The M4 Motorway will be shut down over the June long weekend as work continues on The Northern Road upgrade.
With a new bridge over the M4 at The Northern Road now open, the existing bridge needs to be removed.
Traffic data indicates that traffic is usually lower in volume over the June long weekend.
The M4 will be closed from 9pm on Friday, June 7 until 4am on Tuesday, June 11 in both directions at The Northern Road.
The work could create major traffic gridlock in Penrith with the busiest times anticipated to be between 10am and 3pm on Saturday, June 8 and 10am and 2pm on Sunday, June 9.
Vehicles will still be able to enter and exit the M4 in both directions at The Northern Road during the closure, however traffic is expected to be busy.
