Implementing a new alpha-numeric road numbering system

Roads and Maritime Services (RMS) is implementing a new system of alpha-numeric route numbering to significantly improve how motorists can find their way across NSW. For details about the physical works and an update on the progress view the program update.

Alpha Numeric: Important changes to NSW

The NSW government is making a significant improvement to how motorists can find their way across NSW. Roads and Maritime Services (RMS) is implementing a new system of alpha-numeric route numbering.

The new alpha-numeric signage will make it easier for road users to plan their trip, and brings NSW into line with Queensland and Victoria who are already using the nationally-agreed system.

To help you understand the changes in your area and find out when the new signs will appear, download detailed maps, watch our introductory video and read through our list of Questions and Answers.

Route numbers and road names

The existing 'shield' route markers will be replaced with a combination of a letter - either an M (motorway), A (route of national significance) or B (route of state significance) - and a number from 1 to 99.
