I made a presentation yesterday to Mr.Subramanya (BBMP Commisioner) at his office about the single bus lane idea. He was quite interested and said he would discuss with his committee and revert. He also agreed very well that the solution was not to build or widen more roads or flyovers. He also mentioned some problems that are being faced with the underpasses construction on Bellary road - the actual costs were much higher than anticipated because numerous problems had cropped up - conduits for sewerage, water, telephone, electricity, etc that were marked incorrectly on admittedly very old drawings that now need to be re-aligned !
