Since 1968 It's been a vital link for those commuting between the northern suburbs and Sydney.
Originally it was planned to link Sydney with the northern beaches but over the past decade it has been integrated into the orbital network of freeways. Much of the traffic originates from the M2 which leads towards the north west suburbs of Baulkham Hills.
There is a footbridge that crosses the expressway linking Neutral Bay with North Sydney (17 lanes wide at last count) and the views are lovely.
