Much of the railway infrastructure in Sweden’s capital was built in the 1950s and needs renovating over the next few years. The section in Stockholm Getingmidjan acts as the gateway for all trains coming in from the south of the country, making it one of the busiest railway lines in Sweden. The contract is worth approximately US$100 million and includes upgrading and replacinig five railway bridges and two pedestrian bridges. In addition, both the 120m-long Riddarholmen tunnel, and the approximately 600m-long Söderström tunnel will be refurbished to bring them up to the latest technical standards.
This infrastructure project is made even more challenging by the city centre location. Disruption to public and private transport must be kept to a minimum, so Implenia will be making considerable use of the available sea transport options to bring in and take away materials. Construction is scheduled to begin in summer 2017 and will take about four years.
