The annual Bike the Bridge event takes place this weekend and will involve lane closures to the Northern Motorway and Auckland Harbour Bridge between 12am (midnight) and 10am, Sunday 13 November.
The NZ Transport Agency says the Harbour Bridge will be open at all times during this period, however motorists may experience some delays because fewer lanes will be available.
The Northern Motorway's southbound left lane will be closed after the Esmonde Rd southbound on-ramp (which remains open), with the two southbound left lanes will be closed from Onewa Rd and across the Auckland Harbour Bridge until (and including) the off-ramp exit to Shelly Beach Rd.
The Onewa Rd southbound on-ramp (including the bus-only lane) will also be closed during this time. All motorway lanes and exits will be available south of St Marys Bay.
The Northern Busway will also be closed from Constellation Station to the Onewa Rd interchange, with Sunnynook, Smales Farm and Akoranga Busway Stations also closed between 4am and 11am.
