The well-known Transarc people-mover that links Arc 1800 and Col de la Chal at 2600 m is currently being upgraded at Les Arcs, increasing the comfort and capacity on the route as well as the speed of the trip.
The current Leitner-built Transarc lift opened in 1991 with 15 person cabins travelling at 5 metres per second.
The new lift will have 10 person cabins but ascend much faster, at 7 metres per second.
It means capacity on the route will increase by nearly a quarter from 3,000 to 3,700 people per hour and the nearly 3.5km lift will be faster, 9 minutes instead of the 13 minutes of the old lift.
The new lift will also use about 10% less energy and have 600m of photovoltaic panels integrated into the structure of the lift stations to generate green power.
Work has already taken place in Arc 1800 at the Transarc's base with new escalators and a lift making it easier to access the base.
