This new structure is a part of the SAA project, a large infrastructural project that aims to increase the road capacity of the Schiphol-Amsterdam-Almere corridor, to alleviate the current traffic congestion and improve the environmental quality of the area. The superstructure comprises a steel arch bridge with a diagonal hanger configuration. With the span length of 255 m, the bridge is considered to be the largest railway arch bridge in Europe. Due to the required necessity to minimise the hindrance of the road and railway traffic, the erection of the bridge has proven to be the most challenging aspect during the design process. Steel grade S460 is chosen because of limitations of the bridge weight during transport and installation. SCIA Engineer was used in all design phases of this steel and concrete railway bridge for linear and non-linear static calculations. An important aspect of the bridge is the construction method, because this has a large impact on the forces and deformations of the bridge. With the use of the Construction Stages module in SCIA Engineer all erection stages were analysed and the bridge has been completed with success.
