Norway was not affected by WW1 directly, but Hitler occupied Norway during WW2. When the Soviets came to the rescue, the Germans burned down everything as they withdrew from the northern parts. The most populated areas were largely not affected though. As for infrastructue, Norway was one of the poorest contries in Europe 100 years ago, with similarly poor infrastructure - so it was not a matter of rebuilding, rather a matter of building. In this sense oil helped, and foreign oil investments were welcome in the late 60s, but at a 78% tax rate.
