Oslo residents and commuters should anticipate significant traffic disruptions on Tuesday and Wednesday due to extensive security measures surrounding the state funeral of King Harald. The Norwegian Public Roads Administration advises people to avoid driving, forecasting severely congested conditions throughout Oslo, and on roads leading into and out of the capital. Road closures, both partial and complete, are expected, potentially with little notice, causing substantial queues on main routes. Alternative routes may also experience delays. These measures are in place to facilitate the extensive security arrangements for the Wednesday funeral proceedings. Travelers are urged to plan accordingly and consider alternative transportation methods.
