Pixie dust on the road?

In Iceland, work on a road construction project was halted over fears that this would cause upset to the elves present in the area. The local council stepped in as work got underway, showing concern that the road building activity would scare away the elves and bring poor fortune to the region. A firm decision was taken, to stop the road building and leave the elves in peace. Trolls however commented adversely on the internet on the grounds for the decision.
