According to officials, the Major Arterial Road could witness bottlenecks because a 300-foot-wide road at either end converges into roads that are at least four times narrower.

The main carriageway of Bengaluru’s Major Arterial Road (MAR), the city’s widest road with a width of 320 feet, is set to be inaugurated by the end of June. The MAR runs parallel to NICE Road, passes through Nadaprabhu Kempegowda Layout (NPKL) and spans 10.76 km.
Earlier, The Hindu reported the possibility of bottlenecks at the ends of the road. Now, the Bangalore Development Authority (BDA) and Bengaluru Traffic Police (BTP) have planned to install traffic signals at both ends to address the issue, after considering diverting traffic through the interior roads of NPKL. However, this will be a temporary measure as the BDA is planning an underpass and cloverleaf for smooth movement.
High volume
According to sources, although some vehicles can be diverted through other roads, the volume of traffic at the connecting junctions is still expected to be high, making the installation of signals inevitable.
“The actual volume of vehicles can only be assessed once the stretch becomes fully operational and more people start using it. However, preliminary projections suggest the need for traffic signals,” a traffic official said.
Reason behind the problems
According to the official, the primary reason for bottlenecks is that a 300-foot-wide road at either end converges into roads that are at least four times narrower.
Moreover, the MAR connects Mysuru Road with Magadi Road. Magadi Road already experiences heavy traffic, particularly during weekends, and BTP officials say congestion at the MAR convergence point on Magadi Road is inevitable.
On the other hand, the MAR will not directly connect to the Bengaluru–Mysuru Access Controlled Highway. While the MAR ends near Challaghatta Metro Station, the highway begins a few kilometres earlier. As a result, commuters from the northwestern parts of the city who wish to access the highway will have to travel a few extra kilometres.
“When the road was planned, provisions could have been made for more connecting roads within NPKL, creating links to different points so that commuters would have multiple route options. Now, the BDA is exploring whether interior roads can be connected to different ends,” a source said.
According to BDA sources, the road was planned as far back as 2017, and the extent of the current issues and shortcomings could not have been foreseen at the time.
Great for connectivity
Despite the design flaws, the MAR provides a significant connectivity link between Mysuru Road (National Highway) and Magadi Road (State Highway). The 10.76-km stretch will also form part of the 54-km Peripheral Ring Road-1 (PRR), which will connect Hosur Road and Tumakuru Road via Bannerghatta Road, Hosur Road, and Magadi Road.
Viral MAR collapse video clarified
A purported video that went viral on social media showed a portion of the MAR caving in following heavy rainfall on Saturday. The BDA identified the issue and rectified it within two days. The BJP also took to social media to criticise the Congress government over the allegedly shoddy work.
Reacting to the issue, P. Manivannan, Commissioner of BDA, told The Hindu that in the run-up to the inauguration, certain social media handles and sections of the media have circulated videos showing damaged portions of a service road, claiming that the MAR itself has collapsed before inauguration. “This creates the false impression that the road being inaugurated is structurally defective. This is factually incorrect,” he said.
Another BDA source said that the stretch due for inauguration is the main carriageway, and the service roads won’t be inaugurated as works are yet to be completed in those stretches.
The sinkhole shown in the video is in the service lane, the official said.
