Doncaster–Mordialloc Road

Doncaster–Mordialloc Road is a major arterial road through the eastern and south-eastern suburbs of Melbourne. This name is not widely known to most drivers, as the entire allocation is still best known as by the names of its constituent parts: Victoria Street, Wetherby Road, Middleborough Road, Stephensons Road, Clayton Road and Boundary Road. This article will deal with the entire length of the corridor for sake of completion.

Route
Doncaster–Mordialloc Road commences at the intersection of King and Victoria Streets at Doncaster East and heads south as a two-lane, single carriageway road along Victoria Street until it intersections with Doncaster Road, changing its name to Wetherby Road and continuing south as a four-lane, single carriageway road, before crossing Koonung Creek and meeting with Eastern Freeway at an interchange in Box Hill North. It changes names again to Middleborough Road and continues south through Box Hill before intersecting with Highbury Road in Mount Waverley, changing name again to Stephensons Road, and continuing south through Mount Waverley. It intersects with Ferntree Gully Road in Oakleigh East, changing names again to Clayton Road, and continues through Clayton, intersecting with Kingston and Heatherton Roads in Clayton South and changes name a final time to Boundary Road, widening to a four-lane, dual-carriageway road through Dingley, before eventually terminating at the bridge over Mordialloc Creek in Braeside, continuing southeast-wards as Wells Road.

History
The passing of the Country Roads Act of 1958 (itself an evolution from the original Highways and Vehicles Act of 1924 ) provided for the declaration of State Highways and Main Roads, roads partially financed by the State government through the Country Roads Board (later VicRoads). Doncaster–Mordialloc Road was declared a Main Road on 7 September 1960, between Doncaster Road in Doncaster and Wells Road in Mordialloc, but was still sign-posted as its constituent parts.

Doncaster–Mordialloc Road was signed as Metropolitan Route 23 between Doncaster Road and Wells Road in 1989.

The passing of the Road Management Act 2004 granted the responsibility of overall management and development of Victoria's major arterial roads to VicRoads: in 2004, VicRoads re-declared Doncaster–Mordialloc Road (Arterial #5803) from King Street in Doncaster East to Wells Road in Braeside. The road is still presently known (and signposted) as its constituent parts along its entire length.
