Replacement bus between Berg and Sognsvann continues for one more week

Work on the Sognsvann Line is one week behind schedule, and there will be a replacement bus service between Nydalen and Sognsvann next week as well, until 24 August. The delay is due to the need for more time to ensure that the new Berg Bridge meets all quality and safety requirements.

For travelers to Tåsen, Østhorn, Holstein, Kringsjå and Sognsvann, a replacement bus runs from Nydalen. Travelers to Berg are referred to Tåsen or Ullevål. The Ring line operates as normal between Ullevål stadion and Nydalen.

Buses replace the metro to Sognsvann this summer

From 6 July to 16 August, the metro will not run between Majorstuen and Sognsvann, or between Majorstuen and Nydalen. The reason is upgrade work on the Sognsvann line.

This means that nine stations will have no metro service during this period: Sognsvann, Kringsjå, Holstein, Østhorn, Tåsen, Berg, Ullevål stadion, Forskningsparken and Blindern.

If you are travelling to or from one of these stations, you must use a bus instead. Two replacement buses are running: 5B between Majorstuen and Sognsvann, and 4B between Majorstuen and Nydalen. The buses stop at their own designated stops. Check stop and departure time in the journey planner.
