Residents of Bengaluru are set for smooth connectivity as the Bangalore Development Authority finishes the critical Challaghatta railway underbridge. The feat is a milestone of the Major Arterial Road project, designed to link Magadi Road directly to the Bengaluru to Mysuru highway. The new route will cut through the Nadaprabhu Kempegowda Layout. Once operational, it will slash travel times and bypass notorious bottlenecks. With the final construction phase now underway, officials expect the entire route to be fully operational by April 2026.
Officials stated that building the underpass beneath a live railway line is a massive achievement. They said the engineers faced the high stakes challenge of working while Bengaluru to Mysuru trains continued to run directly above the construction site, reported The Times of India. The team used a box pushing method to slide eight massive concrete blocks into place. Each of these blocks weighed approximately 1,200 metric tonnes.
While such projects usually take six months, round the clock labor and coordination with South-Western Railway cut the timeline down to just three months.

A Multi-Layered Transport Hub
To transform the area into a high-capacity transit zone, the Bangalore Development Authority (BDA) decided to make more than one tunnel so it could handle heavy traffic volumes.
Authorities have designed a new bridge that will soon connect Blocks 5 and 6 of the Kempegowda Layout. It is located just 10 meters from the underpass.
The 11-kilometer stretch will feature 10 lanes in total. This includes six lanes for high speed traffic and four service lanes for local commuters.
Green Commuting: Responding to public requests, the authority is adding a cycle track and planting fruit and flower bearing trees to create a green canopy along the corridor.
Looking Toward the Future
The Major Arterial Road serves as a vital link for the upcoming Peripheral Ring Road Phase 2, which will eventually connect Hosur Road to the Mysuru highway. To prevent future gridlock, officials are working with traffic police to design the Challaghatta junction with advanced signaling and integrated service roads.
While 17 missing links in the service roads are still being paved, the government has already approved the acquisition of four additional acres to ensure the project meets its April deadline. Once finished, the road will provide a seamless, high speed bypass for thousands of daily motorists.
