Why are small gaps left between the joints of concrete slabs on bridges?

Small gaps are left between the joints of concrete slabs on bridges to accommodate thermal expansion and contraction. As temperatures change, concrete can expand and shrink, and these gaps help prevent cracking or other structural damage. Additionally, the joints allow for water drainage and reduce the risk of freeze-thaw cycles damaging the concrete. Overall, these gaps are essential for maintaining the integrity and longevity of the bridge structure.
