It covers the western edge of the Tamar River, from Launceston to the beach town of Greens Beach.

Four shielded routes terminate at the intersections of streets in the Launceston CBD.

Because all the involved streets are one-way each route has separate inbound and outbound termini.

Distances from each terminus to a point on the route may not be identical.
