North Bengaluru's rapid growth has placed increasing pressure on its road infrastructure. Hennur - Bagalur Main Road, an important alternative route to Kempegowda International Airport (KIA), is among the stretches experiencing this change. To address traffic congestion and infrastructure deficiencies, the government is undertaking a redevelopment project involving white-topping, drainage improvements, footpath development and junction upgrades. These changes aim to improve everyday connectivity for residents, commuters and airport travellers.

Why Is Hennur-Bagalur Road Being Upgraded?

Once surrounded by agricultural villages, the Hennur - Bagalur corridor has developed into a busy urban route. The opening of KIA increased demand for alternative airport connectivity, while the growth of high-rise apartments, commercial establishments and residential communities brought more vehicles onto the road.

However, the existing infrastructure has struggled to accommodate this demand. The redevelopment aims to improve road durability, manage increasing traffic and provide safer movement for both motorists and pedestrians.

Current Challenges Along the Road

Several infrastructure problems have affected the corridor:

• Traffic congestion: Increasing vehicle volumes have created bottlenecks, particularly around Geddalahalli Junction and other busy intersections.
• Poor road conditions: Uneven surfaces and potholes have affected driving comfort and safety.
• Waterlogging: Inadequate drainage has caused rainwater accumulation during monsoons, inconveniencing pedestrians and motorists.
• Pedestrian safety: Damaged footpaths and limited walking space have made movement difficult for pedestrians.
• Construction delays: Work that began in April 2025 has missed multiple deadlines, with dust, incomplete road sections and construction disruption affecting local residents and businesses.

What Does the Redevelopment Include?

Bengaluru Smart Infrastructure Limited (B-SMILE) is executing white-topping across a 4.6 km stretch at an estimated cost of ₹86 crore. An additional ₹6 crore has reportedly been requested to extend the work by another 600 metres.

The project includes four major improvements:

• White-topping: Replacing the existing surface with durable concrete, potentially reducing recurring potholes and maintenance for approximately 15 - 20 years.
• Drainage upgrades: Improving roadside drains and stormwater systems to facilitate rainwater flow and minimise waterlogging.
• Footpath development: Repairing and restructuring pedestrian pathways to provide safer walking spaces.
• Junction improvements: Introducing location-specific traffic solutions to ease congestion and improve vehicle movement.

An elevated corridor or shorter flyovers at selected junctions are also under consideration. These proposals aim to address traffic bottlenecks, although the government has indicated that further infrastructure must be justified by traffic studies.

Who Will Benefit From the Upgrade?

The improvements could benefit several groups across North Bengaluru:

• Local residents: Communities in Hennur, Horamavu, Chikkagubbi and Bagalur could experience better road access, drainage and pedestrian facilities.
• Daily commuters and IT professionals: People travelling to nearby employment centres, including Manyata Tech Park, could benefit from smoother journeys and improved junction management.
• Airport travellers: Motorists using this alternative connection to KIA could benefit from improved road conditions and connectivity.
• Students and families: Better footpaths and safer junctions could make everyday school journeys more convenient.
• Local businesses: Improved accessibility could support customer movement, deliveries and commercial activity.
• Property owners and developers: Better connectivity and civic infrastructure could strengthen the appeal of surrounding residential and commercial areas.

How the Corridor Became an Important Route

The Hennur - Bagalur stretch gradually transformed from a rural road connecting agricultural villages into an important urban transport corridor. Following the development of KIA, it was identified as an alternative airport route, giving motorists another option besides the main airport highway, particularly those seeking to avoid its toll charges. The current redevelopment represents a broader effort to address these infrastructure shortcomings.

Improving North Bengaluru's Connectivity

The Hennur - Bagalur Road upgrade aims to address more than traffic congestion by bringing road quality, drainage and pedestrian safety into a coordinated improvement plan. With December 2026 set as the revised completion target, its impact will depend on timely execution and the effective delivery of the proposed infrastructure.
