BRUSSELS, July 29 — The 200-tonne steel sculpture, entitled "Arc Majeur”, will be revealed next October at an as-yet unknown date.

"Arc Majeur” will be on view on either side of the E411 motorway near the town of Lavaux-Sainte Anne in Belgium.

The colossal piece, created by French artist Bernar Venet, is composed of two sweeping arcs that measure 60 and 20 metres respectively.

The large arc, made of three sections measuring 20m each, will be set up on one side of the motorway, while the smaller one will be installed on the other side.

The arcs were built in workshops owned by the John Cockerill Group, whose philanthropic arm funded the project, in the Belgian town of Seraing.

The colossal steel sculpture was designed so as to give people driving on the highway the impression of driving through the arc.

"Arc Majeur” was initially commissioned by former French culture minister Jack Lang in 1984.

The sculpture was supposed to be installed along the A6 motorway near the French town of Auxerre, but the project was abandoned in the face of strong local opposition.

French artist Bernar Venet rose to fame in the late 1960s with his seminal 1963 installation "Tas de Charbon” (Pile of Coal).

He started to incorporate arcs and angles in his compositions in the 1970s, ultimately experimenting with three-dimensionality through dynamic steel sculptures.

His artworks are usually named after their mathematical compositions, referencing the degree of the angle or curve that determines the sculpture’s form. — AFP-Relaxnews
