Are Chandigarh's infra project timelines just a myth?

Builder marketing around these 'upcoming' infrastructure projects is just pure fraud sometimes. I bought a 3BHK in Zirakpur, near that PR7 Airport Road stretch, two years back. SBP Group bola tha ki completion is almost done, connectivity will be amazing by now. My kids' school admission bhi ussi expectation pe kiya tha. Now, the road work is still pending, traffic jam ki halat kharab hai. Matlab, two saal ho gaye, aur abhi tak no clear timeline. My wife is so upset about the commute, aur safety ka bhi concern hai for the children. Is it just me facing this? Or are these Mohali International Airport expansion and New Chandigarh Master Plan timelines also equally delayed? Honestly not sure if any of these mega projects will ever finish on time. Should I just sell this flat and look for something in Sector 49, even if it means shelling out more? Kya karein yaar, bahut frustrated hoon.
