The southern section upgraded to a six lane motorway was delivered between M1 and Highway 51 on 30 June 2013. The section between Highway 51 and M5 was renamed Highway M51 when a new section directly connected the M1-M5 section to the M5-M4 section of the M0. This new section was completed on 31 August 2013. (Before the new section was completed M0 shared a section with highway M5, see the map to the right.) The short section between M1 and M7 was upgraded to a six lane motorway in 2015.
