The mountain accommodating the new metro

Stockholmsgranit är grå eller rödaktig och är bra berg för tunnlar. Så här ser den ut under Londonviadukten. Vid kartering dokumenteras bland annat hur mycket sprickor det finns i berget. Ett valvformigt tak ger stabilare tunnel.

Preferably Stockholm granite but never episyenite. That is what the geologists want. Join us as we go down amongst the gneiss, fissure systems, and mountain cracks.

Geologists are carefully studying the rock dawning as the tunnels are blasted into being. Their tunnel mappings are important for how the work will proceed.

Förbifartens och nya tunnelbanans tunnlar korsar varandra med fem meters marginal väster om Akalla.

Just west of Akalla, two of Stockholm’s major infrastructure projects cross paths with each other. The new metro to Barkarby will be blasted into being five meters under the tunnels for the E4 Bypass Stockholm.

The need to adapt to other underground or built-in facilities is common when building in Stockholm. Good dialogue and early cooperation are therefore important.

Sweden’s longest escalator, latches, tiles, tracks and power lines shall be ordered. Although it will be several years before all tunnels are even completed, the planning work is already in full swing.

A milestone has been passed in the work of extending the Stockholm Metro. The first blast in Södermalm marks the start for the extension straight under the water in the Saltsjön bay.

Around 80 guests, seven speeches and one big bang. On Monday March 4th, the historic expansion of the Metro was initiated.

Construction began with a ceremonial starting blast in a rock cavern in Barkarby, which brought together all the parties who are involved in paying for the new Metro.

The Metro to Barkarby will be completed in 2026. These pictures show what the entrances to Barkarbystaden will look like in the future.

This station on the Blue line will have two entrance ways into the emerging city centre. The eastern entrance way will be situated on the ground floor in a new building, while the western entrance way will be constructed as a pavilion in the middle of the central square.

These images portray a future scenario that may be changed.

Both ships/barges and trucks are still of interest for the transportation of rock from the Metro construction sites. This is apparent from analysis of the load tests conducted at Blasieholmen.

Now when the Metro is to be extended southwards from the station in Kungsträdgården, the same construction tunnel will be used as that used in the 1970's. The tunnel contains fill from the last time the Metro was extended.

Planeringen av nya linjen Fridhemsplan-Älvsjö påbörjas 2020

Work on the next step to expand the Stockholm underground system – the line between Fridhemsplan and Älvsjö – will start soon, according to a decision by the City of Stockholm and Region Stockholm.

“Early next year we’ll start getting organised to work on the new project”, says Stefan Persson, Head of the Planning Department for Region Stockholm’s Extended Metro Administration.

What affects the environment least – transporting rock by boat or by truck? In October this will be tested on Blasieholmen, in the very centre of Stockholm.

On Blasieholmen, a work tunnel still remains from when the Kungsträdgården underground station was constructed in the late 1970's. The tunnel is currently full of rubble, but because the tunnel will be used again when the Blue Line is extended south, this needs to be removed.

Preparatory works are currently under way at Kungsträdgården Station, where the Blue line will in time be extended in the direction of Nacka and Söderort.

Up until now the tracks at Kungsträdgården have ended a hundred metres or so into the tunnel south of the platform. At this point the entire platform structure will be demolished before work can start on construction of the new tunnels to extend the Blue line southwards.
