Year 2021

The TUB A project is a yellow line in the public transport system in Stockholm, which includes three new metro stations Hagastaden – Södra Hagalund – Arenastaden and new metro tunnels between them. Two underground metro lines of about 4.0 km in length are being designed, which are about 30 m deep underground. A parallel service tunnel and three working tunnels (HGSw.t. HGL w.t. and ARS w.t) have been designed to serve this metro line, which will assist in the construction and execution of works in both the service tunnel and the metro. During the installation of this project, about 670,000 cubic meters of rock will be blasted and about 37,000 cubic meters of concrete will be used. The project is planned to be implemented in 8 years.
