A0 road (Sri Lanka)

The A0 road in Sri Lanka is a major arterial route that forms a ring road around the city of Colombo. It is also referred to as the Colombo Outer Circular Highway. The A0 designation signifies its importance as a primary trunk road within the Sri Lankan road network.

The highway is designed to alleviate traffic congestion within the city of Colombo by providing an alternative route for vehicles traveling through the metropolitan area, rather than having to navigate the city's center. The A0 road connects various major A-class roads radiating outward from Colombo, facilitating smoother and faster transit between these routes.

The Colombo Outer Circular Highway project has been implemented in phases, with different sections being constructed and opened at various times. The goal is to create a complete bypass around the city, improving overall transportation efficiency and reducing travel times for both commercial and private vehicles.

The A0 road plays a crucial role in Sri Lanka's transportation infrastructure, supporting economic activity and facilitating the movement of goods and people across the country.
