Record-breaking flooding created unprecedented traffic chaos on New South Wales roads last week, costing tens of millions of dollars and casting a cloud of uncertainty over the
road's flood resilience
.
Most notably, flooding closed a 20-kilometre stretch of the Pacific Highway dual carriageway between Coopernook and South Taree for almost five days.
Michael Atkinson was one of the motorists frustrated on Wednesday when he was returning home from Maclean in the Clarence Valley.
The trip, which normally takes about five hours, took five times that long.
"I found out there was a road closure when I got within 10 kilometres of Taree," he said.
"I live in Nelson Bay. It took me 26 hours to get home, driving north, camping in Glen Innes, and then driving all the way inland and up through the Hunter Valley."
According to estimates from MidCoast Council, the
financial cost
of the Pacific Highway closure was about $29 million, due to diverted traffic and supply routes.
But drivers have told the ABC the impact of the road closures was exacerbated by incorrect and unclear information about what roads were closed and what alternative routes were available.

After nearly 30 years of dual carriageway upgrades, the Pacific Highway between Hexham and the Queensland border acts as a major supply route for the entire north coast of NSW.
More than 26,000 vehicles use the Pacific Highway near Taree every day, according to Transport for NSW data, with 80 percent cars and 20 percent trucks.
A 2020 floodplain risk management study, commissioned by MidCoast Council, estimated the cost of closing the Pacific Highway near Taree for just a day would be up to $5.79 million.
The study also looked at raising the section of Pacific Highway that crossed the Manning River as an option to improve flood resilience.
It estimated the upgrade would cost about $134 million, and was not financially viable.
Executive director of operations management with Transport for NSW Craig Mason said flood resiliency was something the organisation would look at across the network.
"Stopping the impacts in the future will require a lot of work and expense," Mason said.
"But we're always looking at how we can make the network more resilient and diversions more efficient.
"With the water levels, particularly through Taree being the highest ever, it's quite difficult to try and build networks that can avoid floods in any circumstance."
Multiple drivers told the ABC issues with the Pacific Highway closure were exacerbated by inconsistent information from navigation apps and LiveTraffic, Transport for NSW's real-time information provider.
LiveTraffic is fed real-time information by road crews dispatched from the Transport Management Centre and emergency services.
A forward command centre was set up in Newcastle during the flood emergency.
But navigation apps were often unclear about which routes were open or closed, leading to people becoming stranded in flood-affected areas.
Over two days, about 20 people arrived in the remote valley community of Killabakh, north-west of Taree, after misdirection by navigational aids.
Killabakh Rural Fire Service senior deputy captain Greg Hale and his team, on stand-by for flood rescues, met the new refugees to the valley.
"Most of them consulted LiveTraffic, which is what you're told to do in emergency situations," Hale said.
"And they were then advised they could come over Comboyne Mountain into Killabakh to get further south in their travels, but Killabakh itself was flooded in.
"The information that was available to them about the way they could get to their destination sent them over the mountain and was certainly inappropriate."
The Rural Fire Service crew enacted the local emergency management plan and opened the community hall as a shelter for those stranded for the night, which quickly turned into two nights.

Speaking in Kempsey on Monday, Roads Minister Jenny Aitchison said people needed to be mindful when driving in such challenging conditions.
"LiveTraffic doesn't tell anyone to go anywhere," Aitchison said.
"Everyone's doing their best but it's a difficult situation because no matter what somebody saw 10 minutes before they went in to update LiveTraffic, it can change in an instant.
"It's a challenging situation and I'll be looking at what we can do better next time."

Transpower chair calls for major reform of electricity market
Outgoing Transpower chair Keith Turner says the country's electricity sector needs real reform and changes around the edges will not do. And he says there are doable changes, such as introducing the single buyer model, that will reduce the share price of the so-called big four gentailers, and ultimately lead to lower prices for consumers and a more productive economy. Keith leaves after a 50-year career in electricity here and in Australia that has included stints as chief executive of one of the country's biggest generator-retailers and leading the setup of the country's grid operator, Transpower, where he finished as chair last week. Keith was also pivotal as one of the members of the 1989 Electricity Taskforce that laid out the blueprint for the reforms for the electricity industry we have today. But it is a system that is now delivering high prices to consumers and high profits to four generator-retailer companies.

Regional council says low risk to life when Middlemarch floods, residents say it's still stressful

Photo: SUPPLIED The Otago Regional Council says there is no simple solution to stop the rural town of Middlemarch from flooding, but the risk to life is lower than expected. In recent years, flooding has spread water and contaminated muck through homes, businesses and streets, impacting bores and blocking roads. On Tuesday, the council hosted a community meeting to discuss the latest flood update and potential ways to reduce them. The sound of heavy rains sparked anxiety for some Middlemarch residents, as swelling streams flowed down the Rock and Pillar Range towards the town. In 2018, a deluge turned some streets into sewage ponds with one business flooding to knee-deep filthy water . Ruth Manning has owned a holiday home in Middlemarch for more than 20 years - it has been hit twice in recent floods. "So about 50 to 60 centimetres up the wall the water damage spread. I've had to have the carpet fully replaced twice and most of the furnishings that were in the cottage replaced as well," she said. "That's two insurance claims and we have been advised now that we won't be insured again should it happen again and our excess has gone up to $5000." The community hall was packed with Middlemarch residents who wanted to hear about the latest science and solutions from Otago Regional Council. The council found existing culverts, channels and bridges were too small, there were no easy solutions and they would likely be costly and challenging to implement. But council's flood hazard analyst Nathan Anderson said there was also some good news, including debris flow not being a major concern . "The risk of people losing their lives or getting injured ... is what specifically our focus was and that is relatively low because we don't have areas that are getting extremely deep or moving very fast," he said. One resident told the meeting that calling it low risk did not properly account for the toll it took on the community. "I think that underplays and undervalues the stresses that people have that live in the flood-prone areas and when the rain hits, I get a number of phone calls from people that live in those areas that have been flooded and they're damned anxious," he said.

A flooded caravan did not deter Patrick Flanagan from settling here about five years ago. "It didn't stop us from building, we just had to build 400 millimetres above any known flood height," he said. "For the community, it was a bit devastating because some businesses closed down and, obviously, it puts a lot of stress on people whose places are very close to flooding." He was pleased to see the council were taking the issue seriously and he hoped to see more solutions that would help to protect homes in the community. Ruth Manning was keen to see some longer term solutions that could help Middlemarch to grow, saying it was an affordable place to live. "There's multiple residential properties here in the area and I think people are put off by the risk of flooding and actually buying in the first place," she said. "But if we had a good flood mitigation scheme, then it would actually attract more people to this area." In 2023, the council installed a new rain gauge to boost flood forecasting in the area. Improving channels, creating a diversion channel and debris basins were among the possible solutions, but Nathan Anderson said there was no silver bullet solution despite using modelling to test a range of different options. The ballpark figures ranged from about $2 million to upwards of $15 million and did not include design or land costs. "We're here to help solve their problems. That's really what we hope to get out of it," Anderson said. "At the end of the day, it really comes down to it's going to be their decision of how they want to achieve that balance between cost and effectiveness." Another resident told the meeting that the flooding hit their water bores and could potentially take weeks to fix, forcing people to boil their water to brush their teeth or rely on water tankers. Angela and Shane Foster hoped to start building their Middlemarch home in the next 12 months. Armed with information from the council and locals, they were opting for a foundation that would raise it up on piles to give them more protection, he said. "We are on a wee bit of an incline so we believe from what we've been told it doesn't get that far up but one in 100 year (flood) could get that far up," he said. Angela Foster said the community wanted to see some action. "There has been a lot of modelling done in offices. There's been a lot of interesting work done behind the scenes, but there doesn't seem to be much happening on the ground," she said. "I think if people see things happening on the ground, whether it be widening of creeks or clearing out of creeks or whatever it may be, if they could see some actual work it might help people's view that they're being helped and not just being forgotten about." Otago Regional Council hoped to have more detailed options to show the community in the next year, but said it was clear that the community wanted to hear more about solutions.
