Ontario Police Sgt. Kerry Schmidt just posted a notice to drivers on Twitter that southbound lanes of ON Highway 400 are now blocked. The closure is in effect at the King Road exit in the GTA, approaching Newmarket. The reason, according to Sgt. Schmidt, is spilled sewage waste.\nREAD ALSO: 70-Vehicle Pileup Causes Massive Shutdown Of Ontario's Highway 400\nVia ON-400 & King Rd. | Google Maps\nAbout 25,000 litres of sewage was spilled onto the highway sometime in the mid-morning on Wednesday.

Last April, human waste forced a shutdown of the highway near Barrie after it spilled from a tractor trailer. The spill was caused by the driver suddenly slamming on his brakes.\nCTV News reported at the time that it took Ontario's Ministry of Transportation several hours to clean up the mess. But, they didn't let the waste go to waste, of course - they transported it to a facility where it was converted into fertilizer.\nLet's hope that the cleaning crew is able to get this situation taken care of quicker than last time.
