The Curran St northbound on-ramp and the Wellington St northbound on-ramp will also be closed during the same times. This will last for three days.
The full closure between the Symonds St off-ramp and the Fanshawe St on-ramp also cuts off the closest SH16 entry point, causing further delays for motorists.
The SH16 Hobson St on-ramp westbound on-ramp will also be closed.
The closures are dependent on various factors, including wet weather.
An NZTA spokesman said “unfortunately the information contained in the traffic bulletin published on the NZTA Waka Kotahi website on Friday .... was incorrect.
“One lane of the Fanshawe St on ramp is remaining open tonight. The Traffic Bulletin was incorrect listing that on ramp as closed.
“Traffic is able to access the Auckland Harbour Bridge in both directions at all times during the maintenance work that’s being carried out this month.”
