The highway forms part of the A6 and connects Hobart with the southern parts of Tasmania.

The original Huon Highway (now known as Huon Road) was a twisty two-lane road skirting around Mount Wellington, but that section of the highway was bypassed in stages when the Southern Outlet was completed in 1968.

[2] This provided a more direct, and higher traffic-capacity, route between Hobart and the Huon Valley.

A few sections of the old highway remain, all within the Huon Valley, and have been upgraded.
