South of Johnson City, I-26 climbs through Unicoi County, past Erwin and up to Sam’s Gap at the North Carolina line. It’s one of the most beautiful drives in the state, and one of the most demanding. Long grades, curves, mountain weather and heavy truck traffic make for wrecks that look different from anything in the city.
What makes the mountain section dangerous
Weather at Sam’s Gap
Ice, snow, fog and wind hit the high ground near the state line first. During one winter storm, a tractor-trailer jackknifed and closed I-26 West near Sam’s Gap while TDOT had listed most interstates in Northeast Tennessee as extremely hazardous.
Trucks on the grades
Big trucks climbing and descending long grades have to manage speed and brakes for miles. Overheated brakes, speeding on the downhill and slow trucks on the uphill all cause crashes. In one Unicoi County wreck, a tractor-trailer crash and fire closed I-26 West at mile marker 44.
Head-on and crossover crashes
Some of the worst wrecks on this stretch have been head-on collisions, including a Unicoi County crash that killed three people.
Flood damage and work zones
Flooding from Hurricane Helene in 2024 destroyed both sides of the I-26 bridge over the Nolichucky River in Erwin. When the interstate reopened, TDOT restricted overweight and extra-wide vehicles on that stretch. Repair work zones, lane shifts and restrictions change how traffic moves, and drivers who ignore them cause wrecks.
Where your case is handled
Crashes on this section are usually investigated by the Tennessee Highway Patrol or local agencies in Unicoi County. Cases are generally filed in Unicoi County or Washington County, depending on where the wreck happened.

A tractor-trailer crossed the median. $625,000.
The mountain stretch of I-26 is truck country, and truck wrecks are a big part of my practice. In one recent case, a tractor-trailer crossed the median on Interstate 81 in Morristown and hit my client’s pickup head-on. He suffered a broken neck, a torn artery in his neck, severe head trauma and a broken leg that needed surgery.
The trucking company moved the case to federal court. I settled it for $625,000.
Every case is different. A past result does not guarantee the same outcome in your case.
