The crash happened around 8:18 a.m. at milepost 106.8 near Rock Springs.

According to a fatality crash summary, 26-year-old Eduardo Castro was behind the wheel of a westbound diesel tanker when he failed to negotiate a right-hand curve and went off the interstate, crossing through the median cable barrier.

Castro reportedly tried to correct his rig to the right, but he ended up laying it over on its passenger side, and a large amount of fuel spilled into the median.

Castro was not wearing his seat belt and died from his injuries.

The summary says it was raining and the interstate was wet at the time of the crash.

Castro is the 125th person to die on Wyoming's highways in 2023, compared to 119 in 2022, 103 in 2021, 118 in 2020, and 136 in 2019 to date; and the 30th person to die in an I-80 crash in the state so far this year.

2022's Deadliest Wyoming County by Traffic Deaths

While car crashes can occur anywhere, some roads in Wyoming are more dangerous than others.

According to Wyoming Highway Patrol data, there were 117 fatal crashes in the Cowboy State in 2022 resulting in 133 deaths.

Of those fatal crashes, the majority (13.68%) occurred in Laramie County -- two in January, one in February, one in March, two in April, one in June, two in July, three in August, two in September, one in November, and one in December.

Sweetwater County saw the second most fatal crashes last year, 12, while Fremont and Lincoln counties each saw 10.

Albany and Park counties each recorded eight, and Campbell, Converse, and Natrona counties each tallied seven.

The deadliest 2022 crash in Laramie County took place on June 17 when two semis collided on Interstate 80 east of Cheyenne and immediately became engulfed in flames killing both drivers and a passenger.

Laramie County also saw two fatal crashes involving motorcyclists, two fatal crashes involving juveniles, and a fatal crash involving a pedestrian last year.
