Massive infrastructure projects in Stockholm

Published June 2015 in collaboration between Invest Stockholm and The Swedish Wire.

One of Europe’s largest infrastructure projects, The Stockholm bypass, is currently under development in Stockholm. It's a huge undertaking with opportunities for international companies to get involved.                                                                                          

The Stockholm bypass – or Förbifart Stockholm – is a new route for the European highway (E4) past the Swedish capital. With a budgeted construction cost of 3.1 billion euros, the link will be one of the longest road tunnels in the world.The aim is to relieve arterial roads and the inner city of traffic and reduce the vulnerability of the city’s traffic system. Just over 18 km of the total of 21 km of the link are in tunnels.

Johan Brantmark, the director of the project at the Swedish Transport Administration (Trafikverket), said that the land acquisition plan and environmental permits have been approved by the government, and that the actual construction work is planned to start in the spring of 2016.

“The preparatory works have started and the amount of field work being performed is continually increasing," he said.

The project also opens up opportunities for international contractors and construction companies.

Johan Brantmark explained that foreign firms are invited to tender for the opportunities to provide the tunnels and civil works, which are expected to cost 2 billion euros over the next two years.

“The Swedish market is not enough, so we need to turn to the international market as well," he said.

Olof Zetterberg, chief executive officer of Stockholm Business Region, also said that the Stockholm bypass offers opportunities for foreign companies. There are altogether 17 tenders in the project, he said.

“In our dialogue with Swedish Transport Administration, we are in contact with suppliers from France, Germany, Spain and other markets around the world”, Zetterberg said.

“In our view this proves that the Stockholm bypass project has the potential to attract further foreign suppliers. We believe that the attraction focus also will provide increased interest for other projects in the region”.

The Stockholm bypass is not the only big infrastructure project in the Swedish capital. Indeed, in recent years Stockholm has been undergoing a transportation revolution, Brantmark said.

The investment potential for the Stockholm region has increased by 16 billion Euro in the year that has passed and now amounts to more than 100 billion Euro until 2021. Beside the Stockholm bypass, two major drivers are 180,000 new housing units until 2030 and extension of the subway.

The inner ring road around the city of Stockholm is almost complete. In the north, Norra länken, is almost finished, while in the southern part of the city, Södra länken was completed in 2004, Brantmark explained. There are also plans to start the final piece in the east of the city - called Östlig förbindelse. Yet another project is The City Line, a 6 km-long commuter train tunnel beneath central Stockholm. 

Here Stockholm Business Region lists the three largest infrastructure projects:

The East Link (Ostlänken)
The East Link is planned as a new double-track high-speed railway in the eastern part of Central Sweden. It will be part of a possible future high-speed railway running between Sweden’s metropolitan centers and the Scandinavian capital regions. Construction is planned to start next year. 

The Mälaren Line (Mälarbanan)
The Mälaren Line Project will expand the railway between Tomteboda and Kallhäll, northwest of Stockholm, from two tracks to four.
The project has a total value of SEK 13.9 billion (€1.5b) and is organized in three phases starting/started in 2012, 2016 and 2025.

Expanded Subway in Stockholm
Ten new stations will be built in Stockholm's subway system. The total investment volume is 3 billion euro. Planned construction period is 2016-2025.
