The Bruhat Bangalore Mahanagara Palike (BBMP) has proposed improvements to the flyover across the Central Silk Board (CSB) junction.
The improved version would look like the Hebbal flyover.
While the Hebbal flyover provides smooth entry in to the city from the north, west and east, its counterpart on the southern end of city, the CSB flyover, only provides access to Electronic City.
The CSB junction connects the Outer Ring Road (ORR) and NH7.
Traffic scene on ORR below the flyover has worsened over the years. A study by the BBMP has found that the CSB junction handles 18,116 passenger car units (PCU) of traffic during peak hours.
This is much higher than the traffic load of 10,000 PCU per hour, recommended by the Indian Road Congress (IRC).
The congestion has made it difficult for traffic plying on HSR layout and BTM layout city routes.
The BBMP has estimated the traffic pile up on BTM layout at 450 metres. The BBMP proposal to ABIDe include three options to integrate traffic on ORR with that on the flyover above and thus eliminate the need for traffic signals.
All options propose setting up of new infrastructure on the HSR layout side.
One option is to have four loops from the ground level to the flyover along with two dedicated roads to and from the HSR layout end.
The next option is to have two loops and dedicated roads, while the last option is to have three loops and the dedicated roads.
Sources in the BBMP engineering department said they were also considering having just one loop of the road connecting from the ground level road to the flyover along with improvements to the existing roads.
BBMP chief engineer Krishna Reddy said the proposal was sent to ABIDe and the work would be put to tender after its clearance.
ABIDe View, ABIDe member and traffic expert, Prof MN Srihari said that infrastructure was the need of the hour, especially when the elevated corridor to Electronic City from CSB junction is about to be commissioned.
“When you have heavy traffic on the elevated corridor arriving at the CSB junction, it would be impossible for the traffic below the flyover to move. We must complete this project to coincide with the completion of the elevated corridor,” he said.
Prof Srihari also opined that ABIDe would also consider an option to have an underground connectivity instead of the proposed elevated loops.
