Entrance tunnel at Karahnjukar
The entrance tunnel lies under the Karahnjukar dam. The project was to build the 720 m long tunnel into the west bank of Jokulsa in Dal under the location of the dam at Karahnjukar, below the dam in Hafrahvammsgljufur.
The tunnel is is 6 m high and 6 m wide with 13,5% gradient in under the dam.
IAV set up an internet connection through a satellite for the project Road to Karahnjukar in the fall 2002, a telecommunication station to serve IPC’s employees. This was a 512 Kb connection through a Eutelsat- satellite with a
IP-telephone. This station was at 730 m above sea level and therefore the station at the highest elevation in Iceland.
