Katamnallur Gate Flyover is an important road landmark on Old Madras Road / NH-75 on the eastern side of Bengaluru. The junction lies in the Kattamanallur-Sannatammanahalli belt between the city’s expanding Whitefield-Kadugodi side and Hoskote. It serves a corridor used by city commuters, airport buses, local residents and long-distance traffic travelling towards Kolar and farther east.
The flyover area has also been affected by phased construction and service-road changes in recent years. Public reporting in 2025 noted that one direction towards Bengaluru was already operational while work on the opposite movement continued and caused major congestion. Because lane arrangements can change as work progresses, this is a location where current signs and live navigation are particularly important.

Where Is Katamnallur Gate Flyover Located?
Katamnallur Gate is located on NH-75, also commonly called Old Madras Road, east of Bengaluru’s main urban core and before Hoskote. Karnataka road records identify Katamnallur Cross on NH-75, while the surrounding junction is also an important connection point for roads towards Whitefield, Varthur and other eastern suburbs.
The immediate area has seen rapid residential and commercial development, including large apartment and office projects near Sannatammanahalli and Huskur. As a result, the junction now carries much more local turning traffic in addition to the long-distance highway flow.
Connectivity of Katamnallur Gate
Westbound NH-75 connects Katamnallur Gate with KR Puram and the wider Bengaluru urban area. Eastbound traffic continues towards Hoskote, Kolar and the Andhra Pradesh / Tamil Nadu connecting highway network. Budigere Cross is another important nearby junction on the same corridor.
Local roads from Katamnallur Gate also provide connections towards Whitefield and Varthur-side areas. This makes the junction useful for commuters who want to move between the Old Madras Road highway and the rapidly growing eastern technology and residential belt without travelling deep into central Bengaluru first.
Directions to Katamnallur Gate Flyover
The correct route depends on whether the trip is a straight NH-75 journey or a local movement towards Whitefield, Sannatammanahalli or adjoining roads.
| Starting Point | Route / Direction |
| KR Puram / Central Bengaluru | Follow Old Madras Road / NH-75 east towards Hoskote and continue to Katamnallur Gate. Use the correct service lane for local access. |
| Hoskote / Kolar | Travel west on NH-75 towards Bengaluru and follow signs around Katamnallur Gate and Budigere Cross. |
| Whitefield / Kadugodi | Use the eastern local road network towards Katamnallur Gate, then join NH-75 in the required direction. |
| Budigere Cross | Travel along NH-75 between Budigere Cross and Katamnallur Gate; remain alert for service-road entries and local turning traffic. |
| Varthur side | Use the local east-Bengaluru connector towards Katamnallur Gate and enter NH-75 only after selecting the correct Bengaluru- or Hoskote-bound lane. |
Because service-road and lane arrangements have changed during flyover construction, motorists should rely on current road signs and live navigation instead of an old saved route.

3. Can Katamnallur Gate be used to reach Whitefield?
Yes. Local roads from the junction connect towards the Whitefield/Kadugodi side, but the final route depends on the precise destination and current traffic.
