A 27-year-old man driving a pickup struck and ripped out about 20 feet of guardrail Sunday on Interstate 19 near Esperanza Boulevard in Green Valley.
Two other vehicles had flat tires after running over debris; those drivers were not injured and were not involved in the initial crash. Firefighters cut apart the guardrail, which was strewn across part of I-19, to get the road back open.
The Department of Public Safety is investigating the crash and had no updates as of 4 p.m. Sunday.
