Road construction was to take place simultaneously with railroad construction. Highway 50 (today E6) traversing Saltfjellet was opened in 1937, but it was a low-quality road. From Rognan to Langset, a few kilometers north in Saltdal Fjord, there was a ferry. Further north in Salten there were also many longer ferry connections. In December 1941, the Germans demanded forced road construction and offered prisoners to the Directorate of Public Roads to carry out the work. It was agreed to prioritize the three road systems in Korgen, in Botn in Saltdal, and around Beisfjord in Ofoten.
