Grønnlifjell Tunnel
The Grønnlifjell Tunnel ()  is a road tunnel that is part of Norwegian County Road 830 in the municipality of Fauske in Nordland county, Norway. It is located between Finneid in the town of Fauske and the village of Sulitjelma. This tunnel is part of a series of three tunnels on this road. The Sjønståfjell Tunnel and the Hårskolten Tunnel both lie to the east of this tunnel. The  long tunnel was originally built in 1956 as part of an expansion of the Sulitjelma Line between Finneid and Sulitjelma. The railway line was closed and dismantled in 1972. The tunnel was rebuilt soon after when the old railway line was converted into a highway which opened in 1975. See also
