Bengaluru's notorious traffic congestion, particularly at the Hebbal junction, is once again under the spotlight as authorities propose new infrastructure projects to alleviate the persistent gridlock. Among the latest initiatives is a plan for a new tunnel road, aimed at easing traffic flow and improving connectivity in the area.
Karnataka's Deputy Chief Minister D.K. Shivakumar recently announced a proposal to construct a 1.5-km underground road at the Hebbal junction. This initiative is designed to specifically target the severe traffic congestion that plagues this critical intersection, a major bottleneck for commuters traveling between North Bengaluru and the city center.
Another 2.2-km underground tunnel project is also in the works, with the aim of reducing traffic on the Hebbal flyover and providing a direct link between Kempegowda International Airport and Mehkri Circle. This tunnel will begin near the Nadaprabhu Kempegowda statue at the Hebbal flyover junction and pass under Tumakuru Road before emerging at the Veterinary College grounds. From there, it will merge with Ballari Road.
These projects are separate from the already planned 16.75-km elevated corridor running between Hebbal and Central Silk Board, and the twin-tube tunnel corridor connecting Hebbal to Central Silk Board Junction, and KR Puram to Mysuru Road. The Bangalore Development Authority (BDA) will independently execute the shorter 1.5-km tunnel, while Bengaluru Smart Infrastructure Limited (B.SMILE) is progressing with the elevated corridor.
In addition to the tunnel proposals, a new loop on the Hebbal flyover is nearing completion and is expected to be operational soon. This loop, designed to facilitate smoother entry into the city from Nagawara, is anticipated to open before August 15, pending the Chief Minister's schedule. An additional loop will also link the airport service road to the city loop, with its opening date to be confirmed later.
While these infrastructure upgrades are welcome news for commuters, some experts are urging caution. Concerns have been raised that relying too heavily on tunnels and flyovers may only provide short-term relief and could potentially lead to increased traffic congestion at other points in the city. Some experts advocate for strengthening mass transit systems like the suburban rail and metro as more sustainable, long-term solutions.
Adding to the debate, BJP MP Tejasvi Surya has voiced strong criticism of the city's tunnel-focused solutions, suggesting that Bengaluru should avoid repeating the mistakes of other global cities. He noted that Singapore abandoned similar mega-tunnel plans after realizing they were costly, unsustainable, and ineffective at easing congestion and urged policymakers to consider more sustainable alternatives.
The urgency for these projects is highlighted by data indicating that the average one-way commute in Bengaluru has increased by 16% over the past year. In 2024, the average commute time was 54 minutes, but by mid-2025, it has risen to 63 minutes for the same 19-km distance.
As Bengaluru continues to grapple with its growing traffic woes, the proposed tunnel road and other infrastructure projects at Hebbal junction represent a significant effort to improve connectivity and reduce congestion. However, it remains to be seen whether these measures will provide lasting relief or if a more comprehensive approach, including investments in mass transit, is needed to address the city's traffic challenges effectively.
