General Lab Information

The 2023 Bridge Building Competition is scheduled to be held onsite at Brookhaven National Laboratory, but it is subject to change to a virtual format at any time based on local COVID-19 conditions. Please check this website before traveling to the Brookhaven Lab site.


The construction and testing of model bridges promotes the study and application of principles of physics and engineering and it also helps students develop "hands on" skills. Through participating, students get a flavor of what it is to be an engineer, designing structures to a set of specs and then seeing them perform their function.

This 2023 Bridge Building Competition is open to the public. To be eligible to attend, all participants must register online by March 3, 2023. For questions or assistance with registering, please contact the Competition Coordinator.

Join the Competition & Awards Ceremony

This year's contest will be held in-person at Brookhaven National Laboratory's Science Learning Center on March 30, 2023 at 4:00 p.m. If you cannot join us that day, a video of the bridge testing will be available on the Brookhaven Lab YouTube channel a few weeks after the contest.


There will be awards for 1st, 2nd, and 3rd place as well as an aesthetic award for bridge design.

The first and second place bridges in this BNL regional contest will be entered into the International Contest which will be held in Chicago, Illinois on Saturday, April 29, 2023. The winner of the International Contest will receive a 1/2 tuition scholarship to Illinois Institute of Technology.

This scholarship is subject to the student applying and meeting all regular IIT admission criteria.
