Enjoying the freedom of the open road is a part of American tradition. However, driving can sometimes be stressful or even dangerous. There are roads in the US that are notorious for their high accident and fatality rates. In this article, we’ll point out some of the most dangerous roads in the US to help you make detours when needed!

How many roads are in the US?

It’s almost impossible to picture any town or city in the United States without picturing the surrounding roadways. The American roads seem to go on forever. There are over 4 million miles of navigable roadways across the fifty states (with Alaska and Hawaii). Most of America’s road system lies in rural areas – according to the official stats, 72% of all roadways are rural. Almost 35% are not even paved. These are typically gravel or dirt roads located throughout rural areas and communities. Road conditions vary from state to state. In fact, Connecticut and Illinois are often considered the worst roads in the nation – in each of those, 73% of the roads are in poor or mediocre condition. On the other hand, Indiana is in the best shape among all states. Only 17% of roadways are in poor or mediocre condition.

In the total 4 million roads in the US, most are two-lane rural highways. The network is generally good, although the lack of infrastructure investment over the past few decades has resulted in numerous unfixed wear and tear. The main types of roads in the US are:

  • Interstate highways – the main arteries that connect the country.

  • Freeways found in urban areas and designed for high-speed driving.

  • Numbered highways also known as US Routes or US Highways.

  • State highways that are the next level down.

  • Scenic byways maintained by the state – they often traverse national parks and other areas of interest.

However, the drive from Silverton is on a 2-lane road with thousand-foot cliffs and no guardrails.
