Oregon

Oregon is a state located in the Pacific Northwest region of the United States with an estimated population of 4.2 million people as of 2021. The state has an extensive infrastructure system that includes roads, bridges, airports, and public transportation systems. The American Society of Civil Engineers gave Oregon a C- on its infrastructure report card.

The state's transportation system is mainly reliant on roads, with over 73,000 miles of public roads, including major highways like Interstate 5, which runs from the northern to the southern part of the state, and Interstate 84, which connects the eastern and western parts of the state. According to the Oregon Department of Transportation, over 60% of the state's roads are in good or excellent condition, while around 23% are in fair condition, and the remaining 17% are in poor or very poor condition.

Oregon has over 2,700 bridges, with over 70% of them being at least 50 years old. The state has made significant efforts in maintaining and improving its bridge infrastructure, with over 90% of the bridges being in good or fair condition. Additionally, the state has invested in building new bridges, such as the Sellwood Bridge in Portland, which opened in 2016.

Oregon has 29 public airports, with the largest being the Portland International Airport, which serves over 20 million passengers annually. The state also has several smaller airports that provide critical air transportation services to rural communities. In 2020, the Portland International Airport was ranked as the 28th busiest airport in the United States, with over 219,000 aircraft operations.

The state's public transportation system includes buses, light rail, and commuter rail services. The largest public transportation system is the TriMet system, which serves the Portland metropolitan area and carries over 300,000 riders on an average weekday. In 2019, the system carried over 85 million passengers, making it one of the busiest public transportation systems in the United States.

Overall, Oregon has made significant investments in its infrastructure, but challenges remain, particularly in maintaining and improving the state's aging bridge infrastructure. However, the state's transportation and public transportation systems are generally efficient and reliable, serving the needs of its residents and visitors alike.
