Motorists travelling from West Auckland into the city will be adjusting to a motorway change this morning.
One lane on the Northwestern Motorway, between Royal Rd and Lincoln Rd, has been closed off; leaving only two lanes between that stretch.
Traffic was generally flowing well just after 6am.
However, by 6:30am, traffic was starting to build near the Royal Rd on-ramp and further back towards Royal Rd and Makora Rd.
Congestion from Westgate heading into downtown Auckland was also starting to build just before the on-ramp.
