The works include the regulation, engineering design and construction for a mainland connection between Helgøy and Mosnes. Helgøy is situated in Hjelmeland Municipality.
The project includes approx. 1 800 metres 1-lane road with meeting points, including the crossing of Helgøysundet (Helgøy strait) with a length of approx 250 metres in a straight line. The contractor must choose how the strait shall be crossed; by sea filling with a minimum entrance for small vessels in accordance with the sketch:
‘Minimumskrav seilløp’ (‘Minimum requirements sea lane’), combined filling/bridge, or bridge over the entire strait. The strait that must be crossed has various depths. However, the deepest point of the strait is 29 metres. A stretch of approx. 250 metres with rock cuts is located just north of the strait. The cut has different heights. However, the highest point is approx. 16 metres. At Helgøy the 340 metres road is completed up to the road's planum. The commenced road must be completed with a road development up to and including a surface of asphalt, completion of road ditches, side terrain, etc.
The project will be implemented model-based.
