The NSW Government is investing $600 million to build the M4 Smart Motorway project, which will introduce intelligent technology to the M4 Motorway between Pitt Street, Parramatta and Mulgoa Road, Penrith.
APR 2021Gantry installations
The M4 Motorway will be closed for one night from 11pm, Monday 19 April to 4am Tuesday 20 April to install four final gantries. The motorway will be closed between The Northern Road and Mamre Road, with detours in place. See the April 2021 gantry install notification (PDF, 431Kb) for more details.
To assist with the flow of traffic on the motorway, ramp meters have been installed on entry ramps for the M4 Motorway. This installation has meant that traffic flows consistently onto the motorway reducing the gaps for cyclists to cross over. For the safety of cyclists they should continue to use the alternative route that has been in place since 2017 for travel between Penrith and Parramatta, as their permanent route to the M4. For more information about where this route is located please see the map.
