Duplicating the M5 East from King Georges Road Interchange Upgrade at Beverly Hills to a new interchange at St Peters. 

The New M5 will provide twin underground motorway tunnels, nine kilometres long, from Kingsgrove to a new St Peters Interchange at the site of the old Alexandria landfill facility. The St Peters Interchange will provide motorists with connections to Alexandria and Mascot. It also includes connections to the future Sydney Gateway and M4-M5 Link. The New M5 tunnels will be marked for two lanes in each direction, with capacity to add a third and also include underground connection points for the M4-M5 Link and the proposed F6 Extension.  

Local streets and intersections around the St Peters interchange are also being upgraded to ensure safe and efficient connections for the New M5.
