The M4 Western Motorway (also known as the M4 Motorway or simply M4) is a 46-kilometre-long (29 mi)dual carriageway motorway in western Sydney, New South Wales, Australia. The toll-free motorway stretches from North Strathfield in the east, where it connects with the Great Western Highway/Parramatta Road as the A4 to Glenbrook in west, where it continues as the Great Western Highway as the A32.
The M4 Western Motorway was formerly known as F4 Western Freeway. It used to be part of the Sydney Metroad 4 until 2013, when the new M4 route designation was proclaimed along the whole motorway.
The M4 Western Motorway was originally constructed in several stages as the F4 Western Freeway between the late 1960s and the mid-1980s, however a lack of funding resulted in the Wran Labor government halting plans to construct the final stage between Mays Hill and Prospect in 1985. In December 1989 work to construct this stage began as a Build-Own-Operate-Transfer project. In return for funding construction StateWide Roads, the consortium awarded the contract to build the stage, was given permission to toll the section between James Ruse Drive and Silverwater Road as traffic volumes on this section were significantly higher than between Mays Hill-Prospect and would allow a shorter toll period with lower tolls. The concession held by StateWide Roads ended on 15 February 2010, with operation of the motorway returned to the Roads and Traffic Authority and the toll removed.
