was duplicated. The deviations were an attempt to ease the gradients against heavily laden Sydney-bound steam trains. The Breadalbane-Derringullen Creek deviation is in most places quite close to the previous highway, most of which remains for local use. This section also included the abandoning of the route over the Mundoonen Range which, when it was rebuilt in the 1960s, was designed to be duplicated. Between Conroys Gap and Coolac, most of the earlier alignment was replaced in 1983 and 1996 by realignment associated with dual carriageway construction, although sections such as that south of Connors Creek were rebuilt in 1979 with the earthworks being done for a second carriageway, which was subsequently built in 1994. The current route of the highway between Tumblong and Tarcutta is the third route of the highway in this location. The original route led west from Tumblong along the Murrumbidgee River, before turning south over difficult country, crossing what is now the Sturt Highway and rejoining the current route of the highway as Lower Tarcutta Road. This was replaced in December 1938 by the first Tumblong deviation, to the east of the current route. The main features of this section of the highway were a deep, narrow cutting and the reinforced concrete bowstring arch bridge over Hillas Creek. This has been preserved, and is visible on the western side of the highway close to the interchange with the Snowy Mountains Highway. North of Albury, a major deviation of the highway was constructed in the 1930s due to the inundation of the original route caused by the raising of the wall of the Hume Dam on the Murray River. The deviation commences at Bowna and terminates at Guinea St Albury (the first part of the Riverina Highway east from Albury as far as what is now Old Sydney Road was until then the Hume Highway). On the southern side at Bowna Waters the old route terminates at dead end. On the northern side the old route is now a road that services local farms, including Willow Park, with the remainder of the old route now being part of private property and inaccessible to road traffic. Parts of the old route are visible when the waters of Lake Hume are low from the air and satellite imagery (Google Map) Major sections, which have now been bypassed New South Wales Camden Valley Way (formerly ) Remembrance Drive (Old
