good news but it came very late and after starting of the project it will take max 5 years to complete 1st phase. kindly work on priority basis and complete it as soon as possible. apart from this patna also need at various places underpasses so that traffic interruption get less. with all roads there should have side parking area and foot path so that people can walk there only and not on roads. people have to understand the traffic system and have to educate themselves to not disrupt vehicles.
at last i want to say educate from now only how to use metro and dont give dharna's on metro tracks also....
