In an effort to alleviate congestion at the crucial Central Silk Board (CSB) junction and establish it as a signal-free intersection, the Bangalore Metro Rail Corporation Limited (BMRCL) is currently undertaking extensive construction work. A significant aspect of this endeavor involves pouring concrete non-stop for 50 hours to place a solid slab for a road flyover at the CSB Junction. This marks the first time such a task will be executed, with work set to commence on Thursday.
N Sadashiva, Deputy Chief Engineer of the Outer Ring Road (ORR) Line at BMRCL, highlighted the scale of the operation, stating, “This will be the first time something of this nature is being undertaken. For the past two months, 10,100 workers have been engaged in ramp-related works. We have collaborated closely with the traffic police due to the heavy traffic flow at this junction.”
The project has been contracted to AFCONS Infrastructure Limited by BMRCL.
The CSB junction serves as a vital link between BMRCL’s Phase-2A line, extending from CSB to KR Pura station (Outer Ring Road Line), and the Yellow Line, connecting RV Road to Bommasandra. To alleviate traffic congestion, a road flyover, along with five loops and ramps totaling a length of 3km, are being constructed at CSB Junction.
The first level of the road flyover, serving the Reach-5 line (from Ragigudda to CSB Junction), has already been completed, with ramps A, B, and C scheduled for commissioning by May of this year. Ramps D and E are expected to be operational by December, as stated by the Deputy Chief Engineer.
Providing further details, Sadashiva outlined the extensive components involved in the construction process. “A total of 2,520 cubic meters of solid slab will be placed on the ramp, which will have a running length of 124 meters and a width of 15.1 meters. The depth of the slab will be 1.8 meters. Additionally, 245 tonnes of steel, 225 high tensile steel strands, and 11,074 high-density polyethylene pipes are being utilized,” he added.
