A steel arch bridge has been installed across the Thomassentunnel and the A15 and N15 motorways in the Netherlands, forming a key link in the port of Rotterdam’s proposed Theemswegtracé railway line.

Slated for completion in 2021, the Theemswegtracé railway line will measure approximately 4 km long and will run from Merseyweg, over a raised railway viaduct along Theemsweg, all the way up to Moezelweg via Neckarweg.

The first bridge structure of the EUR300 million (USD335.3 million) project – spanning Rozenburgsesluis – was installed during April. The second bridge, which comprised a 4,100-tonne steel structure, measured 269 m long, 13.7 m wide and 28 m tall; Krimpen aan den IJssel-based Hollandia built the bridge structure.

A consortium of BESIX, Dura Vermeer, Mobilis, Hollandia and Iemants is constructing the substructure of the Theemsweg route, which, in addition to the steel arched bridges, includes a concrete viaduct. All works have been commissioned by the Port of Rotterdam Authority in order to overcome bottlenecks around the Calandbrug Bridge area as this structure reaches the end of its technical lifespan.

This steel vertical-lift bridge for rail and road traffic in the port of Rotterdam area is the connecting link in the Betuwe route to the European hinterland. For ocean shipping, the vertical-lift bridge forms the gateway to the Brittanniëhaven.
