Next round of alphanumeric signs to be updated between Sydney and South Coast

Motorists travelling between Sydney and the South Coast will notice signs on the Southern Freeway and Mount Ousley Road commonly known as the F6, will be gradually updated this month to reflect the route’s new number and name, the M1 Princes Motorway.

Roads and Maritime Services (RMS) General Manager Traffic and Safety Management Craig Moran said major travel routes across NSW have adopted the alphanumeric system to simplify travel in NSW and across the entire eastern sea board.

“From Monday 19 August, signs on the road between Waterfall and Albion Park Rail will be gradually updated to the new name the M1 Princes Motorway as part of the alphanumeric rollout.

“Alphanumeric route numbers are used widely around the world and are already in place in Victoria and Queensland.

“Electronic signs will be in place to advise motorists and help them transition to the new alphanumeric system.

“The alphanumeric system lets motorists know if they are travelling on a motorway (M), route of national (A) or state significance (B) and improves travel route consistency across state borders.

“Several routes have already been updated this year.

“RMS has consulted with emergency services, Destination NSW, tourist operators and mapping providers to ensure uniformity.

“We understand there may be some confusion as people get used to the new system but it will ultimately provide clearer directions for road users.”

All route updates are expected to be completed by the end of 2013.
