Transportation
The area is well covered with public transportation. Part of the Sognsvann Line of the Oslo Metro is in Nordre Aker, exactly beginning at the station Blindern in the south to the terminus Sognsvann in the north. The line runs northeast from Blindern, but between Berg and Tåsen it turns to the northwest and north. At the station Forskningsparken the Sognsvann Line overpasses the light rail Ullevål Hageby Line, which comes from the southeast. The terminus of this line being John Colletts plass for many years, it was extended to Rikshospitalet in 1999.
Branching off from the Sognsvann Line between Ullevål stadion and Berg since 2006 is the Ring Line of the Metro. The Ring Line stops at Nydalen before heading southwards and converging with the borough border towards St. Hanshaugen. The station Storo is on the border between the boroughs. Storo is also a light rail station; the terminus of the Grünerløkka–Torshov Line and the start of the Kjelsås Line. Opened in 1934, the Kjelsås Line runs northwards towards the terminus at Kjelsås. Lastly, Kjelsås is also a station on the Gjøvik Line railway, so is Nydalen. The Gjøvik Line runs from Storo via Akerselva towards Kjelsås, and northwards into Marka.
Road transport is also important in the borough. The largest ring road in the city, Ring 3, cuts through Nordre Aker. The portion of Ring 3 located in Nordre Aker starts, in the west, exactly at the underpass of Gaustadalléen under Ring 3 (at Gaustadalléen station), and ends in the east at the Sinsen Interchange. It runs eastward until after Nydalen, when it turns steeply to the south. The road it crosses at the Sinsen Interchange is not located in Nordre Aker.
