Rosebank College now stands on the former Rosebank Estate, and the heritage-listed building of the private school stands adjacent to the road at Five Dock. 1900s–present: Motorisation Sydney Municipal Council began widening the major routes into the city centre in 1911, including the construction of Broadway and the widening of the cutting on Parramatta Road adjacent to Sydney University. In the 1920s, the road was sealed and tramlines were removed from the road. Sheep and cattle were still crossing Parramatta Road at Homebush as late as the 1960s. Increased traffic congestion along the road steadily made it less attractive for residential and commercial use during the 20th century. By the last quarter of the 20th century, the only active businesses on many stretches of the road were car dealerships. The decline of industry in the Inner West also drove the decline of commercial areas formerly catering to factory workers. By the end of the 20th century, proposals to revitalise Parramatta Road and make it more attractive were regularly made. One of these proposals was made in 2012, which would have widened and lowered the road below street level in a "slot" as part of the Roads & Maritime Services WestConnex motorway proposal. This plan was abandoned, and the WestConnex proposal was later changed to a pair of tunnels parallel to Parramatta Road and connecting to the existing M4 motorway. The new extension was known as M4 East and was eventually built between the end of the existing M4 motorway in North Strathfield and Haberfield, where it connected to the A4 road. The new tunnels opened to traffic in July 2019. The project resulted in the creation of a new entry and exit ramp on Parramatta Road in Ashfield, the narrowing of westbound traffic lanes for through-traffic to one lane at either end of the tunnel, and the demolition of a large number of houses in Ashfield and Haberfield to make way for the tunnel ramps. Criticism The road has been criticised by the community for its traffic pollution, congestion, and for its vacant shops and rundown buildings, particularly between Leichhardt and Concord, and local government has been accused of failing to adopt policies to encourage the redevelopment and regeneration of vacant sites. A local mayor described it as a "varicose vein". A NSW Business Chamber Executive Patricia Forsythe said that the road is "one of the least attractive commercial areas
