From November 15 to 17 and from November 22 to 24, 2024AREA is undertaking road renovation work in the Dullin tunnel, located on the A43 motorway between Lyon and Chambéry. This project, aimed at improving the safety and comfort of users, involves traffic modifications, with a change of lanes every Friday from 10 p.m. until Sunday at 12 p.m.
During the work, traffic in the Dullin tunnel will be maintained thanks to a switch of the tracksallowing vehicles to circulate permanently without resorting to external diversions. Drivers will travel in one lane per direction in a single tube, instead of the usual two lanes.
AREA advises users to find out about traffic conditions, particularly during rush hours, via Autoroute INFO on 107.7 FM or the mobile application.
Renovation of the roadway, unchanged since 1974will integrate coatings containing up to 40% recycled materials and 22% white aggregates. These additions will improve visibility for motorists and reduce energy consumption in the tunnel, providing savings of 40-50% on lighting.
Key figures:
• Renovated surface : 30,000 m² (more than 4 football fields)
• Staff mobilized : around 70 people
• Cost of work : 900 000 € HT
To follow the progress of the site, the work schedule is available on voyage.aprr.fr/travaux-et-operations
