Calder Junction is the junction of the A71 and the A720, the Edinburgh City Bypass. It forms a large, signalized roundabout, with the D2 A720 passing beneath. Its north-facing slips were extended and woven into Hermiston Junction when that was built.
It most obviously provides a connection between the bypass and the A71, a radial route linking Edinburgh to Heriot Watt university and a park and ride just to the west, then southern Livingston, West Calder, and beyond. However, it also provides access between the M8 and the A71, with a slip from the roundabout immediately branching off to join the M8, and traffic leaving the M8 at the Hermiston Roundabout climbing up here to join the A71 citybound, making it the easiest route from the M8 into Edinburgh.
Before the bypass existed, the A71 ran straight across, forming T junctions with Cultins Road (in what is now Bankhead/Sighthill) and Gogar Station Road (in Hermiston village). The roundabout stands in a right angle in the Union Canal, which crosses the A720 via an aqueduct to the north and goes underneath the A71 to the east.
