Locals understood that Covid-19 and the July flood had caused delays, but couldn't understand why it had taken so long to install the rails.
"It got to the point where I wanted to go down with my tractor and move the barriers so we could use the bridge,'' she said.
Calls to the phone numbers listed on signs at the site had just led to buck-passing.
''It seems they just don't care because we live in the wops,'' she added.
Dawn's husband, Dave, said the detour and bridge-related road works had cost his Suzuki Swift two sumps so far, and he had held off replacing the cracked windscreen until the bridge was finished. He was pleased to see the new bridge open at last.
''It'll save us a lot of driving. And even with the old bridge we couldn't get harvesters over because of the weight limit. The other bridge (on Ninihi Rd) is too narrow, so we had to drag them through the creek instead," he said.
Meanwhile one of their neighbours, who was due to have a baby any day, would be relieved to be spared making a dash to hospital the long way around.
Ōtaua dairy farmer Richard Dampney said logging trucks had used the old bridge until 2018, when a 5000kg weight restriction was imposed due to safety concerns. They had been using Ninihi Rd since then.
''Then in mid-May they ripped the old bridge out, but it's taken them that long to finish it. It's the inconvenience," he said.
Dampney headed to his farm early each day for milking, came home for breakfast, went back to work, drove home for lunch, then went back to the farm again. The 4km trip expanded to 10km each way with the detour. People living in Ōtaua Valley had also been forced to drive the long way around, often in small cars not suited to the road conditions.
Far North District Council spokesman Richard Edmondson said the bridge was found to be failing during a routine inspection. A contract to replace it was awarded on March 3, shortly before the Covid-19 lockdown.
The delays were due to the ferocity of the 1-in-500-year storm that dumped 220mm of rain on the Mid North in a few hours, issues getting the guard rails made, and unexpected problems with the land around the bridge, meaning parts of it had to be rebuilt from the ground up.
Guard rails were not standard parts, and in this case had to be modified at the entry and exit points after other changes were made to the bridge. Those changes were not finalised until early November.
''Without guard rails, the bridge was not considered safe for public use. That is why the bridge remained closed until designs were finalised, materials procured and the rails installed,'' Edmondson said.
The council regretted the inconvenience to residents, he added.
According to a council report, the cost of replacing the bridge increased from an initial $999,000 to $1.22 million. The extra funding was approved at an Infrastructure Committee meeting in September.
