It passes by Hustadvika, an unsheltered part of the Norwegian Sea, connecting the island of Averøy with the mainland and Romsdalshalvøya peninsula.

It is built on several small islands and skerries, which are connected by several causeways, viaducts and eight bridges—the most prominent being Storseisundet Bridge.

The road was opened on 7 July 1989, having cost 122 million Norwegian krone (NOK), of which 25 percent was financed with tolls and the rest from public grants.

It is a popular site to film automotive commercials, has been declared the world's best road trip,[2] and been awarded the title as "Norwegian Construction of the Century".

Planning of the Rauma Line to connect the national railway network to Møre og Romsdal was under way, and several proposals were made to extend it to the coastal towns.

In 1921, Møre og Romsdal County Council chose the outer route, which would have followed a path close to that of the road.

Arne Rettedal, who was Minister of Local Government and Regional Development in the early 1980s, proposed that job creation funds could be allocated to road projects.

[5] There was significant local opposition against toll financing, as few people believed it would be possible to pay off the road in the stipulated 15 years.

[2] The road has become a popular place for the automotive industry to film advertisements; more than ten manufacturers have made television commercials along the route, often depicting the harsh weather.

For bridges, it lists the name, overall length and clearance below; for junctions, the distance from the starting point and the name of the road it intersects with.
