November is National Historic Bridge Month, so we're putting on our hard hats and solving a problem -- how do you build a sturdy bridge? Come ready to think like an engineer and try to create your own bridge using everyday materials.

Plus learn about the last remaining street car bridge in the DC area, the Foundry Branch Trolley Trestle, and how it's one of the most endangered historic sites in DC!

All Aboard! is NCTM’s monthly family program series. Every first Saturday of the month, join us to learn about a new topic of transit history through hands-on learning, scientific experimentation, creating art, and more! Designed for ages 4 and up, younger children may succeed with adult assistance.
