The project comprises the construction of 3,25 km of a new national road 9 through Skomedal in Bygland municipality in Aust-Agder county. The new road route mainly lies in the hillside to the west of the current national road, except the last kilometre, where the new road route will approx. follow the current route. The work will mainly consist of the removal of matter, blasting, plumbing work, asphalt work, railing work, etc. 2 bus lay-bys shall also be established. The new national road 9 shall have a width of 7,5 m and it shall mainly be built on a filling. On 2 stretches the line has an extended profile where rock shall be taken out for a stone filling and frost protection layer. Some of the uncompacted matter in the line shall be used for refilling areas where rock has been taken out. In addition to the new national road 9, approx. 1 000 m of operational roads shall be constructed.
