Transport for New South Wales (TfNSW) has forged a strategic partnership with Seymour Whyte and Turnbull Engineering, forming the Mulgoa Road Upgrade Alliance. Their collaborative effort is dedicated to enhancing Mulgoa Road in Sydney’s western region.

The upgrade between Jeanette Street, Regentville and Blaikie Road, Jamisontown encompasses various critical components aimed at modernising the road infrastructure and fostering overall development.

Key project features

  • Expanding Mulgoa Road: Transformation of Mulgoa Road into a six-lane divided thoroughfare, providing three lanes in each direction along with a central median.
  • Utility Relocation: Relocating intricate utilities including gas, water, sewer, and electricity and communications to facilitate the road upgrade.
  • Traffic Flow Restriction: Converting Factory Road into a left-in access only route, enhancing safety. Restricting Glenbrook Street to left-in only access to Peter Court.
  • Enhanced Turning Access: Extending and augmenting turning lanes on Mulgoa Road to provide improved access to the M4 Motorway.
  • Tunnel Access Modification: Eliminating tunnel access to the Penrith Homemakers Centre at Wolseley Street by introducing dual right-turn lanes on Mulgoa Road.
  • Bus Priority Lanes: Implementing dedicated bus priority lanes at Wolseley Street and Glenbrook Street intersections.
  • Active Transport Corridor: Creating an active transport corridor along the eastern side of Mulgoa Road to promote cycling and pedestrian activities.
  • Transit Zone Connection: Establishing a transit zone connecting Hatchinson Crescent, Huron Place, and Peter Court, enhancing mobility for both vehicles and cyclists while providing an adjacent footpath.
  • Noise Abatement: Constructing a noise wall on the eastern side of the road, spanning from Glenbrook Street to the M4 Motorway.
  • Future Expansion Preparation: Incorporating preparations for future road widening, both to the north and south.
