Year 13 geography students at Stratford High School counted nearly 14,500 trucks driving through Stratford's CBD in just two days.
"And we only counted them over a total of 13 hours in that time," Ashley Kowalewski told councillors at a Stratford District Council meeting earlier this month.
Ashley, along with classmate Christine McIvor, presented their group's findings to council, receiving praise from councillors present for their efforts.
Councillor Kelvin Squire said their presentation was informative and raised some valid points.
The students had asked local businesses in the CBD and members of the public, as well as some trucking firms, whether they thought a heavy traffic bypass would be a good idea.
