The Baranagar to Barrackpore, 12.50 km (7.77 mi) metro corridor (Line 5)^[1] in North 24 Parganas, is another line of Kolkata Metro, in Indian state of West Bengal. It was sanctioned in 2009, at a cost of Rs.2070 crore,^[3] to enable a quicker commute from the northern suburbs to Kolkata, via North Kolkata.

State government proposed for realigning the line via Kalyani Expressway, instead of B.T. Road, due to the presence of arterial water pipelines, that supply water to the city, below BT Road. The construction might create huge traffic jam along the road and also damage the water pipelines, which will cutoff the city's water supply. This will increase the length to 17 km (10.56 mi). .^[3][5] This proposal is not feasible as fresh sanctioned from rail way board was required . It would provide the eassy movement to the residents near by BT Road which is huge traffic congesent . There are 6 nos pipe lines of 64'', 72'', 42'',60'' 48'' & 62'' diameter have been laid in the year 2012, 1957-61, 1868-84, 1922-36, 1888-93 1971-96 respectively. Arrangement of pipe lines are east to west sidesunder BT road. ROW of BT Road is average 40-42 m. KMC'S Engineers views that constructions of central pier system metro stations like others metro cities is possible. on diverting the flow of existing 48'', 60'', & 42'' pipelines on laying one by one new pipe line.

Accordingly Project implemeting agency RVNL has submitted the revised sequence of construction as under .

      1. Laying an additional 60 inches diameter pipe line between Baranagar (Dunlop Bridge) to Barrackpore (Chiriamore) and installation of connection of newly laid 60 inch diameter (MS welded pipe line by Micro Tunneling Method) with existing old 60 inch diameter pipe line and existing 48 inch diameter old pipe line by means of butterfly valve arrangement after taking shut down in stages to suit the site requirements.

        2. On diverting flow of existing 48 inches pipeline through the newly laid 60 inches pipe line, the work along this pipe line (Casting of pile and realignment of 48 inches pipe line by DI pipe) will be taken up.

          3. On completing the mentioned work along existing 48 inches pipeline,  the flow of this pipe line will be restored as earlier and the flow of existing   60 inches pipeline will be diverted through the newly laid 60 inches diameter pipe line to defunct this pipe line. The casting of pipe, pile cap and other structural work will be taken up along this 60 inches diameter pipeline on defunct condition without disturbing the 42 inch diameter pipe line as it is not infringing / influencing Metro construction and installation. It is also proposed that the entire work will be done in two phase ie. 1^st phase Baranagar to Gandhi Ashram Metro station and 2^nd phase remaining portion.
