Route Realignment, Major Exits & Interchanges
The Bengaluru-Mysore Expressway spans 119 kilometres along National Highway 275 (NH-275), establishing a modern high-speed transportation spine across the southern interior of Karnataka. Beginning at Panchamukhi Ganesha Temple near the Kumbalgodu flyover and NICE Road Junction (Km 0) in Bengaluru South, the expressway traverses rural and peri-urban landscapes across Bengaluru Urban, Ramanagara, Mandya, and Mysuru districts before terminating at the Columbia Asia Junction on the Mysuru Ring Road (Km 119). To streamline construction and project management, the National Highways Authority of India (NHAI) split the project into two distinct operational packages: Package 1 spanning 56.2 km from Bengaluru to Nidaghatta, and Package 2 covering 61.1 km from Nidaghatta to Mysuru.
A critical engineering objective of the expressway project was isolating high-speed inter-city express traffic from slow-moving local township vehicles. This was accomplished by constructing five massive grade-separated bypasses around historically congested urban bottlenecks that previously plagued the old NH-275 route. The key bypasses include the 7 km Bidadi bypass, the continuous 22 km Ramanagara-Channapatna dual-town bypass, the 7 km Maddur bypass, the 10 km Mandya bypass, and the 7 km Srirangapatna historic town bypass. By redirecting long-distance vehicular flow around these busy urban areas, the express lanes eliminate gridlock and prevent local traffic interference.
For drivers needing to access intermediate commercial hubs or tourist destinations, the corridor incorporates strategically designed exit interchanges equipped with acceleration and deceleration slip lanes. Major exit points include the Kumbalgodu/NICE Road interchange (Km 0) for Outer Ring Road traffic, Bidadi exit (Km 25) serving local industrial complexes and Big Banyan Tree (Ramohalli), Ramanagara exit (Km 45) providing access to silk processing centres and eco-tourism rock climbing sites, Channapatna exit (Km 65) connecting to the world-famous wooden toy crafting clusters, Maddur exit (Km 80) serving agricultural markets and famous food stops, Mandya exit (Km 95) serving the regional sugar manufacturing hub, Srirangapatna exit (Km 110) connecting to Tipu Sultan heritage monuments and Ranganathittu Bird Sanctuary, and the Mysuru Ring Road exit (Km 119) for seamless entry into Mysuru city centre, Chamundi Hill, or onward journeys toward Coorg, Kerala, and Wayanad.
Engineering Marvels, Infrastructure Design & Safety
The civil engineering architecture of the Bengaluru-Mysore Expressway represents a world-class standard in Indian highway design. The cross-sectional profile of the corridor features a 10-lane multi-modal configuration comprising a 6-lane access-controlled central carriageway (3 lanes in each direction) separated by a central median, flanked on both outer sides by 2-lane asphalt service roads. The 6-lane main carriageway is strictly reserved for high-speed motorized transport, while the service roads accommodate local two-wheelers, three-wheelers, agricultural tractors, and intra-town short trips. This design eliminates friction between differing vehicle categories and elevates overall corridor safety.
Overcoming geographical obstacles along the river basins required significant structural engineering interventions. The 119 km highway features 8 kilometres of elevated viaduct corridors, 64 pedestrian and vehicle underpasses (VUPs/PUPs) to allow local communities to cross safely beneath the express lanes, 11 overpasses, 4 major river bridges spanning the Cauvery, Shimsha, Arkavathi, and Lokapavani rivers, 42 minor bridges, and 240 reinforced concrete box culverts for efficient hydrological drainage. The elevated viaduct at Bidadi and the long river bridge across the Cauvery at Srirangapatna highlight the project's structural achievements, ensuring structural stability during monsoon flood conditions.
Safety engineering has been prioritized throughout the expressway's construction. Continuous metal W-beam crash barriers and reinforced concrete jersey barriers line the perimeter of the access-controlled main lanes, preventing stray livestock, dogs, or unauthorized pedestrians from entering the high-speed ROW (Right of Way). Furthermore, the corridor is equipped with an Advanced Traffic Management System (ATMS). This includes high-definition CCTV surveillance cameras stationed every 1 kilometre, doppler radar speed guns for automated speeding detection, dynamic Variable Message Signboards (VMS) providing real-time weather and traffic alerts, automated incident detection sensors, and solar-powered emergency call boxes linked to the central highway operational command centre.
Toll Rates, Plazas, FASTag & Satellite Tolling 2026
Tolling operations on the Bengaluru-Mysore Expressway are structured around an open-and-closed hybrid tolling methodology managed electronically through FASTag technology. Mainline toll collection is conducted at two primary toll plaza locations: the Sheshagirihalli Toll Plaza near Bidadi (handling Package 1 traffic) and the Gananguru Toll Plaza near Srirangapatna (handling Package 2 traffic). Additional entry and exit toll booths operate at intermediate interchanges to ensure drivers pay tolls proportional to the distance travelled along the corridor.
| Vehicle Class | Package 1 Toll (Bidadi) | Package 2 Toll (Gananguru) | Full Length Toll (Single Trip) | Full Length Return Pass (24 Hours) |
|---|---|---|---|---|
| Cars / Jeeps / Vans (M1) | ₹170 | ₹155 | ₹325 | ₹490 |
| Light Commercial Vehicles (LCV) | ₹275 | ₹250 | ₹525 | ₹790 |
| Buses / 2-Axle Heavy Trucks | ₹575 | ₹525 | ₹1,100 | ₹1,650 |
| 3-Axle Commercial Vehicles | ₹625 | ₹570 | ₹1,195 | ₹1,795 |
| Heavy Construction Equipment (4-6 Axle) | ₹900 | ₹825 | ₹1,725 | ₹2,590 |
In accordance with MoRTH mandates, toll collection across all lanes operates 100% digitally through FASTag 2.0 RFID readers. Non-FASTag vehicles or vehicles with insufficient balance entering FASTag lanes are levied a 100% penalty fee equal to double the standard toll rate. To streamline traffic flow further, NHAI initiated a pilot program testing Global Navigation Satellite System (GNSS) satellite-based distance tolling along the expressway. Utilizing high-precision Virtual Toll Gates and satellite tracking linked with Automatic Number Plate Recognition (ANPR) cameras mounted on gantry structures, GNSS technology enables registered vehicles to travel at full speed without stopping at physical toll barriers. The system automatically calculates distance travelled down to the exact metre and deducts the appropriate toll directly from the owner's linked bank account or digital wallet.
Government Framework & NHAI Oversight
The Bengaluru-Mysore Expressway was conceptualized, funded, and executed under the strategic guidance of the Ministry of Road Transport and Highways (MoRTH), headed by Union Minister Nitin Gadkari, with the National Highways Authority of India (NHAI) acting as the executing agency. The project was implemented on a Hybrid Annuity Model (HAM) contractual framework, where the central government provided 40% of the project capital during construction while the private concessionaire, Dilip Buildcon Limited (DBL), raised the remaining 60% equity and debt, recovering investments through bi-annual annuity payments over a 15-year operational period. Prime Minister Narendra Modi officially dedicated the expressway to the nation in March 2023, marking a major milestone in India's Bharatmala Pariyojana program.
To uphold safety standards and protect high-speed passenger traffic, NHAI issued formal regulatory notifications setting maximum operational speed limits and restricting certain low-speed vehicle categories. The official speed limit for passenger cars and light vehicles (M1 category) is fixed at 100 km/h on the main carriageway, while commercial goods carriers and heavy buses are capped at 80 km/h. Speed enforcement is actively managed by automated radar systems and police highway patrol units using mobile lidar speed guns.
Crucially, NHAI issued an explicit ban prohibiting non-motorised vehicles, agricultural tractors, two-wheelers (motorcycles and scooters), three-wheelers (auto-rickshaws), and quadricycles from using the main 6-lane access-controlled carriageway. These low-speed vehicle classes are legally required to use the 2-lane service roads running parallel on either side of the highway. This policy was enacted following safety audits which demonstrated that speed differentials between fast-moving cars (travelling at 100 km/h) and slow-moving two/three-wheelers were the primary cause of fatal rear-end collisions during the initial trial phase. Enforcement of this vehicle restriction has significantly reduced accidents and maintained high average speeds along the main corridor.
Expressway vs Legacy NH-275 Comparison
Prior to the completion of the 10-lane access-controlled expressway, inter-city road travel between Bengaluru and Mysuru relied on the old, un-divided 4-lane State Highway / NH-275 route. The legacy highway suffered from severe urban congestion, frequent traffic signals, uncontrolled roadside encroachments, and dangerous speed variations caused by agricultural vehicles and pedestrians crossing through populated towns. The table below illustrates the technical, operational, and performance parameters contrasting the new expressway with the old legacy highway route.
| Parameter / Feature | New Bengaluru-Mysore Expressway (NH-275) | Old Legacy Highway Route (Pre-2023) |
|---|---|---|
| Total Distance | 119 km (Direct, bypass-driven alignment) | 135-150 km (Through town centres) |
| Average Travel Time | 90 minutes (1.5 hours) | 180 to 240 minutes (3 to 4 hours) |
| Total Lane Configuration | 10 Lanes (6 Access-Controlled + 4 Service Lanes) | 4 Lanes (Uncontrolled, mixed traffic) |
| Design / Posted Speed Limit | 100 km/h (Cars) / 80 km/h (Trucks) | 50 km/h to 80 km/h (Frequently reduced in towns) |
| Urban Bottlenecks / Bypasses | 5 Grade-Separated Bypasses (Zero town signals) | Direct passing through 5 major crowded towns |
| Access Control & Fencing | Fully fenced with W-beam & concrete barriers | Uncontrolled entry from all cross-roads |
| Safety Infrastructure | ATMS, 24/7 CCTV, Speed Radars, Underpasses | Basic signage, minimal surveillance |
| Fuel Consumption (Car Round Trip) | Saves approx. 3.0 to 4.0 litres of fuel | High fuel burn due to stop-and-go traffic |
The transformation delivered by the new corridor extends far beyond simple time savings. By eliminating stop-and-go driving through congested towns like Mandya and Ramanagara, vehicles operate at consistent, fuel-efficient cruise speeds. Studies conducted by transport logistics institutes reveal that commuters driving a standard petrol or diesel sedan save between 3 and 4 litres of fuel per round trip compared to the legacy route. Furthermore, the dramatic reduction in braking and acceleration cycles significantly decreases vehicle mechanical wear and tear, brake pad erosion, and carbon emissions per trip, yielding substantial environmental and economic dividends for regional transport operators.

The Bengaluru-Mysore Expressway forms a cornerstone of Karnataka's master plan for integrated regional mobility and infrastructure expansion. Future developments aim to extend this high-speed arterial connectivity across adjacent district highways and port corridors, cementing its role as South India's premier transport artery.
A key upcoming project linked to the expressway is the 4-lane Mysuru-Kushalnagar Highway expansion project (NH-275 extension). Spanning 93 kilometres from Mysuru Ring Road to Kushalnagar, this project will extend high-speed access directly into the heart of the Kodagu (Coorg) coffee-growing and eco-tourism region. Furthermore, the expressway integrates seamlessly with the ongoing construction of the Bengaluru Satellite Town Ring Road (STRR / NH-948A) and the proposed Peripheral Ring Road (PRR). These ring roads will allow freight traffic travelling from Chennai, Hyderabad, or Tumakuru to bypass Bengaluru urban traffic entirely before entering the Mysuru expressway corridor.
To enhance environmental sustainability and smart highway management, NHAI is implementing green infrastructure upgrades along the expressway. Thousands of native tree saplings and flowering shrubs have been planted along the central median and embankment slopes to absorb carbon emissions and prevent soil erosion. Additionally, plans are underway to install solar panel canopies over major toll plaza structures and service road interchanges, generating clean renewable power to fuel highway lighting systems, digital signage, and EV charging stations across the network.
In conclusion, the Bengaluru-Mysore Expressway stands as a benchmark achievement in India's modern infrastructure transformation. By combining 10-lane capacity, strict access control, advanced safety technology, and smart tolling, the project has successfully reduced travel times, enhanced road safety, and unlocked vast economic potential across Karnataka.
