Building Bridges : Instructables
http://www.instructables.com/tag/type-id/?sort=none&q=bridges
Instructables supports teachers by providing free pro memberships and awesome project ideas for your classroom. We provide plug and play hands-on projects to let you supplement your curriculum with the best projects that other teachers have to offer.
You don’t need to be a traditional classroom teacher to participate, either. If you are an after-school teacher, a scouting leader, a librarian who runs programs, or anyone whose job is explicitly educational, you are invited to participate.
Instructables was officially spun out of Squid Labs in the summer of 2006, and has gone on to grow from a modest hundreds of projects to over one hundred thousand.
The community that now calls the site home, is an amazing mix of wonder from around the world. Every day we continue to be amazed by the imagination, curiosity, and simple awesomeness of everyone who shares their creations with us on Instructables.

Pontifex
http://www.chroniclogic.com/index.htm?pontifex
Pontifex is the official sequel to a free ware game in which the player designs and tests bridges. Pontifex uses a complex physics engine which allows the construction of many different types of bridges.
Once the design is completed, the player can test the strength of the bridge by sending a train across it. Depending on the quality of the bridges' design, the train will either pass over it safely or plummet into the river below. The 3D engine lets the player view their bridge from any angle including a first-person train view.

Tacoma Narrows Bridge

Tacoma Narrows Bridge
Throughout the early morning hours of Thursday, November 7, 1940, the center span had been undulating three to five feet in winds of 35 to 46 miles per hour. Alarmed by this constant motion, highway officials and state police closed the bridge at 10:00 A.M. Shortly thereafter the character of the motion dramatically changed from a rhythmic rising and falling to a two-wave twisting motion. The twisting motion grew stronger with each twist; span movement had gone from 5 foot to 28 foot undulations. This twisting motion caused the roadbed to tilt 45 degrees from horizontal one way and then 45 degrees from horizontal the other way.

Construct an Aqueduct

Construct an Aqueduct
Aqueducts are one of the wonders of the Roman Empire. These graceful structures are not only majestic, but are engineering marvels that survive to this day.
In "Construct an Aqueduct," you are hired as Chief Water Engineer by the Roman Emperor.
Your job: to build an aqueduct that will supply the Roman city of Aqueductis with clean water to private homes, public baths and glorious fountains. Succeed, and citizens of Aqueductis will drink clean water and bathe happily.
Fail, and there's no telling what your countrymen will do.

Bridge Building : 4 2 Explore
http://eduscapes.com/42explore/bridge.htm
This web project provides "four to explore" for each topic.
On each page you'll find definitions, activities, 4 good starting points, and many more links and resources for the thematic topic.
In some cases, we've listed more than four websites on a particular topic. For example, we might provide a few for younger readers and others for more advanced learners.
Each school, classroom, and teacher is unique. As such we didn't try to provide specific activities for particular grade levels. Instead we suggest that teachers explore each link, then design specific, developmentally appropriate activities such as discussion questions, small group activities, or webquests to fit the needs of their curriculum.
The links on this site are safe for children.
