Christchurch City Council contractors are investigating the issue and working to repair a major fault in the traffic signal cabling, which affects the safety of the intersection.
“Riccarton Road is a key route, particularly at this time of year with holiday shoppers heading to the mall, so our contractors are working as hard as possible to fix and reopen the road,” Transport Operations Manager Stephen Wright said.
“If you can, avoid the area and use an alternative route while work is ongoing.”
“We are still working through the detail of what’s needed so we will provide further updates on the full scale of work once we know more, and it has been finalised,” Mr Wright said.
“We know this isn’t ideal right before Christmas, but unfortunately it is unavoidable as it affects the safety of all road users so we want to thank everyone for their patience while we do this urgent work.”
