In the Netherlands, it's 500 meters of TRON.
In 2012, Dutch artist Daan Roosegaarde and civil engineering firm Heijmans promised to install the first glow-in-the-dark road in the Netherlands by mid-2013. Now, well into 2014, the concept has finally come to life in Oss, a city about 60 miles southeast of Amsterdam.
The photo-luminizing markings, which absorb daylight then release a green glow for up to eight hours in the dark, were recently unveiled on a 500-meter stretch of highway.
This is one of several technologies Roosegaarde and Heijmans envisioned with their "Smart Highway" project, which dreamt of self-sustainable and interactive roads. Other wild ideas (like snowflake symbols that would manifest on the street surface when temperature hits a certain low) did not make it into this pilot stage.
According to the BBC, an official launch for the glow-in-the-dark road is set for later this month. DutchNews.nl reports that Roosegaarde also wants to light up additional roads, but so far hasn't negotiated any more contracts.
