After 35 years, Bernar Venet will realise his vision of Arc Majeur, a monumental sculpture that appears to span across a busy highway. The inauguration of the 250-tonne steel sculpture, which will be the largest public artwork in Europe, will take place on 23 October. Originally conceived for a site in France in 1984, the work has found its home in Belgium.

Arc Majeur takes the form of a sweeping, circular arch springing from the earth on either side of a highway linking Brussels to Luxembourg. The massive steel pieces have been installed on opposite sides of the road. They measure just over 90 feet in height on one side of the road and nearly 200 feet on the other. The steel semi-circle gives drivers the sense that they are driving right through the artwork.
