Components of the Lesson Plan
- Connections to the state’s social studies frameworks
- Classroom discussion questions and additional resources. At the end of the lesson plan, your students should be able to engage in a discussion about the development of technology in bridge building that helped travelers to more easily cross streams and rivers throughout the state.
- Lesson Plan – Engineering: West Cornwall Covered Bridge
The West Cornwall Covered Bridge, its Importance as an Engineering Innovation by Connecticut Ithiel Town, and its Continued Preservation
Begin with an in-class conversation about how early Connecticut settlers crossed rivers and streams so that the mail, farm produce, and manufactured goods could be transported across the state. At first, wood was the favored building material for bridges because it was plentiful and easy to work with. Advances in engineering and technology enabled bridges to be built across wider and wider rivers.
Here are some questions to help guide the discussion.
- How does the location of a transportation route affect town growth? A. Most towns grow up around some type of major transportation: sailing ships, steamboats, stagecoaches, railroads, and later, automobiles.
- How do travelers cross large streams or rivers? Either by crossing on horseback or wading at a shallow spot, crossing on a boat like a ferry, or on a bridge.
- What is a bridge? A. A bridge is a structure carrying a road, path, railroad, or canal over a river, ravine, road, railroad, or other obstacle.
- How does a bridge work? The simplest bridge is a plank that reaches from bank to bank. But that type of bridge can’t carry heavy loads or reach long distances. Engineers since ancient times have had to find ways to build strong bridge structures that can reach across a river, withstand the pull of gravity, hold up to the elements such as rain, sun, wind, and snow, and carry traffic. Many designs have been developed: beam, arch, suspension, truss, and cantilever.
- What type of bridge is the West Cornwall Covered Bridge? A. The West Cornwall Covered Bridge is a covered lattice truss bridge carrying the Sharon-Goshen Turnpike over the Housatonic River in the town of Cornwall. Built in about 1864, the wooden bridge is significant for two reasons. It is one of only three covered bridges remaining in Connecticut and it was designed by an important Connecticut architect and engineer: Ithiel Town.
- What does a civil engineer do? A civil engineer designs and maintains roads, bridges, dams, and similar structures.
- What are modern bridges made of? Steel and concrete
- What bridges do you know about? What bridges have you been over? Is there a bridge in your town?
