Driving southbound on Metroad 10 over the Spit Bridge
|Length:||23 km (14 mi)|
|Existed:||December 1998 – present|
Metroad 10 is one of Sydney, Australia's metropolitan arterial routes, called Metroads. The Metroad 10 route runs for 23 kilometres from North Sydney to Mona Vale. The route includes parts of several different roads. The Metroad 10 route designation replaced the former 'State Route 14' designation in December 1998.
Metroad 10 starts at the Warringah Freeway (Metroad 1) at North Sydney. The Warringah Freeway is also part of Metroad 1, and the Sydney Orbital Freeway. The Metroad 10 route then uses the following roads: Falcon Street; Military Road; Spit Road; Manly Road; Burnt Bridge Creek Deviation; Condamine Street; and then Pittwater Road from Brookvale to Mona Vale. The Metroad 10 route ends at the intersection of Pittwater Road and Barrenjoey Road with Mona Vale Road, (Metroad 3), at Mona Vale.
Metroad 10 is the main transport link through the Northern Beaches district of Sydney. It forms one of only three road connections between the Northern Beaches area, and the rest of Sydney. Metroad 10's 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.
Most of the components of Metroad 10 are old roads. The section of Military Road through Cremorne and Mosman was first built in the 1820s. The earliest bridge at The Spit, linking Mosman to Manly, was opened in 1923, and then rebuilt in the late 1950s with new, wider, approach roads on the southern (Spit Road) and northern sides (Manly Road) of the bridge. The newest section of road is the Burnt Bridge Creek Deviation, a completely new road built the early 1980s to bypass the congested Balgowlah shopping strip on Sydney Road. The route from North Sydney to Mona Vale was designated at 'State Route 14' in 1974. It was re-designated as Metroad 10 in 1998, five years after the first Metroad routes were introduced.
Traffic headed south-east on Metroad 1 and 2 on the Warringah freeway originally had no ability to exit the freeway and enter Falcon Street, so Metroad 10, as originally defined, had a connection further west at Artarmon. When north-facing, tolled, off-ramps were constructed which directly connected the Warringah freeway to Falcon Street from 2007, the Metroad 10 route was truncated at that point.
The majority of Metroad 10 has three lanes in each direction ( with the kerbside lane often obstructed by parking ). There are a few sections with only two lanes in each direction.
Major intersections 
None of the Metroad 10 route is a proper freeway, and it has intersections controlled by traffic lights every few blocks. The Burnt Bridge Deviation, a new section of road opened in 1985, to bypass the congested Balgowlah shopping strip, offers 3 kilometres of almost freeway-grade motoring.
Major roads and routes intersected along Metroad 10 ( from south to north ) include:
- The commencement of Metroad 10 at the intersection of Falcon Street (Metroad 10) with the Warringah Freeway (Metroad 1) at North Sydney.
- The junction of Spit Road and Military Road, at Mosman
- The junction with Sydney Road and, indirectly, to the Wakehurst Parkway, at Seaforth.
- The junction with Condamine Street, at Balgowlah
- The junction with Pittwater Road, at Brookvale
- The junction with Warringah Road, at Brookvale
- The junction with the Wakehurst Parkway, at North Narrabeen
- The junction with Mona Vale Road and Barrenjoey Road, at Mona Vale, where Metroad 10 ends.
