Inside Utah's Dangerous Highways: I-70, I-80, US-6, And US-89

Listing the deadliest roads in Utah is easy: I-15, I-70, I-80, US Highway 6, and US Highway 89.

A simple Google search will root these roads out real quick. But what stretches of these roads are really the deadliest?

I-15 -- The high-speed/high volume stretches are by far the deadliest. While areas like the two passes in Central and Southern Utah get the most snow and can be challenging to navigate, the most deadly accidents come in that "Wasatch Front corridor" between Provo and Ogden. In 2022, 320 people died on Utah roads (we're getting close to that in 2023), and more than half of those came on that stretch of road.

I-80 -- This is a huge road that runs from coast-to-coast in America, but the area with the biggest problem in Utah is Parley's Canyon, which takes drivers from Salt Lake City up to Park City and eventually up into Wyoming. I-80 also has such "deadly" features as SLC's “spaghetti bowl,” dangerous winter road conditions, various animal migration areas and very high speed.

I-70 -- To quote Utahadvocates.com: "Due to its long stretches of nothingness and steep climbs up to mesmerizing canyon views, it’s no surprise that this highway has made it onto our list. All drivers should be prepared when traveling this route, especially for the 100 miles between Green River and Salina," where there are no services.

Highway 6 -- Another nationwide road, there is a 60-mile stretch of US-6 between Spanish Fork and Price has been called one of the deadliest roads in America. More than 200 people have died on this stretch. Though UDOT has done major improvements to try and mitigate the problem, locals are still concerned, as judging by this recent article on Fox13.com.

Highway 89 -- This familiar road goes from Flagstaff to the Canadian border, passing through the heart of Utah (it's State Street in man communities). The volume of traffic statewide on this road makes it a contender for deadliest. Cache County by the Logan River is the scariest, although the road does zip by several national Parks, including Zion.
