Some of the materials that have been used in truss bridges are timber, steel, reinforced concrete, and iron. An arch bridge can only be of a certain size, so it is either multiple arches are needed for the foundation of the structure or other reinforcement materials should be included to support the loads it will face. These truss bridge pros and cons show us that engineering innovations from the past can still have modern applications. If the engineering and architectural design is not specifically followed during every step, from conception to completion, then there is a higher risk of bridge failure that will be present. Advantages: -- Can span up to 800 feet -- Natural support system -- Strong -- Can cope with bending forces -- Can be constructed with simple materials. A truss bridge requires high levels of ongoing maintenance. map/ aerial view > projects > Loosveldt Bridge Advantages: This bridge type uses ridged triangles in the design, which makes it very strong. As it has a deck tress, it allows certain transportation options, such as a rail, to be placed straight across it, offering a stable point for crossing any span. This is a type of bridge that is built with the use of trusses. Ease of Construction 3. 3.
