"Blue Road", Netherlands
Last April, 2007 Henk Hofstra created an "urban river" in Drachten, The Netherlands(Holland). 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-metre-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 litres of paint and cost 75,000 Euros. Half of the cost was covered by municipal funds. Hofstra wants the road to be visible on Google Earth, but it hasn't shown up yet.
