Walking Portland Bridge Tour today: Our tour guide, Nathan Hoover (www.pdxbridgetours.com), took us from ODOT to the Burnside Bridge, Steel Bridge, Vera Katz Esplanade (a floating walkway), & Union Station for lunch. Next, our buses took us up to the OHSU tram which we rode, then he led us across the new Tilikum Crossing bridge. Altogether it was somewhere between 5-7 miles of walking. The students loved it, and should sleep well tonight
What an awesome tour of Portland’s bridges today! Thanks to our amazing tour guide, Nathan Hoover, our students took their knowledge of bridge design to a whole new level, and they came away with a wealth of history about Portland’s bridges. Among the highlights of this tour included an inside look at how ODOT’s highway cam system works and an inside and topside tour of the Morrison Bascule Bridge. This included an up-close and personal view of the draw bridge in action. Our students also took a stroll on the Broadway Bridge and put in a few miles in some interesting places along the Waterfront and the Union Station area.
We are starting a new engineering unit that will focus on structures using KNEX bridge kits. Students will study the designs of several different bridge structures while building them with KNEX pieces, and they will also extend and integrate writing with science in their engineering logs. Students kicked off the unit with a group problem solving activity aimed at creating the strongest and most stable structure using only newspaper and masking tape.
