Public infrastructure refers to the essential facilities and systems that support a community's economy and quality of life. This includes roads, bridges, public transportation, water supply, and sewage systems. These structures are typically funded and maintained by government entities to ensure that all citizens have access to necessary services. Investing in public infrastructure is crucial for promoting economic growth and improving public health. Well-maintained infrastructure can enhance mobility, reduce travel times, and provide safe drinking water. Additionally, it plays a vital role in emergency response and disaster management, ensuring communities can recover quickly from adverse events.
