The existing M4 motorway which it links from Hamilton CBD to northwestern suburbs is a time-waster. Every day, it chokes up with thousands of cars in a traffic jam every morning when the workers go to their work in the City Centre. Hamilton City Council have recieved a lot of complaints from the locals, and demands to improve the M4 motorway.

Hamilton City Council knew that M4 couldn't be improved because once when the construction begins at M4, then the motorway would be closed, then workers will be forced to use the suburban road to the city, which it will take them around two extra hours to get to their work. The City Council have decided to build a new motorway which it also links from City Centre to the northwestern suburbs. The new motorway is M8, and it connects from Collins Street in the City Centre to M4/M8 Interchange at McLaughlin (northwestern suburb).

The construction have just completed and opened to the public, and the percentage of usage at M4 is 84% but dropped to 49%, and more and more people use the new M8. The new M8 motorway is entirely evelated, and links directly to the city without any exits, it is similar to the method of expressways and freeways. Hamilton's city-wide traffic jam have reduced a little bit because of an addition of the new motorway. Hamilton City Council is now considering to toll M8 motorway, because it would provide a revenue to the City's economy. The proposed fixed toll price is $2.80 to use the two-kilometre motorway. The old M4 motorway won't be closed and demolished. M8 now adds to the motorway system in Hamilton with four of other motorways.
