Bengaluru–Mysuru Expressway Interchange & Exit Guide: Trumpet Ramps & Service Road Ramps
Refueling on Bengaluru–Mysuru Expressway (NH 275)?
Access all 45 verified operational CNG bunks mapped in sequential driving order with live distance milestones, operating hours, and 1-tap Google Maps navigation.
Access-Controlled Design of Bengaluru–Mysuru Expressway (NH 275)
The 118-kilometer Bengaluru–Mysuru Expressway (NH 275) is built to full access-controlled expressway standards. Unlike standard open-access highways where vehicles merge freely from village crossroads, entry to and exit from the main 10-lane expressway carriageway is permitted strictly via grade-separated trumpet and diamond interchanges.
Understanding the exact milestone locations of exit ramps is vital for motorists: missing your exit requires driving 10 to 18 kilometers to the next interchange turnaround, as reversing or U-turns on the main carriageway are strictly prohibited and penalized by automated ANPR cameras.

Rules for Entering & Deceleration Lanes
Every interchange on NH 275 is equipped with a 250-meter dedicated deceleration lane. When approaching your desired exit, move into the extreme left lane at least 1 kilometer in advance. Decelerate smoothly to 40 km/h before negotiating the loop ramp.
Service roads run continuously on both sides of the expressway. Motorists seeking food plazas, local handicrafts, or CNG bunks can exit cleanly at any trumpet interchange and re-enter after refueling without paying duplicate toll fees.
