KANIVA College students have won the state Aurecon international bridge building competition title for the seventh consecutive year.
Year nine students Louise Hobbs and Jaden Hendy pitted their model bridge against hundreds of others at a load testing day in Melbourne.
The competition involves making bridges from seven metres of balsa sticks, a cardboard postage tube, five metres of string and glue, and then testing the weight the bridge can withstand.
College teacher David Staehr said the students' bridge withstood 169.1 kilograms.
"Having seen the success of Kaniva College's 2012 and 2013 bridge, Jaden and Louise set about improving where the previous two bridges had failed," he said.
"Their attention to detail and workmanship was exceptional as they produced neat and accurate connections.
"Their success can also be attributed to how they selected where certain materials were used on the bridge."
The students won $1500 for Kaniva College and $200 each.
Mr Staehr said the competition was continuing in other Australian states and in New Zealand.
"If we finish with the highest weight overall, the prize money will double," he said.
Aurecon general manager Bill Cox said the competition's aim was to provide insight into engineering as a career choice for students, and to provide a fun and
challenging environment for students to put their skills into team-work, creative thinking and innovation to use.
"Aurecon organises this event to coincide with Australian Engineering Week, a celebration of the work engineers do for the community," he said.
