Emergency services transported one person to Ullevål Hospital following a serious traffic collision on National Road 159 in Rælingen municipality. The accident occurred Monday morning near the Rælingen Tunnel heading toward Lillestrøm.
Police operations leader Endre Metteson Aulie confirmed the incident appears serious. Authorities received the emergency call at 5:12 AM.
The collision involved a rear-end crash before the tunnel entrance. One lane remains closed past the accident scene as investigation continues.
Rælingen sits in Akershus county, just northeast of Oslo. National Road 159 serves as a key transportation route connecting this suburban area to the capital region.
Road closures during morning rush hours typically create substantial delays for commuters. The timing of this serious accident will likely affect traffic patterns throughout the eastern Oslo metropolitan area.
Emergency response teams continue working at the scene. Motorists should expect delays and consider alternative routes until authorities fully reopen the roadway.
