A46 MOTORWAY – WIDENING BETWEEN ANSE AND GENAY

Catering for increasingly heavy traffic

Traffic volumes on the A46 have been rising from year to year. This motorway currently carries nearly 45,000 vehicles a day. That figure is expected to increase by another 10,000 by 2020. On that basis, the aim of this highway widening work was to boost the motorway capacity, so as to enhance traffic flows and safety.
 
Work to widen the motorway to three lanes per carriageway, which was completed on 14 November 2014, has helped to improve traffic conditions.
This work was carried out on a 6-km stretch between the Neuville-Trévoux junction (No. 2) and the future A466 junction at Ambérieux-d’Azergues. The connection between the A46 and the A6 in the Paris direction was also improved as part of the plan to make the A46 Nord safer.
