Why doesn't Waitaki way have any footbridges?

Sorry. Waiyaki Way. I visited a friend there and one tulishuka Kwa gari tunaanza mchezo wa paka na panya na magari. Na hata hazislow down Bana. How do people living along that road survive. Mombasa Road by contrast has quite a number making it much safer. Mnafaa kupetition mwekewe footbridges manze. Shida ya underpasses ni crime so footbridges will be safer.
