The Blue Line of Namma Metro is a proposed MRTS line, will be under construction from December 2020 under Phase-2A and from March 2021 under Phase-2B and will form part of Reach-7 (R7) of the metro rail network for the city of Bangalore, Karnataka, India. The 56 km line connects Central Silk Board with Kempegowda International Airport. The Blue Line is mostly elevated but also has an at-grade (surface) section close to Airport and a small underground section where it passes Yelahanka Airport belonging to IAF. There are 30 stations on the line of which the two station/s at the Airport may be on surface or underground. Blue Line will have interchanges with Yellow Line at Central Silk Board terminal station, with Purple Line at KR Puram station and with Pink Line at Nagawara. The extension of Purple Line passing through KR Puram is under construction. Pink Line is also under construction. Just like the Pink and Yellow lines, this train will run on autopilot by CBTC, unlike the current Purple and Green lines which run with a driver inside the train and by distance to go.
History
The routes under Phase-2A and Phase-2B (Blue Line) were actually part of Phase-3 but 'fast-tracked' and prioritized under Phase-2. As early as in February 2012, the Central government had also requested BMRC to start work on the airport link during Phase 2 itself.[1][2]
The route from Central Silkboard to K R Puram along the eastern part of Outer Ring Road (ORR) was included as Phase-2A since development on that part of ORR had leap-frogged much ahead of the rest of the city with huge number of new office buildings. As a result, traffic increased several fold with employees traveling from different parts of the city to this new CBD. Chief Minister of Karnataka, Siddaramaiah announced in September 2016 that a new 18 km (11 mi) line connecting Central Silk Board with K.R.Puram along ORR would be included in Phase 2 as Phase-2A of the project at an estimated cost of ₹4202 crores.[3][4]
Kempegowda International Airport (opened during May 2008) being very far from city center (about 35 km), commuting time by road in traffic congestion is time consuming. Hence, attention for building a fast mass transit was in the minds of planners from the beginning, especially since air traffic had kept increasing.
To connect airport to city, there had initially been a proposal to build a 33 km (21 mi) high speed rail line from MG Road to Kempegowda International Airport (KIA). Cost was estimated at ₹5,767 crore (US$810 million). This was to be executed by an independent SPV - Bangalore Airport Rail Link Limited (BARLL).[5] However, the plan for an exclusive city-airport high speed rail was canceled during October 2013 due to high cost and viability concerns.[6]
It was decided that BMRC would manage the airport rail project and a regular metro line with fewer halts would be built instead of a high speed rail. Following this, suggestions were invited from public during September 2016 to choose any one of nine possible extension routes from existing and proposed metro lines to the airport.[7] The proposed extension routes had an average length of 30 km (19 mi), and cost estimates ranged between ₹4,500 crore and ₹7,000 crore. A 25.9 km (16.1 mi) extension from Nagawara via Kannur and Bagaluru was the shortest, while the 35.4 km (22.0 mi) extension from Yeshwanthpur via Yelahanka, Kannur and Bagaluru was the longest of the proposed routes. BMRC received 1,300 responses from the public.[8] The shortest (25.9 km, 16.1 mi) extension of the Kalena Agrahara (previously Gottigere) – Nagawara line via Kannur and Bagaluru to the airport emerged as the most popular choice.[9] In February 2017, the Centre requested BMRC to start work on the airport link before Phase 3. Thus, the Airport Line was included in Phase 2 as Phase 2B.[10]
Since Bangalore International Airport Limited (BIAL) forbade underground construction from the southern side of the airport (due to security concerns as it would have to pass beneath the airport's second runway), the shortest route options (i.e. extending the Pink line from Nagawara directly north) were eliminated. An alternate route proceeding north till RK Hegde nagar and then turning west to Jakkur and then along Airport Road was explored. Bangalore Development Minister K. J. George announced on 12 May 2017 that the government had finalized the Nagawara-Ramakrishna Hegde Nagar-Jakkur-Yelahanka route to the airport.[11] However, this route had an obstacle as a high-pressure petroleum pipeline was passing through the originally proposed route.[12]
This was changed and on 10 January 2019, the State Cabinet approved a change in alignment for the proposed metro line to the airport. The new line would begin at Krishnarajapura (K.R. Puram) and be aligned along the northern part of ORR (Outer Ring road), passing Kasturinagar, Nagawara, Hebbal, and Jakkur before heading towards the airport. The line would be 38 km long, about 9 km longer than the route previously proposed, estimated to cost ₹10,584 crore (US$1.5 billion).[13]
Tendering
Phase-2A
BMRCL prepared the detailed project report for the proposed Central Silk Board - KR Puram Line and submitted the DPR to the state government on 28 October 2016. Phase 2A was approved by the State Cabinet on 1 March 2017.
Tenders for ORR (east) Metro line were called during February 2018 and IL&FS emerged the lowest bidder for all packages. However, the tenders were quashed due to cash flow problems and bankruptcy proceedings by the selected firm, IL&FS. A second round of tendering was done during December 2019.[14] The project cost was revised to ₹5994 crores.[14] Fresh bids were received by multiple firms during March 2020.[15][16] There are two packages. The first package included 2.84Km of ramps for a flyover at Central Silk board junction in addition to 9.859Km of viaduct with six elevated stations. The second package was for 8.377Km viaduct with seven elevated stations, 1.097 Km depot line and a 0.30 Km pocket track.
As of September 2020, BMRCL was still awaiting central government's approval for Phase-2A.[17][18] Hence tenders have not been awarded yet.
Phase-2B
DPR for the Airport Line had been prepared in September 2017[19][20] and cleared by Government of Karnataka in January 2019.[13]
Tenders for the Airport line were called during July 2020. There are three packages. The first package was for 11.003 km viaduct, including 281 mtrs viaduct beyond phase-2A with eight elevated stations and 650 mtrs link line to Baiyyappanahalli depot. The second package was for 11.678 km viaduct with 250 mtrs pocket track and two elevated stations. The third package was for 15.011 km viaduct, including 718.18 mtrs cut and cover portion in front of Yelahanka Air Force Station. All three packages include road widening, utility diversion and allied works.
Bettadahalasuru station would be built by Embassy group at a cost of ₹140 crore. Kempegowda International Airport is likely to fund the construction of two airport stations off the highway.[21][22] An MoU was signed between BMRC and KIAL for construction of the 4.95 km line and stations entailing an investment of ₹800 crore.
However, approval from Central Government has been delayed and as of September 2020, is still to be received.
Construction
Construction is expected to begin in December 2020 on the Phase 2A section and March 2021 on the Phase 2B section.
Funding
BMRC is raising ₹3500 crore from ADB for construction of the Blue Line (Phase-2A and 2B).[23]
Stations
The Blue Line will have 30 stations.
