Citybanan is a 6 km long commuter train tunnel that will run beneath the entire inner city. Citybanan will increase rail network capacity in the Stockholm region and throughout Sweden while reducing the risk of disruption. At present, only two tracks traverse central Stockholm. These are already fully utilized, and the Swedish Rail Administration is forced to turn down requests for additional rail traffic.

With Citybanan in place, it will be possible to expand the rail network throughout the region, making commuting easier across an even wider area than at present.

The E18 is Stockholm’s western arterial approach road. With 16 at-grade intersections and heavy traffic, the motorway suffers from high accident rates and frequent traffic jams. Residents along the road also suffer from high noise levels.

Reconstruction of the 8 km Hjulsta–Kista section will reduce traffic noise. Grade-separated intersections, segregated local traffic and improvements for through traffic will also improve traffic flow and road safety. Some parts of the route will be covered, and housing will be built on top of the covered road in Tensta and Rinkeby.

2009–15

The Stockholm Bypass is a new road, built to motorway standard, linking the northern and southern parts of the county. The route will relieve Essingeleden, the motorway on Stockholm’s western flank, allowing more car journeys to be made between the different parts of the county. This will enable more people to take advantage of employment opportunities, as well as reducing the risk of traffic disruption.

The bypass route runs from Skärholmen to Häggvik, with interchanges at locations including Lovön, Bergslagsplan and Hjulsta. The route as currently planned is 21 km long, 17 km of which will go through a tunnel. New urban centres with housing, workspaces and other amenities are planned in areas such as Barkarby–Jakobsberg and Kista–Sollentuna–Häggvik.

Construction period:
2012–22

Odenplan is currently one of the inner city’s largest service and transit hubs. The construction of Citybanan, the new underground rail line beneath central Stockholm, and a new metro line to Hagastaden will streangthen this role.

A new branch of the green metro line is planned to serve the Hagastaden development. This new neighbourhood is expected to generate a more than twofold increase in the number of people travelling to and from Odenplan.

Construction period:
2013–16

2011–14

The Mälarbanan line is being built to increase capacity and reduce journey times for commuter and regional train services. Roughly three million people live and work in the Stockholm–Mälaren region, and regional and commuter rail traffic has increased significantly in the past decade. To allow continued traffic increases on the Stockholm–Västerås–Örebro corridor, new tracks are needed between Tomteboda and Kallhäll.

Construction period:
2011–15

Norra länken (the Northern Link) is an all-new road running from Norrtull, in the north of the inner city, to Värtahamnen, connecting to Roslagsvägen at Stockholm University. The road will be mainly in tunnel and forms part of a coherent orbital road system along with Essingeleden and Södra länken.

The road will provide increased capacity to serve Värtahamnen and Frihamnen, Sweden’s principal harbours for cargo and passenger traffic with the Baltic states, Finland and Russia. It will also boost the new residential developments planned in Hjorthagen–Värtan–Frihamnen–Loudden and Norra Djurgårdsstaden.

Construction period:
2006–15

As new residential areas develop in central Stockholm, public transit needs to be expanded. Spårväg City, a downtown LRT line, will create a brand new east–west transit route through the city centre. Modern, high-frequency LRT will provide an attractive transit option that may attract commuters who would otherwise drive, and will therefore have a positive environmental impact. The new LRT route will also replace some current inner-city bus routes. The proposed route serves T-Centralen, Stockholm Central Station and Fridhemsplan, all of which are important transit hubs.

Construction period:
2010/11–13

The Tvärbanan LRT line currently runs from Hammarby Sjöstad, southeast of the inner city, to Alvik, west of Stockholm. The line carries over 40,000 passengers daily. Tvärbana Norr is an extension of the present line north from Alvik, with two branches serving Solna and Kista respectively. Tvärbana Norr will bring major improvements to cross-city connections by joining up the lines running into central Stockholm. Once the extension is complete and the number of homes and workspaces grows, ridership will increase to more than 150,000 passengers each weekday.

Construction period:
2009–17

An eastern extension of the existing Tvärbanan LRT line will facilitate fast journeys between Hammarby Sjöstad, southeast of the inner city, and Slussen, the principal inner-city transit hub. At the same time, the LRT system can be integrated with a modernized Saltsjöbanan commuter train line. A new transit hub will be created at Danvikstorg station. The associated Danvikslösen project will create a city-style environment linking three of the fastest-growing developments in the Stockholm region: Hammarby Sjöstad, Henriksdal–Kvarnholmen and Sickla. Within a decade, this area will be home to 50,000 people and 20,000 workspaces.
