What is the purpose of 'cross drains' in highway construction?

The purpose of cross drains in highway construction is to facilitate water drainage across a roadway. Cross drains are typically installed to manage stormwater runoff and ensure that water does not accumulate on the road surface, which could potentially lead to hazardous driving conditions. By allowing water to flow freely from one side of the road to the other, cross drains help maintain the road surface integrity and prevent erosion or damage that can occur due to water pooling.

The effective management of water is crucial in highway construction, as standing water can undermine the structural safety of the roadway and lead to increased maintenance costs over time. Proper placement and design of cross drains contribute to the overall longevity and safety of the highway infrastructure.

Traffic congestion, utility installation, and road aesthetics address different aspects of highway construction but do not directly relate to the primary function of cross drains, which is specifically focused on effective water management.
