Delhi Transport Corporation [DTC] — Missing route

My name is karan. I usually take bus no 764b express from munirka to reach nehru place so that i can reach before / on time as express bus always use the flyovers which saves lots of time because of avoiding traffic signals below flyovers. And that too express bus charges rs. 20 for any distance and no dtc pass is accepted but now as the drivers are instructed not to use flyovers then what is the difference between normal bus and express bus? my time and money both are getting affected because of this new rule/instruction.
