Mysore road expansion - how can you remove the bottleneck?

Do planners in Bangalore realize that bottlenecks are the main source of traffic problems? It doesn't matter if you have a 5km long 8 lane road at the end of which has a bottleneck which reduces to 2 lanes. 

It looks like that the Mysore road is going to be widened. The govt will end up spending crores of money and cause inconvenience to lot of riders during this widening spree. We'll also lose all the trees which so far have kept the Mysore road a complete canopy. But the Bapujinagar bridge is a huge bottleneck. If nothing is done to widen at this point, the whole effort is meaningless. Given that we have the Masjid and the GhaaLi Anjaneya temple on either side, we can imagine that this part of the road can never be widened. 

Do the officials even think about this before going about doing their job of road widening?
