For the 47 km Chennai Metro Line-5’s Adyar River Bridge connecting the neighbourhoods of Manapakkam and Nandambakkam, Larsen & Toubro constructed the first 9.5m wide pier cover.
Under Chennai Metro’s Phase 2 project, the new, primarily elevated Line-5 will link Madhavaram and Sholinganallur via 48 stations. To connect CMBT and Puzhuthivakkam, the 12.431 km long Package C5-ECV-02 viaduct by L&T will bridge the Adyar River.
Adyar River is approximately 100 metres wide at this location (see on Google Maps), and Line-5’s bridge has 6 piers: 4 inside the river and 1 on each bank.
L&T was awarded C5-ECV-02’s Rs. 1656 crore contract in November 2021 with a 36 month deadline.
This section’s viaduct and 12 sections are located right in the middle of Line-5. It consists of 2 disjointed sections on either side of the double-decker Package C4-ECV-01 (Power House – Porur) which was awarded to Larsen & Toubro in May 2021.
