Spanning 255 m, the Zandhazen railway bridge is the longest railway arch bridge in Europe. It carries two railway tracks over the A1 motorway in Muiderberg, east of Amsterdam, and has a width of about 17 m and height of 55 m. The bridge was opened in August 2016.
Due to the need to minimise disruption to road and railway traffic, the most critical aspect of the design was to ensure ease of transportation and installation. For this reason, steel grade S460 was chosen for the main girders and arch sections to limit the bridge self-weight.
The total cost of the railway bridge, including the substructure, was about € 40 Million.

STIGA Sports Arena Eskilstuna, Sweden
STIGA Sports Arena complex is located in the Munktellstad district of Eskilstuna, about 110 km west of Stockholm, and was opened in 2017. The arena complex is used for sporting events, concerts, large conventions and fairs. The main arena comprises 3,700 seats for sporting events and approximately 5,000 seats for concerts. In total it has three individual sports halls.
Steel is, by some margin, the most commonly used material to construct indoor arenas due to its engineering, aesthetic, economic and environmental attributes. In the STIGA Sports arena, long span steel roof trusses provide the large open plan areas required for unimpeded spectator viewing.
The selective use of high strength steels for the elements in the trusses that are not governed by instabilities led to a significantly lighter structural solution than that using conventional strength steel.
