Replacement of a 120 years old bridge with a new structure
The existing stone arch was in bad condition after over 155 years of service so it has been decided the structure would be replaced by a new arch structure. The ABM precast arch was chosen as the best system in terms of durability (simply reinforced concrete) and speed of construction, which is critical item on any rail works. ABM installed the structure incl wingwalls in just 16 hours.
The new structure is so called green bridge connecting the Alp and the Carpathians Mountains allowing the wild animals to migrate. The structure was constructed over a live motorway with minimum disruption to the heavy motorway traffic. The installation has been done by halves. The first halve in 10 days and the second in just 8 days which is total 18 days for 112,5m long structure.
