Motorists should consider using the Princes Highway or Marsh Street off ramps instead.

Transport NSW has told motorists to expect delays and to consider using alternate routes, including the Princes Hwy or Marsh St off ramps, instead.

“Motorists should also allow extra travel time as eastbound traffic is heavy in the area,” they said.

“Use an alternative route, plan your journey, expect delays.”

Diversions are in place and motorists can exit at Marsh St and use Airport Dr, Qantas Dr, General Holmes Dr, Mill Pond Rd to Southern Cross Dr.
