The motorway, 170 km long, cost a total of € 650 million. It is dual-carriageway both ways on its entire course and service areas are positioned at regular intervals. It is toll free.
The motorway was built with a special road surface to allow rain water to run off quickly, but it is ineffective with snow that often falls in large quantities in winter, so snowploughs are employed regularly. Motorway traffic radio 107.7 broadcasts A84 information specifically.
The highway is free throughout its entire length. The various governments have studied the concession of this highway, but the regional authorities of Brittany and Normandy have convinced the public authorities to build and manage this highway with public funds.

The A84 is interrupted at Avranches. The bypass to the west of Avranches, by the RN 175 with two double lanes, has geometrical characteristics which do not allow the construction of motorway characteristics and status. An East motorway bypass for the A84 was therefore planned in the long term. The State bought 60 hectares of land and destroyed four houses along the route. However, the works are yet be launched. The land is still owned by the state.
The A84 is also to be extended to Nantes by upgrading the RN 137 dual-carriageway, thus creating a Caen-Rennes-Nantes route. This was abandoned, along with other projects of dual-carriageway upgrades in Brittany (RN 157 and RN 12 were planned to become A81 and RN 165 was planned to become A82).[1]
In addition at Rennes, the construction of a "south-east bypass" will make it possible to avoid the Rennes ring-road on this route. Construction was due to commence from 2021 but was abandoned.
