The Bengaluru-Mysuru Expressway is a roughly 118 km, ten-lane (six-lane main carriageway plus four lanes of service roads) access-controlled highway on National Highway 275 (NH-275) that connects Bengaluru with Mysuru in Karnataka. The Bengaluru-Mysuru Expressway was built by the National Highways Authority of India (NHAI), was inaugurated in March 2023, and cut the travel time between the two cities to roughly 75 to 90 minutes in good conditions.
The Bengaluru-Mysuru Expressway matters because it links Karnataka’s capital and information technology hub with the state’s cultural and tourism capital, and it removed a slow, town-by-town journey that regularly took more than three hours. This explainer covers the route, the construction, the bypasses, the elevated and underpass sections, tolling, and the early teething problems.

What is the Bengaluru-Mysuru Expressway?
The Bengaluru-Mysuru Expressway is a controlled-access highway on NH-275 that carries fast traffic between Bengaluru and Mysuru without local crossings or direct roadside access. The main carriageway is meant for high-speed vehicles such as cars, buses and trucks, while slower local traffic uses separate service roads.
NH-275 is the long-standing national highway between Bengaluru and Mysuru that continues toward Kodagu and the Karnataka coast. Earlier, this highway ran through the centre of every town on the way and had mixed traffic and frequent bottlenecks. The Bengaluru-Mysuru Expressway upgraded the corridor into a six-lane main road for through traffic, with bypasses, so that the journey became fast and predictable.
Where does the Bengaluru-Mysuru Expressway run?
The Bengaluru-Mysuru Expressway runs from the NICE Road junction near Bengaluru to the Mysuru Ring Road, passing through the districts of Bengaluru Urban, Ramanagara and Mandya before reaching Mysuru. Along the way it passes close to Bidadi, Ramanagara, Channapatna, Maddur, Mandya and Srirangapatna.
The route crosses the Old Mysore plateau, a mostly flat agricultural belt known for sugarcane, silk, toys and the Cauvery river system. Entry and exit points allow traffic to join and leave at selected junctions, while the main carriageway remains free of at-grade crossings. Toll plazas are located near both ends of the route, close to Bengaluru and near the Mysuru side.
Who built the Bengaluru-Mysuru Expressway?
The National Highways Authority of India (NHAI), the national agency under the Ministry of Road Transport and Highways, built the Bengaluru-Mysuru Expressway through contractors who executed the work in several packages. NHAI planned the project as part of a larger programme to modernise the Bengaluru-Mysuru corridor.
The cost was reported at around eight thousand crore rupees, funded by NHAI. Construction started in the late 2010s, and was slowed by land acquisition, utility shifting and the pandemic, before the road was opened in stages and formally inaugurated in March 2023. The project is an example of the central government’s push for faster, access-controlled corridors between major city pairs.
- Owner and executor: National Highways Authority of India (NHAI).
- Ministry: Ministry of Road Transport and Highways.
- Highway number: NH-275.
- Delivery: multiple contract packages along the 118 km corridor.
Why was the Bengaluru-Mysuru Expressway built?
The Bengaluru-Mysuru Expressway was built because traffic between Bengaluru and Mysuru had outgrown the old highway, which was slow, congested and unsafe as it passed through towns and villages. Bengaluru is a global technology centre, and Mysuru is a heritage and tourism city with a large student and business population.
Thousands of commuters, tourists, students and freight vehicles used the old road daily, and weekend and festival traffic, especially during the Mysuru Dasara festival, frequently caused jams. A faster road was expected to boost tourism, support industry in the Old Mysore region and bring Mysuru closer to Bengaluru as a second economic centre. It also forms part of a broader plan for improved links between Bengaluru and the south of the state.
Why is the Bengaluru-Mysuru Expressway called ten-lane?
The Bengaluru-Mysuru Expressway is called ten-lane because it combines a six-lane main carriageway for through traffic with four lanes of service roads, two on each side, for local traffic. The ten-lane label therefore counts the service roads and does not mean that ten lanes are available to high-speed vehicles.
Separating local and through traffic is a core idea of the design. Slow vehicles, local buses and people travelling between nearby villages use service roads, while the main carriageway is reserved for fast traffic. Two-wheelers, three-wheelers, tractors and other slow vehicles are not permitted on the main carriageway.
| Component | Purpose |
|---|---|
| Six-lane main carriageway | High-speed through traffic between Bengaluru and Mysuru |
| Service roads (two on each side) | Local movement between villages and towns |
| Bypasses | Keep through traffic out of town centres |
| Underpasses and overpasses | Let local roads, people and animals cross safely |
| Elevated sections | Carry the expressway over towns and busy junctions |
Which towns does the Bengaluru-Mysuru Expressway bypass?
The Bengaluru-Mysuru Expressway bypasses several towns, most notably Ramanagara, Channapatna, Maddur and Mandya, so that long-distance traffic does not need to pass through their streets. Bypasses are among the main reasons the travel time dropped so sharply.
On the old highway, each of these towns was a bottleneck with traffic lights, markets, bus stops and pedestrians. Ramanagara is known for its rocky hills and silk, Channapatna for its wooden toys, Maddur for its snack called Maddur vada and Mandya for sugarcane and agriculture. After the bypasses opened, drivers on the main carriageway no longer pass through these towns, and local officials and traders have been working on ways to ensure the towns still benefit from the traffic.
What elevated sections and underpasses does the Bengaluru-Mysuru Expressway have?
The Bengaluru-Mysuru Expressway has elevated stretches near towns such as Ramanagara and Channapatna, along with numerous bridges, flyovers, underpasses and railway overbridges. These structures allow the expressway to cross rivers, railway lines and local roads without level crossings.
Underpasses are provided for vehicles, cattle and people to cross the expressway, which is important in a region with many villages close to the alignment. Some underpasses were affected by waterlogging during heavy rain in the first monsoon after opening, which led to repairs and drainage improvements. Modern features such as fencing, signage, cameras and emergency lanes are also part of the design.
How does tolling work on the Bengaluru-Mysuru Expressway?
Tolling on the Bengaluru-Mysuru Expressway is collected by NHAI at plazas near both ends of the route, using FASTag electronic payment, with rates set by vehicle class. Toll collection began shortly after the inauguration, in spring 2023, and rates have been revised since.
Toll charges on the expressway attracted public debate because they were higher than on the old highway, although travel time and fuel use are lower. Local residents who use the service roads do not pay toll for those roads. Because rates are revised periodically, travellers should check the latest notified toll schedule before relying on any specific number.
What problems did the Bengaluru-Mysuru Expressway face after opening?
The Bengaluru-Mysuru Expressway faced three main problems after opening: a high number of accidents, waterlogging during heavy monsoon rain, and economic disruption in bypassed towns. These problems were reported widely in the first months after the road went into full use.
Accidents were often attributed to overspeeding, wrong-side driving, sudden lane changes, tyre bursts and slow vehicles entering the main carriageway. Authorities responded with speed cameras, automated number plate recognition, an intelligent traffic management system, patrol teams, tighter rules for slow vehicles and awareness campaigns. Drainage was improved at low-lying spots, and officials worked on fixing design gaps such as unprotected crossings.
Which safety rules apply on the main carriageway?
The main safety rules are a speed limit of about 100 km/h for cars, a ban on two-wheelers, three-wheelers, tractors and other slow vehicles, lane discipline and no stopping except in emergencies. Cameras record violations, and penalties are applied through electronic challans.
How has the Bengaluru-Mysuru Expressway changed travel and the economy?
The Bengaluru-Mysuru Expressway has changed travel by cutting the Bengaluru-Mysuru journey to roughly 75 to 90 minutes, turning day trips and weekend visits into easy options. Tourism, hospitality and retail in Mysuru have benefited from faster access to Bengaluru’s large population.
Business effects are mixed. Mysuru’s technology and manufacturing sectors gain from better connectivity, and commuters can consider living in one city and working in the other. In contrast, small eateries, roadside shops and petrol pumps in bypassed towns lost passing trade, and some families have had to adjust. Over time, interchanges, rest areas and local promotion may help redistribute benefits.
What is the future outlook for the Bengaluru-Mysuru Expressway?
The future outlook for the Bengaluru-Mysuru Expressway depends on continued safety improvements, better integration with feeder roads and the possible extension of high-speed links toward Kodagu and the coast. Planners also discuss rail, suburban and airport connectivity to complement the road.
Traffic is expected to rise as the region develops, which may require further capacity, strong enforcement and good maintenance. The Bengaluru-Mysuru Expressway will probably remain the central road link between the two cities, and its performance will be a reference point for other Indian city-pair corridors.
How does the Bengaluru-Mysuru Expressway compare with the old highway?
The Bengaluru-Mysuru Expressway differs from the old NH-275 route in that through traffic now stays on a six-lane road away from town centres, whereas the old highway mixed long-distance and local vehicles on two or four lanes. This separation is the main reason for the large drop in travel time and for the improvement in fuel efficiency on the corridor.
The old road is still used by local traffic and by those who prefer to avoid toll, and in places it functions as the service road. Journey times on the old route remain much longer, particularly at peak hours, and road conditions there are generally less uniform. For most long-distance travellers, the expressway has become the default choice, while the older alignment now acts as a local connector for the towns along the way.
What should travellers keep in mind?
Travellers on the Bengaluru-Mysuru Expressway should plan fuel stops and rest breaks in advance, because facilities on the main carriageway are limited compared with the service roads and nearby towns. Checking tyre pressure before departure, keeping to the left lane when driving slowly and avoiding sudden lane changes are the simplest ways to reduce risk.
It also helps to carry a valid FASTag, to avoid stopping on the shoulder except in an emergency, and to keep the highway helpline number handy. Early morning and late evening hours can bring low visibility and fog patches in cooler months, so extra caution is advisable at those times. Weekend and festival periods, especially around Dasara in Mysuru, tend to bring heavier traffic.
Bottom Line
The Bengaluru-Mysuru Expressway is a roughly 118 km NHAI-built corridor on NH-275 that shrank the journey between Karnataka’s tech capital and its heritage capital to about an hour and a half. Early accidents and local economic effects have prompted fixes, and its long-term success will rest on safe operation and balanced regional benefits.
