A77 autoroute

The A77 autoroute is a motorway in central France. The road starts at the hamlet of Rosiers in Seine-et-Marne and finishes to the south of Nevers in Nièvre. It is also known as the l'Arbre - the motorway of the Tree.

It has been designed to minimise its effect on the environment. Each of the rest areas bears the name of a species. The road has been integrated into the landscape helped by zoologists to allow the passage of the animals (wild or cattle) from one side of the road to the other, as in the forest of Montargis. This added to the cost of construction.

The motorway is managed by the company the Paris-Rhine-Rhone (SAPRR). It is a toll road with 2x2 lanes and totals 96 km.

The motorway is managed by the département of Nièvre. It is a free motorway with 2x2 lanes.

Plans are to extend the motorway to Moulins, with sections already under construction on the existing RN7. The by-pass of Moulins and Villeneuve-sur-Allier has already been completed to autoroute standard. The remaining upgrade is expected to be completed in 2009.
