City of Stockholm and region Stockhom; Metro expansion management (FUT) works together to reduce the number of transports through Stockholm's inner city. This is done by transporting blasted rock from the tunnel between Kungsträdgården and Hammarby canal. The mountain goes with a barge 1-2 times daily

The transport takes place to Loudden opposite quay 3. One transport saves approx. 80 transports by heavy truck through the city. A total of approx. 600,000 tonnes will initially be transported by barge until 2024.

Responsible for transport between Blaiseholmen and Loudden is contractor OHLA on behalf of FUT
