Lamar Ragland of Franklin was removing barrels in preparation to reopen the road when he was struck by a maroon Toyota Corolla driven by Peter Rozborl, according to a Gwinnett County police traffic report.
Ragland, who was wearing his reflective jacket and helmet, was taken to a hospital with serious injuries, Gwinnett police said.
Rozborl remained on the scene. Police said charges are forthcoming.
“Our primary concern at this time is the well-being of our employee,” C.W. Matthews, a Marietta-based contracting company, said in an emailed statement. “We are working closely with law enforcement in Gwinnett County. Our thoughts and prayers are with our employee and his family.”
The HOT lanes project, originally projected to be finished this summer, also includes building an express lane bridge at the northbound interchange of I-85 and I-985.
