Bangalore Satellite Town Ring Road [STRR] – NHAI – Maps & Information

The Bangalore STRR (Satellite Town Ring Road) is a 280.8 km access-controlled highway project designed to decongest Bengaluru by diverting inter-city traffic away from the urban core. Developed by the National Highways Authority of India (NHAI), the STRR Bangalore project aims to improve connectivity between satellite towns and major national highways surrounding Bengaluru.

Once completed, the Bangalore STRR will significantly reduce traffic congestion, shorten travel time, and promote industrial and real estate growth across peripheral regions.

What is STRR Bangalore?

The STRR Bangalore is a 4-lane access-controlled expressway (expandable to 6 lanes) that forms a large outer ring around Bengaluru, connecting key national highways without requiring vehicles to enter city limits.

Key Highlights:

Total Length: 280.8 km

Developed by: NHAI

Type: Access-controlled highway

Configuration: 4-lane (expandable to 6-lane)

Purpose: Divert inter-city & heavy vehicle traffic

The project is particularly important for freight vehicles, airport connectivity, and logistics movement.

STRR Bangalore Map & Route Alignment

The STRR Bangalore map shows a complete outer connectivity corridor linking northern, eastern, southern, and western satellite towns.

Major Highways Connected by STRR:

• NH 44 (Hyderabad Highway)

• NH 48 (Mumbai Highway)

• NH 75 (Mangaluru Highway)

• NH 209 (Kanakapura Corridor)

• Airport access corridor near Kempegowda International Airport

  
  

The STRR road map clearly shows how the corridor bypasses city congestion and creates seamless inter-state movement.

Satellite Towns Covered Under Bangalore STRR

The STRR ring road map connects 12 major satellite towns in Karnataka:

S.No.	Major Satellite Town	State
1	Dobbasapete	Karnataka
2	Doddaballapura	Karnataka
3	Devanahalli	Karnataka
4	Sulibele	Karnataka
5	Hoskote	Karnataka
6	Sarjapura	Karnataka
7	Attibele	Karnataka
8	Anekal	Karnataka
9	Tattekere	Karnataka
10	Kanakapura	Karnataka
11	Ramanagara	Karnataka
12	Magadi	Karnataka

These towns are expected to witness major economic growth once STRR becomes fully operational.

Phase-wise Construction Status of STRR Bangalore

The Bangalore STRR project is divided into three major phases:

Phase 1 – 82 km

STRR Banglore map spans a distance of 82 km from Dobbspet and is nearing completion and is expected to open soon. This stretch is critical in connecting the northern and southern parts of the city and will significantly reduce travel time for commuters.

Phase 2 – 56 km

Covering a distance of 56 km, has been held up due to environmental concerns. This phase requires careful planning and approval to ensure that the construction does not have any adverse impact on the surrounding environment. The authorities are working closely with environmental experts to come up with a sustainable plan that will mitigate any potential harm to the flora and fauna in the area.

Phase 3 – 142.8 km

The Bangalore STRR, spanning a distance of 142.8 km, will complete the entire ring road, connecting the remaining towns. This phase is crucial in providing better connectivity to the peripheral areas of the city and facilitating the growth of satellite towns. The completion of the Bangalore STRR will also reduce the burden on the existing road network and ease traffic congestion in the city.

Technical Features of STRR Bangalore

Key specifications include:

• 4-lane access-controlled highway

• Provision for future 6-lane expansion

• Grade-separated interchanges

• Flyovers and underpasses

• Service roads for local traffic

• Truck lay-bys and rest areas

• Toll plazas at strategic locations

These features make STRR Bangalore a long-term mobility solution.

Benefits of Bangalore STRR

1. Reduced Traffic Congestion

Heavy vehicles and inter-city traffic will bypass Bengaluru city roads.

2. Faster Airport Connectivity

Travel time between Hoskote and Kempegowda Airport could reduce significantly.

3. Boost to Satellite Town Development

STRR will accelerate industrial parks, logistics hubs, and residential development in peripheral areas.

4. Economic Growth

Improved freight movement enhances regional trade efficiency.

5. Real Estate Appreciation

Areas like Devanahalli, Hoskote, and Sarjapura are expected to benefit from improved connectivity.

STRR vs Outer Ring Road (ORR)

Unlike the city-level Outer Ring Road (ORR), the Bangalore STRR operates as a much larger outer corridor meant primarily for inter-city and freight traffic.

While ORR handles urban movement, STRR is designed to manage highway-to-highway transitions.

This distinction is important for understanding long-term traffic planning in Bengaluru.

Expected Impact on Bengaluru’s Infrastructure

The STRR Bangalore project will:

• Reduce pressure on city roads

• Improve logistics efficiency

• Encourage industrial corridors

• Strengthen airport connectivity

• Promote decentralized urban expansion

It positions Bengaluru for sustainable long-term growth.

Conclusion

The Bangalore STRR is one of the most significant infrastructure projects shaping the future of regional mobility around Bengaluru. By connecting 12 major satellite towns and linking multiple national highways, the STRR Bangalore map reflects a transformative shift in traffic management and economic planning.

Once fully operational, the STRR ring road map will redefine connectivity, reduce congestion, and unlock new development corridors across Karnataka.
