Aerial tramway of the Plateau de Bure, Cable transport system in French Alps, France.

The aerial tramway of the Plateau de Bure is a private cable transport system in the commune of Le Dévoluy, linking l'Enclus at 1,400 m to the IRAM observatory on the plateau at 2,600 m. Its 4,040 m make it France's longest to-and-fro tramway. Two dark grey steel lattice towers with crossarms and a ladder carry the cables; the cabins run on two carrying cables and one hauling cable.

The first tramway was built in 1980 by Pomagalski for the Institut national d'astronomie et de géophysique. On 1 July 1999 a cabin fell 80 metres after its haul rope broke, killing twenty passengers; the cart brake had been removed in 1986 without the manufacturer's consent. A replacement by Leitner Ropeways entered service in late July 2015 and was inaugurated on 2 October 2015.

The tramway serves the researchers of the observatory and is not a tourist transport. Those who ride it are generally part of a scientific team, which gives the plateau the feel of a remote working station rather than a public destination.

Access to the tramway is not open to the general public and requires prior authorization, as the system operates mainly for scientific purposes. Weather on the plateau can change rapidly, so warm and windproof clothing is a practical necessity.

Some of the antenna components used at the observatory were brought up piece by piece in the tramway's cabins, as no other route could handle equipment of that size and weight. The cabins were specifically designed to accommodate oversized scientific loads.
