Barton Highway

Barton Highway commences at the interchange with Hume Highway northeast of Yass and heads in a southerly direction as a four-lane, dual-carriageway freeway, before narrowing to a two-lane, single-carriageway highway south of the interchange with Yass Valley Way where it meets its old alignment, and continues south through undulating hills to the village of , before crossing the border into the Australian Capital Territory (ACT) just outside the village of , before eventually terminating at the intersection with Federal Highway and Northbourne Avenue at . The Gundaroo Drive/Barton Highway round-about is surrounded by a number of trees to the south of the intersection. The pine tree plantation was originally planted in the shape of a map of Australia. ==History==

The passing of the Main Roads Act of 1924 through the Parliament of New South Wales provided for the declaration of Main Roads, roads partially funded by the State government through the Main Roads Board (MRB, later Transport for NSW). Main Road No. 56 was declared along this road on 8 August 1928, from Yass via Murrumbateman to Lyneham (and continuing northwards via Cowra to Forbes, Parkes, Dubbo, Gilgandra and Coonamble eventually to Walgett, and southwards via Canberra eventually to the intersection with Queanbeyan-Braidwood Road, today Kings Highway, at Queanbeyan); to provide for additional declarations of State Highways and Trunk Roads, this was amended to Trunk Road 56 on 8 April 1929. The original purpose of the Yass-Canberra Road was to connect surrounding towns to farming locations in the Yass Valley, and later with the newly-established national capital. The Department of Main Roads, which had succeeded the MRB in 1932, declared State Highway 15 on 19 February 1935, from the intersection with Hume Highway near Yass via Murrumbateman to the border of the Federal Capital Territory (today Australian Capital Territory) at Hall, subsuming the existing portion Trunk Road 56 from Yass to Hall; and fully sealed by 1960. The first realignment occurred during the late 1970s, when the southern terminus of the highway was relocated north, to the north of the Yowani Country Club. The highway's former alignment, near the historic Cooma Cottage, east of the Yass River, was renamed Kirkton Road and Dog Trap Road. The passing of the Roads Act of 1993 through the Parliament of New South Wales updated road classifications and the way they could be declared within New South Wales. Under this act, Barton Highway today retains its declaration as Highway 15, from the intersection with Hume Highway near Yass to the border of the Australian Capital Territory at Hall. Barton Highway was signed National Route 25 across its entire length in 1956. The Whitlam government introduced the federal National Roads Act 1974, where roads declared as a National Highway were still the responsibility of the states for road construction and maintenance, but were fully compensated by the Federal government for money spent on approved projects. Murrumbateman bypass and staged duplication The Barton Highway passes through farmlands and the NSW town of Murrumbateman. In October 2001 the Australian Government announced that they would bypass the town to the east. A$20 million was set aside in the 2006 federal budget for planning and duplication costs associated with the bypass. The same year, the NRMA had named the Barton Highway as the worst highway on the AusLink National Network in New South Wales; accounting for three road fatalities annually. While of the highway are located in New South Wales (NSW), only of the NSW section are dual carriageway. and Federal governments have committed funding towards improvements to the Barton Highway, including a bypass east of Murrumbateman and a staged duplication to create of dual carriageways. Stage one of construction work has commenced and is scheduled to be completed by 2023. ==Major intersections==
