Artist Henk Hofstra created an "urban river" in Drachten (Netherlands). The Blue Road installation is an example of what mind-blowing urban public art can be. Featuring 1000 metres of road painted blue and 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.
