Metroad 10 changes names several times as it passes through the city. Its names from Artarmon to Mona Vale are (bold are motorway grade): Pacific Highway; Falcon Street; Military Road; Spit Road; Manly Road; Burnt Bridge Creek Deviation; Condamine Street; Pittwater Road.
The Metroad 10 is the main transport link to and through the Northern Beaches district of Sydney. Its crossing of Middle Harbour on the Spit Bridge has become infamous as one of the most congested road links in the city, made worse by the regular opening of the bridge to allow boats to pass by.
It is believed that this route will be known as the A8 when alphanumerical route numbering is introduced in New South Wales.
Metroad 8 has never existed in Sydney, and most likely never will be.
