General Lab Information

The Department of Energy is closely monitoring the COVID-19 situation in the United States. In light of developing circumstances and growing concern about the spread of the novel coronavirus 2019 (COVID-19), Brookhaven National Laboratory's Annual Bridge Building Competition will be held virtually!


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.

The 2021 Annual Bridge Building Competition is open to the public. Please contact the coordinator if you have questions about the competition or with registration.
