Seamless integration of Corkelast ERS in new ‘Hisings Bridge’, Gothenburg

edilon)(sedra has been contracted to supply and install more than 2 km of Corkelast® ERS (Embedded Rail System) as part of the tram line on the newly built ‘Hisings Bridge’ in Gothenburg, Sweden.

The bridge, which is currently under construction, will replace the existing ‘Göta älv Bridge’ which is in a poor condition and needs to be replaced to avoid high maintenance costs. The bridge connects central Gothenburg with Hisingen city and includes a vertical-lift section.

The first meetings between Gothenburg City (Traffikkontoret), COWI (the lead-engineers) and edilon)(sedra took place in 2012. From the very beginning our ERS has been one of the preferred system solutions and in February 2020 our company was officially awarded the contract.

Cost effective designs

One of the arguments in favour of ERS is its limited installation height as the rail system is completely incorporated in the bridge superstructure. The system thereby saves space and promotes cost effective designs. Additional benefits include its excellent vibration isolation characteristics and positive experiences in the past: ERS is already in use in more than 10 km of rail track in Gothenburg!
