The expressways that link a country’s cities are its nerve paths. As loads increase, safety is a major issue, especially on bridges. The A9 in southern France is one of the most heavily used highways in the country. After a five-year construction period, the modernized and upgraded section between Montpellier and Spain opened six months early, thanks partly to Sika’s expertise and technologies.
One of the challenges encountered while modernizing and upgrading the highway was strengthening the bridge piers in poorly accessible terrain.
The reinforcement work had to take place with the highway open to traffic. Sika provided training for applicators and supported the project with technical advice.
