Bengaluru office park owners are investing in transport links as GCCs drive demand for workplaces with easier commutes. Bagmane Prime Office REIT committed ₹40 crore to co-develop Bagmane DRDO Sports Complex Metro Station and will upgrade its amenities and facade. It is building a rail-over-bridge linking its Whitefield assets to Outer Ring Road, avoiding crossings that add 15–20 minutes, and has built flyovers and walkways connecting Bagmane Tech Park and Bagmane Cosmos.

The ITPB Metro Skywalk, opened earlier in 2026, links Pattandur Agrahara Metro Station to International Tech Park Bangalore and Park Square Mall, serving over 55,000 professionals; CapitaLand India Trust partnered with BMRCL. Prestige Group completed a 1.5-km flyover between Outer Ring Road and Old Airport Road and will build Bellandur metro station near its upcoming 8-million-sq-ft Prestige Lakeshore Drive campus.

Embassy REIT spent ₹100 crore on Kadubeesanahalli Metro Station and ₹183 crore on a 1-km public flyover beside Embassy Manyata Business Park, serving over 100,000 employees. The station is on the 17-km Outer Ring Road corridor between Central Silk Board and K.R. Puram. India recorded 66.4 million sq ft of office leasing in January–September 2026, up 8%; GCCs leased a record 28 million sq ft, or 42%.

Bangalore Metro Rail Corporation Limited is preparing a detailed project report for a proposed 16.3-kilometre KR Puram–Hoskote corridor with 11 stations: ITI Bhavan, TC Palya, Bhattarahalli, Bhattarahalli Junction, Medahalli Junction, Avalahalli, Budigere Cross, Katamnallur Gate, Hoskote Toll Plaza and Hoskote Government Hospital. The route is prioritised from KR Puram rather than as a direct Purple Line extension from Kadugodi. Its reported internal rate of return is 19%.

High-speed rail stations are planned at Hoskote for the Bengaluru–Chennai and Bengaluru–Hyderabad corridors. Near Kodihalli, a depot, workshops and operations control centre are being considered, potentially requiring 80 hectares. The Bengaluru–Chennai Expressway is open between Hoskote and Baireddypalli in Andhra Pradesh for about 100 kilometres. Highway traffic could exceed 80,000 vehicles after the Satellite Town Ring Road links to Hosur Road; a double-decker metro and road-flyover arrangement has been proposed.

Separately, BMRCL is building a 420-metre elevated section between Whitefield station and Milan Road for Rs 64.81 crore. Buildtek holds the contract, with an 18-month deadline.

Hoskote, about 30 km east of Bengaluru, is emerging as a transport gateway to the city. Plans include a proposed 17-km Namma Metro extension from K.R. Pura to Hoskote along Old Madras Road on Kolar Highway, high-speed rail corridors and a Bengaluru–Chennai Expressway. A high-speed rail station is also proposed for the area.

Bengaluru has proposed six Metro extensions:

• Purple Line: Challaghatta to Bidadi, about 15 km; KR Puram to Hoskote, 16 km.
• Green Line: Silk Institute to Harohalli, 24 km; Madavara to Tumakuru, 59 km.
• Yellow Line: Bommasandra to Attibele, 11 km.
• Pink Line: Kalena Agrahara to Kadugodi Tree Park, about 68 km.

The Tumakuru extension is undergoing a detailed project report (DPR) process; its feasibility report has been submitted. The other five proposals await government approval, after which feasibility reports would be prepared and submitted, followed by DPRs if approved. The extensions aim to improve access to industrial areas, employment corridors and educational institutions, save travel time and reduce traffic. BMRCL recently finalised a contractor for a short Purple Line extension intended for train maintenance.
