The Deadliest Highways in the USA


The deadliest stretch of highway in California is a 3.51-mile segment of the Sierra Highway in the Santa Clarita Valley. This small segment of highway had 11 fatalities in 2015 & 2016. The second deadliest stretch of California highway in 2015 & 2016 was a 3.70-mile stretch of State Route 74 in Hemet (also known as Florida Avenue). This stretch of road was responsible for 10 fatalities.

Panish Shea & Boyle have mapped out the deadliest stretches of highway in California. In order to create their interactive map they looked at the number of fatal highway collisions in the state during 2015 and 2016. The Deadliest Highway Stretches in California includes an interactive map showing the 15 most deadly stretches of highway. The article also includes a small multiple map visualization of these 15 locations.

As well as these two different map visualizations Panish Shea & Boyle has created a list of the top 39 stretches of California highway. Overall, when broken down by county, Los Angeles County is the most dangerous county in California. 16 of the top 39 stretches of road are in Los Angeles County.


America's most dangerous highway is the US-1 in Florida. According to Geotab it has the highest number of road fatalities & fatal crashes (adjusted for average daily traffic counts) of any highway in the United States. The section of US Route 1 located in Florida has had 1,079 fatalities in the last ten years.
