Upgrading of the motorway network

Upgrading of the motorway network
Context & Issues

Artelia continued providing services to concession companies managing the French motorway network. Highlights of the year 2016 included works to widen the Boulou-Le Perthuis section of the A9 and make it more earthquake-resistant on behalf of ASF. 

Widening works on the Rampe des volcans on the A71 began in September 2016 on behalf of APRR. The works on the A13 between Pont l’Evêque and Dozulé also began for Sanef/Sapn, which has also commissioned Artelia to restructure interchange no. 31 between the A16 motorway and the Rn42 trunk road in Saint-Martin-Boulogne
