The victims were southbound on Redwood Road and had just begun to make a left turn onto 2100 North when they were hit by the northbound pickup.
Lehi police Lt. Darren Paul said the men died instantly. It was unknown how fast the pickup was going, but Paul noted that the posted speed limit for the road is 55 mph.
Paul said witnesses have reported both Byrge and Coons had head and tail lights on their bicycles. Paul said investigators are still determining who had green lights for the intersection. Paul said the victims, who worked near each other, were on their way to work at the time of the accident.
The accident site was about a quarter-mile south of the entrance to the Utah Data Center and roughly half a mile south of the entrance to Camp Williams.
The 41-year-old driver of the Ford F-150 reportedly was taken to the hospital for treatment of minor injuries, which included cuts sustained when his windshield shattered.
Paul said the investigation was ongoing, but no citations were immediately issued and there was no indication that the pickup's driver was impaired or distracted at the time of the crash.
