Bridges have expansion joints to allow for thermal expansion and contraction. These joints prevent damage by accommodating changes in the length of the bridge due to temperature variations.
Expansion joints are critical components in bridge design, allowing the structure to expand and contract with temperature changes without causing damage. As the temperature rises, the materials in the bridge expand, and the joints provide the necessary space to prevent cracking or warping. Conversely, as the temperature drops, the bridge contracts. Without expansion joints, these natural movements could lead to structural failure over time.
