassified, Cartsdyke Avenue heading west to a small office development and James Watt Way runs north to a Hotel, restaraunts and flats in converted warehouses originally built for the docks.
