The SH1 Mt Victoria Tunnel will close from 9.00pm tonight for routine maintenance. It is expected to reopen by 5,30am on Wednesday 10 October.
NZTA advise that southbound traffic should travel from Patterson Street to Constable Street, Newtown, via Adelaide Road and Riddiford Street, and then on to Wellington Road. A reverse journey should be followed for northbound traffic.
The detour will add around five minutes to journey times.
