Bridge Exposition & Competition Results!


8th grade students tested their bridges yesterday during the Bridge Exposition, part of the Bridges to STEM Careers project. All of the bridges were tested by adding weight to the span until it collapsed. The winner was the one bridge that held the most weight and cost the least to build!

A special thanks to our guest experts, bridge engineers and architects from the Pittsburgh Region. Representatives from HDR, Inc., Penn Dot District 11 and Michael Baker International used their insight and expertise to help enrich this learning activity. Bridge designs, results, pictures, and videos can be seen on the classroom website
