Travaux de remplacement des appareils de dilatation du pont Laurent Bonnevay

SYTRAL Mobilités commissioned the replacement of expansion joints on the Laurent Bonnevay bridge over the Lyon Metro Line A, which had deteriorated since the line's opening in 1978. The original expansion devices had become severely cracked and weakened from repeated train passages and vibration impacts, making replacement necessary despite periodic maintenance reinforcement. COLAS RAIL was awarded the contract on 24 April 2026 for €74,188.30 to complete this work.
