- Most common type of bridge in early 1800s
- Constructed using wooden beams, trusses, and arches
- Simple design, easy to construct, and readily available materials
Stone Arch Bridges:
- More permanent and durable than timber bridges
- Constructed by stacking individual stones in an arched shape
- Require skilled masons and careful engineering to ensure stability
Cast Iron Bridges:
- Emerged in late 18th century, gained popularity in early 1800s
- Made from prefabricated cast iron components
- More efficient use of materials compared to stone bridges
- Examples: Coalbrookdale Bridge (1779), Sunderland Bridge (1796)
Suspension Bridges:
- Relatively new technology in early 1800s
- Utilize chains or cables to support the bridge deck
- Require strong anchorage systems and careful engineering
- Examples: Menai Suspension Bridge (1826)
Construction methods varied depending on the type of bridge, materials available, and local expertise. Bridges often required skilled labor and specialized techniques, such as stone cutting and iron casting.
