Sion Circle — the prominent roundabout junction at the heart of Sion, central Mumbai — is one of the most strategically positioned and most historically significant traffic junctions in the Mumbai Metropolitan Region. Sion (pronounced “Sai-yan” from the Marathi word “Sheev” meaning boundary) was the northern limit of old Bombay during the British colonial era, and its circle today serves as the crossing point of some of Mumbai’s most critical arterial roads — the Eastern Express Highway, Dr. Ambedkar Road, and Sion-Trombay Road — making it a vital convergence of east, central, and south Mumbai’s daily commuter flows. With the BEST Sion Bus Depot, Sion Railway Station on the Harbour Line, and Mumbai Metro Line 3 (Aqua Line) all accessible from the circle’s immediate vicinity, Sion Circle is one of central Mumbai’s most genuinely multi-modal transit nodes — a junction where suburban rail, city bus, Metro, and major highway infrastructure all converge.
