ISC received IABSE Structural Award 2018 for the TP 30 Railway bridge on April 25th 2018.

The bridge which is a part of the Copenhagen – Ringsted railway at Vallensbæk – was designed by ISC Consulting Engineers A/S The bridge is 512 m long and was part of a design & build contract handed over to a consortium comprising CG Jensen A/S and Barslund A/S with ISC Consulting Engineers A/S as consultants.

The superstructure is a composite box girder, resting on beams and a total of 7 cross beams with a span up to 36 meters across the motor road. It is the first time a composite structure has been used in Denmark for a high speed railway.

The concept and building method were chosen as it would give the least disturbance of the traffic on the motor road which is one of the main roads to Copenhagen. The mounting of the bridge superstructure only required shut down of the motor road during two weekends.

The railway crosses the motor road in a very sharp angle off 15.8across the northbound lanes and 21.8across the southbound lanes. The concept has been carefully aligned with the environment to minimize the visual barrier effect.

The railroad is designed for high-speed trains going up to 250 km/h, and a special focus has been set on the structure’s dynamic behaviour.
