Small museum of Norwegian Roads and traffic regulations. Very kids friendly and takes about an hour to visit. Great parking. Friendly staff.

Way more interesting than the name suggests. Anyone with an interest in transport and or engineering could easily pass half a day here and still have things left to see. It is really two (or more) museums in one. Firstly the construction and maintenance of Norway's road network through time (many machines outdoors, plus a rock tunnel exhibit and indoor exhibition), but also a record of life on and by the road including old buildings transported to site and reassembled - I think the English translation "road" doesn't fully do the Norwegian idea justice... The staff are knowledgeable and enthusiastic, keen to explain or run some of the various mechanical exhibits...anyhow, it is entirely free to visit, so give it a try if you are nearby.

Super fantastic place to visit. Worth 3 hours road trip from Oslo

For those interested in road construction and ways of transport from 0 - 2018 is this a good place. The entry is free and the museum is technically well equipped.

The Norwegian Road Museum is a good place to stay for a couple of hours. Walk through the mines, see giant vehicles, enjoy a small tour with an old bus and get educated about the history of Norwegian Road and traffic.
