RVNL seeks final traffic blocks at Chingrighata in Jan
Times of India | 27 December 2024
Kolkata: RVNL has sought traffic blocks at Chingrighata for one last time to facilitate Metro construction. The overnight blocks will be implemented between 10 pm and 7 am in two phases — for five days each in Jan-end. The railways PSU has commenced constructing a new road through which vehicles will be diverted while the ongoing girder-launching work for the Orange Line reaches the crucial Chingrighata crossing.
The new thoroughfare — 5.5m wide and 550m long — will link Captain Bheri and Chingrighata, passing via the Dhapa Lockgate and below the Chingrighata flyover. Vehicles will be directed through this stretch when the night blocks are implemented in Jan, sources said. Both the flanks — Ultadanga-bound and New Garia-bound — at Chingrighata crossing will be closed to traffic.
TOI reported earlier that after seven years of struggle over site acquisition and some other impediments, RVNL, implementing agency of most of the city's Metro projects, has finally started work to bridge the 568m gap at Chingrighata. The first girder span — between piers 310 and 311 — opposite Caption Bheri on EM Bypass was launched on Tuesday night.
Girder-launching for a bridge or Metro viaduct (elevated concrete or steel structure on which tracks are laid) involves machinery (weighing no less than 400MT) to lift heavy precast segments or concrete spans and position them sequentially to assemble a continuous structure. RVNL has informed traffic officers that night blocks, spanning five nights in two phases, shall be a prerequisite for the viaduct construction above the busy crossing. The traffic blocks may be in place in Jan when girder-launcher reaches the crossing to bridge piers 317, 318 and 319.
