Bonang Road

Bonang Road commences on the Victorian side of the interstate border with New South Wales, south of the town Delegate in the Snowy Mountains of the Great Dividing Range, and heads south, passing through the settlements of Bonang, Goongerah and Nurran, running through valleys to the east of the Snowy River, eventually ending on the river's eastern bank, terminating at the intersection with Princes Highway at Orbost.

By October 2024 the road was sealed for its entire length. Due its narrow, twisting route, following steep sides of ridges and creeks, Bonang Road provides a slower journey (nearly three hours, as opposed to one and three-quarter hours) compared with the equal distance of the Princes Highway (route A1, Orbost to Cann River) and Monaro Highway (route B23, Cann River to Bombala) route. The loop from Orbost to Bombala, with a return via Monaro Highway, is well known to motorbike riders as a scenic but difficult ride.

The road was established after 1852, to allow access for people going to the gold mining in the Bendoc area south of Delegate,^[5] and as an access road for logging and other forestry activities in the late 19th and early 20th centuries. It is still primarily used for access to forest plantations in the Victorian State Forest areas adjoining the Snowy River National Park to its west and Errinundra National Park to its east. The road gives access to the Valley of the Giants area where the old-growth forest is a tourist attraction.^[6]

The passing of the Country Roads Act 1912^[7] through the Parliament of Victoria provided for the establishment of the Country Roads Board (later VicRoads) and their ability to declare Main Roads, taking responsibility for the management, construction and care of the state's major roads from local municipalities; the later passing of the Highways and Vehicles Act 1924^[8] provided for the declaration of State Highways, roads two-thirds financed by the state government through the Country Roads Board. Bonang Highway was declared a State Highway in 1933,^[9] slowly constructed from Orbost through Bonang to Delegate over the border in New South Wales (for a total of 73 miles); before this declaration, the road was referred to as the Orbost-Delegate Road;^[2] the declaration was made for "this very important road, which is considered to be the most direct road from the Princes Highway to Canberra",^[2] a role later delegated to Cann Valley Road (later the Victorian section of Monaro Highway).

Bonang Highway was signed within Victoria as State Route 199 in 1986; with Victoria's conversion to the newer alphanumeric system in the late 1990s, this was replaced by route C612 (the New South Wales section remains unallocated).

The passing of the Transport Act 1983^[10] updated the provision for the declaration of State Highways through the Road Construction Authority (later VicRoads). In this rare case, its status as a State Highway was downgraded to that of a Main Road, and Bonang Road was declared along the same alignment in November 1990,^[3] from the border with New South Wales and ending at Princes Highway in Orbost.

The passing of the Road Management Act 2004^[11] granted the responsibility of overall management and development of Victoria's major arterial roads to VicRoads: in 2004, VicRoads re-declared the road as Bonang Road (Arterial #5952), beginning at the border with New South Wales and ending at Princes Highway in Orbost.^[4]
