California

California's infrastructure is among the largest and most complex in the world, spanning over 164,000 miles of roadway, 12,000 bridges, and numerous ports, airports, and public transit systems. While the state has made significant investments in infrastructure in recent years, its aging systems and growing population have created significant challenges. The American Society of Civil Engineers gave California a C- on its infrastructure report card.

One of the most pressing issues facing California's infrastructure is its transportation network. The state's roads and highways are some of the busiest in the country, with over 35 million registered vehicles and nearly 270 billion vehicle miles traveled annually. However, many of these roads are in poor condition, with nearly 40% of state highways and 67% of local roads considered to be in fair, poor, or very poor condition.

In addition, California's bridges are also in need of significant repair and maintenance. Of the 12,000 bridges in the state, nearly 8% are considered structurally deficient, meaning they require significant repairs or replacement. This figure is higher than the national average of 7%.

California's water infrastructure is also facing significant challenges. The state's aging water systems are in need of major upgrades, and the recent drought has put a strain on the state's water resources. In addition, the state's wastewater infrastructure is also in need of significant investment, with many systems in need of upgrades to meet modern environmental standards.

Finally, California's energy infrastructure is facing significant changes as the state transitions to a cleaner, more sustainable energy system. While the state has made significant investments in renewable energy in recent years, the transition to a cleaner energy system will require significant upgrades to the state's transmission and distribution systems.
