People who have travelled outside India to USA, Canada, European countries, China, Japan would have seen huge exit boards indicating where which exit will take the driver. In India, it was unimaginable until Golden Quadrilateral became a reality. Today, I post some of these pics showing exit boards on Delhi-Gurgaon Expressway and Delhi-Noida expressway. Enjoy the sign boards. Also, watch out for bright LED display boards for Smart Tag users to get automatic toll deductions from devices, like SUNPASS in Florida, USA.
One could not have imagined before Golden Quadrilateral, sign boards of the ones below would be visible on Indian roads, esp the part wherein distances are displayed in kilometers and that too in 1000's . Observe the images carefully: (All photos from skyscraper.com)
