Gemini Flyover is the popular name of Chennai’s historic Anna Flyover at Gemini Circle on Anna Salai. It is a dual-armed grade separator in the central business district, where through traffic on Anna Salai passes above busy local movements connected with Nungambakkam High Road, Cathedral Road and the surrounding Teynampet-Thousand Lights area. The flyover has been part of Chennai’s road landscape since 1973.
Readers should note that Gemini Flyover and Anna Flyover are not two separate structures. “Gemini” remains the familiar local name because Gemini Studios once stood in this area, while Anna Flyover is the official name. This distinction is useful when searching maps, booking a cab or reading traffic advisories, since either name may be used for the same junction.

Where Is Gemini Flyover Located?
Gemini Flyover is at Gemini Circle on Anna Salai, between Thousand Lights and Teynampet in central Chennai. The junction is close to Cathedral Road, Uthamar Gandhi Salai/Nungambakkam High Road and Gopalapuram, with many offices, hotels, hospitals and institutional buildings in the surrounding streets.
Because the name “Gemini” is still widely used by residents, taxi drivers and businesses, it often appears in directions even when official maps label the structure Anna Flyover. Both names lead to the same central Chennai landmark.
Connectivity of Gemini Flyover
The flyover supports through movement along Anna Salai, one of Chennai’s most important arterial roads. Southbound traffic continues towards Teynampet, Nandanam, Saidapet and Guindy, while northbound traffic moves towards Thousand Lights and the central city. Surface roads handle access to Nungambakkam and Cathedral Road-side localities.
Gemini Circle is therefore useful for trips across the central business district as well as for local access. It also sits close to the Blue Line Metro corridor, giving commuters an alternative when Anna Salai is congested. In 2026, separate elevated-road construction on Anna Salai farther south can still influence journey times through this area.
Directions to Gemini Flyover
Use the flyover when your route calls for through movement on Anna Salai. Local turns around Gemini Circle are generally taken from the surface lanes.
| Starting Point | Route / Direction |
| Central Chennai / Thousand Lights | Head south on Anna Salai towards Gemini Circle and choose the through flyover lane or surface lane according to your destination. |
| Teynampet / Nandanam | Head north on Anna Salai towards Gemini Circle and move into the correct lane before the two arms separate from local traffic. |
| Nungambakkam | Approach via Nungambakkam High Road/Uthamar Gandhi Salai and follow the signed movement into Anna Salai. |
| Cathedral Road | Use Cathedral Road towards Gemini Circle and remain on the surface junction for the required Anna Salai or Nungambakkam turn. |
| Gopalapuram / Alwarpet | Use the Cathedral Road-Teynampet network towards Gemini Circle and join the correct Anna Salai direction. |
| Royapettah / Greams Road Side | Use the appropriate central-city road towards Thousand Lights/Gemini and enter Anna Salai at a permitted junction. |
Do not follow an old route blindly when there is major work elsewhere on Anna Salai. Congestion from the Teynampet-Saidapet elevated-corridor project can alter travel times even though Gemini Flyover itself is a separate structure.

Public Transport and Metro Access
Anna Salai is a major MTC bus corridor, and frequent bus, auto and cab services are available around Gemini Circle. Chennai Metro’s Blue Line runs along the wider Anna Salai corridor, with AG-DMS and Thousand Lights serving the area from opposite sides of the junction.
For a cab or auto pickup, choose a side road or marked stopping area rather than the flyover arm itself. The surface junction is busy and the elevated lanes are intended for continuous through movement.
Driving Tips for Gemini Flyover
• Remember that Gemini Flyover and Anna Flyover are the same place, so either name may appear in navigation.
• Choose the surface lane early if you need Cathedral Road or Nungambakkam-side access.
• Expect high pedestrian, bus and cab activity around the central junction.
• Avoid stopping on either elevated arm, even for a brief passenger pickup.
• Check live traffic for the full Anna Salai corridor because construction farther south can create long queues.
