BMRCL has for the first time taken a very positive step by sharing the dpr for the phase 2a which connects Central Silk Board to KR puram (via ORR) on the internet.
They have also invited review comments by the general public. We have time till end of this month.
The document can be accessed here.
One of the first thoughts that comes acorss is the document mentions that the metro line will pass through the median on most part of the ORR and hence there is very less need of additional land for building the pillar/viaduct. However, this stretch specifically btw Silk board and Marathalli was actually prepared for a BRT lane in the middle of the main carriageway. Hence we have the many short bridges with lanes sapareted with 2 lane road at grade.
Hence if the metro is built in the middle, this at grade road section btw the bridges will be come unusable almost totally. Hence a plan to make the road, at least a section of it still usable, would be useful!
Maybe a cantelever kind of design for the pillar could be used to keep one lane at grade usable.
There will be many such review points about the DPR. Request to share and discuss here, so that we can consolidate and forward it to BMRCL.
