Their mission was to replace the old one lane bridge and make road and safety improvements in Taipa. They also had to replace some of the town's stormwater pipes.
And they listened when Bailey told her story. The school's front gate is just 150 metres or so from the new bridge.
The project team worked with the school, the Ministry of Education and the Far North District Council to find the extra funding needed to extend the new stormwater pipes from the bridge to the school.
NZTA senior manager project delivery Andrew Thackwray says it was a good problem to solve and a great benefit to the township.
"It wasn't about cost. It was about achieving better value for a key stakeholder by utilising a range of funding streams outside the National Land Transport Programme.
"It puts a spring in the step of the project team, knowing that they're doing good for the community as well as doing a great job on the bridge replacement."
Bailey said the improved drainage was a great success.
"There's already been some heavy rain this winter. And usually the grounds would have been flooded. But not this winter. We've had no flooding and no need to close the school."
