Highway expansion refers to the process of increasing the capacity of existing roadways to accommodate more vehicles. This can involve adding additional lanes, improving intersections, or upgrading road surfaces. The goal is to reduce traffic congestion and improve travel times for commuters and freight transport. Such projects often require careful planning and consideration of environmental impacts, as they can affect local ecosystems and communities. Funding for highway expansion typically comes from government sources, and public input is often sought to address concerns from residents and stakeholders affected by the changes.
