Highway A10 Bos & Lommer viaduct,

The Netherlands


In assignment of the Municipality Engineering unit, FDN was responsible for the engineering of the viaduct over the A10 highway in Amsterdam. The design concerned a new viaduct between two existing viaducts over the highway A10. The building time and phases were crucial as the highway could not be closed for long periods due to heavy traffic.
