Mysuru: Twelve accident-prone black spots along the 119-km Bengaluru-Mysuru National Highway-275 recorded 169 accidents and 97 deaths between 2023 and 2025, according to data from the National Highways Authority of India (NHAI).
The identified locations are spread across the Bengaluru-Mysuru highway, with 10 black spots falling in Mandya district and two in the Bengaluru South section, which was earlier part of Ramanagara district.
The data highlights the continuing road-safety challenges along the busy highway despite a decline in the overall number of accidents over the three-year period.
Agralinganadoddi-Thylur records most accidents
Among the identified locations, Agralinganadoddi-Thylur recorded the highest number of accidents.
NHAI data shows that the black spot witnessed 56 accidents and 22 deaths between 2023 and 2025. The location accounted for nearly one-third of all accidents recorded across the 12 identified black spots.
Maddur Exit was another major accident-prone location. It recorded 25 accidents during the period, resulting in 21 deaths.
The high fatality figure at Maddur Exit indicates that the severity of crashes remains a concern even at locations where the number of accidents is lower than some other black spots.
Kempanhalli sees high fatality rate
Kempanhalli, near SK Group of Companies and under the Ramanagara Traffic Police Station limits, recorded 11 accidents and 13 deaths between 2023 and 2025.
Although the number of accidents was considerably lower than at Agralinganadoddi-Thylur, the number of fatalities was relatively high.
Another significant location was Gejjalagere in Mandya district, where 18 accidents resulted in nine deaths during the same period.
The data also points to Jayapura Gate-Kunigal Road-Bilagumbha Junction, where 17 accidents claimed 22 lives.
These figures show that accident frequency alone does not provide a complete picture of road safety, as some locations have recorded fewer crashes but a higher proportion of fatalities.
2023 was the worst year
The NHAI figures show a substantial decline in accidents after 2023.
In 2023, the 12 black spots collectively recorded 90 accidents, resulting in 55 deaths. The number fell to 43 accidents and 21 deaths in 2024.
In 2025, accidents declined further to 36, the lowest figure among the three years. However, fatalities remained at 21.
Nearly 53% of the accidents and 57% of the deaths recorded at the identified black spots during the three-year period occurred in 2023.
While the reduction in accidents is significant, the unchanged number of fatalities between 2024 and 2025 indicates that serious crashes continue to occur at some locations.
NHAI introduces road safety measures
Several road safety measures have been implemented along the Bengaluru-Mysuru highway, including at identified black spots.
According to NHAI, these measures include speed-limit boards, lane-discipline signs, traffic regulatory boards and information signboards designed to provide motorists with advance warnings.
Automatic Number Plate Recognition (ANPR) cameras have also been installed to monitor traffic and assist with speed enforcement.
Intelligent Traffic Management Systems (ITMS) and Route Patrolling Vehicles (RPVs) are among the other measures being used on the highway.
The objective is to improve lane discipline, regulate vehicle speeds and provide motorists with better information about road conditions and upcoming junctions.
24 foot overbridges installed
Pedestrian safety has also been addressed through the installation of foot overbridges.
NHAI has provided 24 foot overbridges along the Bengaluru-Mysuru highway at a cost of Rs 34.55 crore. Additional road signboards have been installed at a cost of Rs 4.70 crore, according to the report.
The foot overbridges are intended to help pedestrians cross busy sections of the highway without directly interacting with fast-moving traffic.
The additional signage is aimed at improving visibility and giving drivers advance information about speed restrictions, junctions and other potential hazards.
Calls for better rest facilities
Bangalore Rural MP Dr C.N. Manjunath has sought further information from NHAI regarding the identified black spots and the safety measures being implemented.
He has also highlighted the need for proper rest areas for travellers and long-distance drivers.
According to Manjunath, adequate rest facilities could help reduce driver fatigue, which can contribute to road accidents.
Rest areas can provide long-distance drivers with designated locations to take breaks rather than continuing to drive for extended periods without adequate rest.
The issue is particularly relevant on the Bengaluru-Mysuru highway because of the substantial movement of buses, cars, commercial vehicles and other traffic between the two cities.
12 black spots identified
The 12 accident-prone locations identified along the highway are:
- Agralinganadoddi-Thylur
- Maddur Exit
- Kempanhalli near SK Group of Companies
- Gejjalagere
- Thubinakere
- Puttapanadoddi near Buildcon Ltd. RO Office
- K. Shettihalli at the Srirangapatna entry and exit
- Mandya Exit at Guthalu
- Niddaghatta Entry Junction
- Jayapura Gate-Kunigal Road-Bilagumbha Junction
- Kolluru near Niddaghatta
- Halebudanuru
The locations cover stretches across Mandya and the Bengaluru South section of the highway.
Road safety remains a priority
The Bengaluru-Mysuru highway is one of Karnataka’s important road corridors, connecting the State capital with Mysuru and several towns and villages along the route.
The reduction in accidents recorded at the identified black spots between 2023 and 2025 coincides with the implementation of several technology-based monitoring and enforcement measures.
However, the 97 deaths recorded over three years demonstrate the potential consequences of crashes at vulnerable locations.
Continued monitoring of black spots, enforcement of speed and lane rules, improved signage, pedestrian facilities and adequate rest areas could form part of ongoing road-safety efforts along the corridor.
Conclusion
The 12 identified black spots on the Bengaluru-Mysuru Highway recorded 169 accidents and 97 deaths between 2023 and 2025. While accidents declined sharply from 90 in 2023 to 36 in 2025, fatalities remained at 21 in both 2024 and 2025.
NHAI has implemented measures including ANPR cameras, traffic management systems, signage, route patrol vehicles and foot overbridges. Further monitoring and road-safety interventions will remain important to reduce the severity of crashes along the highway.
