The M5 corridor is the main road freight, commercial and passenger route between Port Botany and Sydney Airport, and south west Sydney. It is part of the National Highway Network connecting Sydney, Canberra and Melbourne.

The NSW Government announced in October 2012 that it would proceed with Infrastructure NSW's recommendation to deliver a motorway scheme for Sydney.

WestConnex is a 33 kilometre motorway proposal which would link Sydney's west with the airport and the Port Botany precinct.

The M5 Motorway comprises two sections

  • Section 1M5 South West Motorway - a 22 kilometre tolled road operated by Interlink Roads, with three lanes in each direction between Camden Valley Way at Prestons and King Georges Road at Beverly Hills
  • Section 2M5 East Motorway - a 10 kilometre road connecting the M5 South West Motorway with General Holmes Drive. The M5 East includes two four kilometre tunnels between Bexley Road at Earlwood and Marsh Street at Arncliffe. Each tunnel carries two lanes of traffic.

Plans to expand the M5 East are described in the WestConnex motorway scheme that was announced by the NSW Government in October 2012. Find out more about WestConnex and what this means for the M5 East.

In recent years traffic levels and the high number of heavy vehicles on the M5 have the corridor operating at or near capacity, not just in peak hours. Currently 95,000 vehicles per day use the M5 tunnel with very little variation in numbers from 6am to 6pm. This congestion impacts on Sydney's economic productivity and competitiveness, particularly moving passengers and freight in and around Port Botany and Sydney's international and domestic airports.

This situation will be compounded by planned commercial and industrial growth around Port Botany and the airport and planned population and employment growth along the M5 corridor and, in particular, Sydney's south west.

Action by the NSW State Government, coupled with extensive public involvement on future improvements to the M5, will improve this vital corridor. It will also make Sydney a more accessible and prosperous place to live, work and visit in the future.
