Until July 29, at Saint-Chamond, work continues on the Langonand viaduct.
Every night from 8:30 p.m. to 6:00 a.m., traffic in the Lyon / Saint-Etienne direction is switched to the left lane in the Saint-Etienne / Lyon direction. Circulation will therefore occur in two directions at this level. The left lane will be neutralized in the Saint-Etienne / Lyon direction.
In addition, the exit ramp n ° 16 “Saint-Chamond la Varizelle” remains closed in the direction Lyon / Saint-Etienne throughout the duration of the work.
