The Tweed Shire Mayor has confirmed the road Stephanie King was driving down when her car skidded into the Tweed River on Monday, was open.
The 43-year-old died in the tragedy, along with her 7-year-old son Jacob and 11-year-old daughter Ella-Jane.
There was speculation Stephanie ignored road closure signs when she drove down Dulguigan Road, which was reportedly closed to motorists at the time of the incident due to debris and mud from the recent floodwater.
Mayor Katie Milne quashed the rumours on Thursday night.
She released a statement confirming the road was open, despite being flood affected.
"There has been much speculation about the status of the road, and I just wanted to provide the family and friends with certainty and clarification that Ms King was not travelling on a closed road," she wrote.
The statement said signage at Dulguigan Road was placed by Council, at police request, after the accident.
Ms Milne said she was deeply saddened by the incident and sent her condolences and prayers to the victims' family and friends, and the whole Tumbulgum community.
"This tragedy has rocked us all to the very core at a time when emotions were already raw following the worst floods in our history," she said.
