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 they are accessible to all citizens. 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 access to essential services. Additionally, it plays a vital role in disaster response and recovery, helping communities withstand and recover from emergencies.
