Velachery Bypass Road is a busy urban corridor in South Chennai and is commonly known as the 100 Feet Bypass Road. Tamil Nadu Highways records identify it as SH-48C, with a length of about 1.9 km. The road runs through the Velachery residential and commercial belt and connects with the Vijayanagar Bus Terminus area, Velachery Main Road, Taramani Link Road and the wider Inner Ring Road network.
Unlike a highway bypass outside a city, Velachery Bypass Road now functions as a fully developed city arterial road. Shops, restaurants, banks, apartments and daily-use services line much of the corridor, while thousands of commuters use it to reach Velachery MRTS, Taramani, Guindy, Pallikaranai, Medavakkam and Tambaram-side roads. The road is also important for current transport planning because the Velachery-St Thomas Mount MRTS extension opened in 2026, while a proposed major flyover in the Velachery-Guru Nanak College corridor has been put on hold pending funding.

Where Is Velachery Bypass Road Located?
Velachery Bypass Road lies in the central Velachery area of South Chennai. Greater Chennai Corporation records use the name ‘Velachery Bypass 100′ Road’ and describe the road along the Vijayanagar side, while Tamil Nadu Highways lists Velachery Bypass Road as SH-48C.
Vijayanagar Bus Terminus is the most useful landmark for the road. From this junction, traffic can move towards Velachery Main Road, the MRTS station, Taramani Link Road and roads leading to Pallikaranai, Madipakkam and other southern neighbourhoods.
Connectivity of Velachery Bypass Road
The road works as a cross-connection inside South Chennai rather than a long-distance bypass. It is useful for commuters moving between Velachery’s residential areas and major employment or transport corridors around Guindy, Taramani, Perungudi, Pallikaranai and Tambaram.
Vijayanagar Junction and Velachery Main Road
Vijayanagar Junction is the key traffic point on the bypass. The junction handles buses, autos, two-wheelers and cars moving between 100 Feet Bypass Road, Velachery-Tambaram Main Road and Taramani Link Road.
Two flyover arms already help distribute traffic around Vijayanagar. One connects the Velachery Bypass side with the Velachery-Tambaram Main Road/MRTS side, while another provides movement towards Taramani Link Road. Even with these structures, the junction remains one of Velachery’s important congestion points during peak hours.
Taramani, Perungudi and OMR Connectivity
Taramani Link Road provides the main connection from the bypass towards Taramani, Perungudi and the Old Mahabalipuram Road IT corridor. This route is useful for office commuters travelling between Velachery and the major technology and business areas along OMR.
Traffic can build up around Vijayanagar and Taramani Link Road in the morning and evening because city buses, local traffic and IT-corridor commuters use the same road network.
Pallikaranai, Medavakkam and Tambaram Side
From the southern side of Velachery, Velachery Main Road continues towards Pallikaranai and Medavakkam, with onward connections towards Tambaram, Perumbakkam and other expanding residential areas of South Chennai.
Velachery Bypass Road therefore works as a useful feeder for people travelling from central Velachery towards the southern suburbs. It is not itself the road to Tambaram, so motorists should follow Velachery Main Road and current junction signs after leaving the bypass.
Guindy and Central Chennai Connectivity
The western and north-western road network from Velachery connects towards Guindy, Five Furlong Road, Sardar Patel Road and Anna Salai. Guindy is an important employment and transport hub with suburban rail, Metro and major road connections.
Commuters heading from Velachery Bypass Road towards central Chennai can use either the Guindy side or MRTS depending on the final destination and traffic conditions.
MRTS Connectivity
Velachery MRTS Station is the most important rail-transit point near the bypass. It provides direct suburban-style urban rail connectivity towards Taramani, Thiruvanmiyur, Mylapore, Chepauk, Chennai Beach and other stations along the MRTS corridor.
A major 2026 improvement is the extension of MRTS services from Velachery to St Thomas Mount. Trains now continue beyond Velachery through the new extension, giving passengers access to the major St Thomas Mount interchange with Chennai Metro and suburban rail. This has made rail travel from the Velachery Bypass area more useful for airport-side and western Chennai journeys as well.
Bus and Local Transport
Vijayanagar Bus Terminus is one of South Chennai’s important city-bus points. Services from the Velachery area connect with Tambaram, Medavakkam, Pallikaranai, Madipakkam, Sholinganallur, Perungudi and other parts of the city.
Autos and app-based cabs are widely available along the bypass. During peak periods, pickup and drop activity close to the bus terminus and major commercial buildings can slow the service lanes and junction approaches.
Airport Connectivity
Chennai International Airport is the nearest airport. From Velachery, the practical route usually goes through the Inner Ring Road, St Thomas Mount, Guindy or Pallavaram-side road network depending on traffic.
The new MRTS extension to St Thomas Mount also provides another public-transport option because passengers can interchange there for Metro or suburban rail connections. Travellers with luggage or early-morning flights may still find a cab more convenient.
Nearby Areas Around Velachery Bypass Road
TANSI Nagar, Dhandeeswaram, AGS Colony and several Velachery residential pockets lie close to the bypass. Madipakkam and Pallikaranai are reached towards the southern side, while Taramani and Perungudi lie towards the east.
Phoenix Marketcity and the Guru Nanak College side are reached through the Velachery Main Road/Guindy side rather than by staying only on 100 Feet Bypass Road. The wider area is densely developed and has strong road access to South Chennai’s major commercial zones.
Shops and Daily Facilities
Velachery Bypass Road is lined with supermarkets, restaurants, banks, pharmacies, electronics stores, vehicle showrooms and neighbourhood businesses. The corridor is therefore very different from an outer-city bypass where facilities may be limited.
Hospitals, schools, malls and larger commercial facilities are available across Velachery, Guindy and Taramani. The main challenge is usually traffic and parking rather than lack of services.
Traffic Conditions and Monsoon Issues
Traffic is often heavy around Vijayanagar Junction and the approaches to Velachery Main Road and Taramani Link Road. Two-wheelers, city buses and turning traffic can create slow movement even outside the traditional office rush.
Velachery is also a low-lying, flood-sensitive part of Chennai. In 2026 residents again raised concerns about drainage and the macro canal carrying excess water from the Velachery Lake side through the Vijayanagar-Taramani corridor. During intense monsoon rain, commuters should check waterlogging and traffic conditions before travelling.
Proposed Velachery Flyover: 2026 Status
Tamil Nadu’s 2025-26 budget proposed a roughly 3 km flyover in the Velachery corridor towards Guru Nanak College, and the Greater Chennai Corporation issued a tender for a major flyover between the Sardar Patel Road-Velachery Main Road side and Guru Nanak College junction.
The tender value was about Rs 231.86 crore, but by July 2026 the project had been put on hold while the Corporation sought additional state funding. Travellers should therefore not assume that a new flyover is currently under active construction across the full proposed stretch.
Conclusion
Velachery Bypass Road is a short but important South Chennai arterial corridor, officially listed as the 1.9 km SH-48C and widely known as 100 Feet Bypass Road. Vijayanagar Junction is its main transport landmark, linking the road with Velachery Main Road, Taramani Link Road, the MRTS and routes towards Pallikaranai, Medavakkam, Guindy and OMR. The 2026 MRTS extension to St Thomas Mount has improved public-transport connectivity, while road congestion and monsoon drainage remain practical concerns. The proposed large Velachery flyover should still be treated as a planned/on-hold project rather than an active completed route.
FAQs About Velachery Bypass Road
Q1. Is Velachery Bypass Road the same as 100 Feet Road?
In Velachery, the names are commonly used for the same SH-48C corridor. If a cab driver or business address says ‘100 Feet Bypass Road’, the reference is normally the Velachery Bypass Road around the Vijayanagar side.
Q2. Which junction should I use for Velachery MRTS Station?
Vijayanagar Junction is the main road reference. From there, follow the Velachery-Tambaram Main Road/MRTS side rather than continuing deeper along 100 Feet Bypass Road.
Q3. Can I reach OMR directly from Velachery Bypass Road?
Use the Vijayanagar connection to Taramani Link Road and continue towards Taramani, Perungudi and OMR. During office peaks, this route can become congested, so live traffic should decide the exact approach.
Q4. Is the new Velachery-St Thomas Mount MRTS extension operational?
Yes. MRTS services were extended from Velachery to St Thomas Mount in March 2026, giving passengers a direct interchange with Chennai Metro and suburban rail at St Thomas Mount.
Q5. Is the proposed new flyover towards Guru Nanak College under construction now?
The project was tendered, but by July 2026 it had been put on hold pending additional funding. Do not plan a route assuming a new completed or continuously active flyover work zone across the full proposed corridor.
Q6. Does Velachery Bypass Road have a toll?
No. It is an urban state-highway/city road corridor, not a tolled expressway or national-highway bypass.
Q7. What should I check before travelling during heavy rain?
Check live traffic and waterlogging reports around Vijayanagar, Taramani Link Road and low-lying Velachery streets. Drainage and canal-related flood risk remains an important local issue during intense monsoon rain.
Q8. Which is better for Chennai Airport from Velachery Bypass: road or rail?
For passengers with luggage or very early flights, a cab is usually simplest. At other times, the MRTS to St Thomas Mount followed by the Metro/suburban interchange can be useful, depending on the terminal and service timings.
