The G.D. Naidu Elevated Expressway, earlier known as the Avinashi Road Flyover, is one of the biggest infrastructure projects ever built in Coimbatore. Stretching across 10.1 km, the elevated corridor connects Goldwins near the airport side to Uppilipalayam, transforming one of the city’s most crowded roads into a faster and smoother route.
The project has become an important symbol of Coimbatore’s growth, not only because it is Tamil Nadu’s longest flyover, but also because it significantly reduces travel time and improves connectivity across the city.
Overview of the Project
The G.D. Naidu Elevated Expressway is built along Avinashi Road, one of Coimbatore’s busiest arterial roads. Before the flyover was constructed, this road often experienced severe traffic congestion, especially during office hours, school timings, and airport traffic.
The elevated corridor now bypasses most of these traffic bottlenecks and allows uninterrupted travel above the road.

The corridor is currently the longest flyover in Tamil Nadu and among the longest elevated roads in India. It is also considered the second-longest elevated corridor in the country after the P. V. Narasimha Rao Expressway.
Why the Flyover Was Needed
Avinashi Road is one of Coimbatore’s most important roads. It connects:
- Coimbatore city centre
- Peelamedu
- Nava India
- Hope College
- Lakshmi Mills
- Airport area
- Chinniyampalayam and eastern suburbs
Before the G.D. Naidu Elevated Expressway, commuters had to cross around 12 busy intersections. During peak hours, a journey of 10 km could easily take 40 to 45 minutes.
The elevated corridor was planned to solve these problems by:
- Reducing congestion
- Improving airport connectivity
- Reducing fuel wastage
- Lowering travel time
- Supporting future urban growth in Coimbatore
The project was first proposed in 2019, approved in 2020, and completed after nearly five years of construction.
Route and Connectivity
The flyover begins near Goldwins junction and ends at Uppilipalayam. Along the way, it crosses several important parts of Coimbatore.
Major Areas Covered
- Goldwins
- Airport region
- Peelamedu
- Nava India
- Hope College
- Lakshmi Mills
- Uppilipalayam
The flyover bypasses around 12 major traffic intersections, allowing vehicles to travel continuously without stopping at signals.
Ramps and Access Points
The project includes multiple up-ramps and down-ramps to help motorists enter and exit the flyover.
Important ramp locations include:
- Anna Silai
- Nava India
- Peelamedu
- Airport side
There are eight ramps in total across four key junctions. One ramp near Anna Silai remained temporarily incomplete because of a legal issue, while the remaining ramps were opened to the public.
Engineering and Construction Features
The G.D. Naidu Elevated Expressway is not just long; it is also technically advanced.
The corridor was built using PSC Segmental Construction (Post-Tensioned Structural Concrete), a modern construction method used for large elevated roads and metro projects. This technique improves strength, durability, and speed of construction.
Major Technical Features
- 304 supporting pillars
- Four-lane elevated roadway
- Six-lane widened surface road below in certain sections
- Roller crash barriers for improved safety
- Modern expansion joints
- Advanced drainage system
- Energy-efficient LED lighting
- Landscaping and decorative median planting
The flyover also includes bougainvillea and golden cypress plants placed along the median. A drip irrigation system with 13 borewells was installed to maintain the greenery.
Travel Time Reduced Dramatically
One of the biggest benefits of the flyover is the reduction in travel time.
Earlier, traveling from Goldwins to Uppilipalayam through Avinashi Road could take between 30 and 45 minutes, especially during rush hours.
Now, motorists can cover the same distance in about 10 minutes.
The highways department has fixed a speed limit of 60 km/h on the elevated corridor.
For people traveling to the airport, the change is even more noticeable. Residents from central Coimbatore can now reach the airport much faster without waiting at multiple signals.
Impact on Coimbatore
The expressway is expected to change the traffic pattern of Coimbatore for many years.
Major Benefits
- Less traffic congestion on Avinashi Road
- Faster airport access
- Reduced fuel consumption
- Lower pollution due to less idling at signals
- Better connectivity between eastern and central Coimbatore
- Increased property value near the corridor
- Faster movement for emergency vehicles and public transport
The flyover also improves access to important commercial and residential areas around Peelamedu, Nava India, and Hope College.
Experts believe that the project will support Coimbatore’s future growth, especially as the city continues to expand toward the eastern side.
Why It Is Named After G.D. Naidu
The flyover is named after G. D. Naidu, one of Coimbatore’s most respected personalities.
Known as the “Edison of India,” G.D. Naidu was an inventor, engineer, and industrialist who contributed greatly to technology, transport, and manufacturing.
He was associated with:
- Early electric motor development in India
- Automobile and mechanical innovation
- Industrial growth in Coimbatore
- Technical education and engineering research
Because of his contributions, the government decided to name the expressway after him.
G.D. Naidu Elevated Expressway
Although many people welcomed the name, there was also some debate.
Some critics argued that the word “Naidu” can be seen as a caste-based title. This became controversial because the Tamil Nadu government had recently announced a policy to remove caste-based names from public places and infrastructure.
Political leaders and members of the public questioned whether the name matched that policy. However, government officials defended the decision, saying that the expressway was named after a famous historical personality rather than for caste reasons.
Comparison With Other Major Flyovers in India
| Flyover / Elevated Corridor | City | Length |
|---|---|---|
| P. V. Narasimha Rao Expressway | Hyderabad | 11.6 km |
| G.D. Naidu Elevated Expressway | Coimbatore | 10.1 km |
| Hebbal Flyover | Bengaluru | Approx. 5.3 km |
| Bandra-Worli Sea Link | Mumbai | Approx. 5.6 km |
The Coimbatore corridor now stands among India’s major urban transport projects.
