Henk Hofstra’s Blue Road, Netherland

This news is old but worth checking out. On April, 2007, Dutch artist Henk Hofstra painted a 1000 meter stretch of road in Drachten, Netherlands, blue.

The blue painted road features the phrase "Water is Life" written in eight-meter-high letters across it. The Blue Road is reminiscent of the waterway that used to be where the road is now. It's a memorial to nature, but it's also just plain awe-inspiring. There's even a few cool tidbits along the road, like a sinking car.
The project took 4000 liters of paint and cost 75,000 Euros. Half of the cost was covered by municipal funds.
