An overturned 18-Wheeler blocked Hwy. 77 north of Sinton for about one hour Tuesday morning.
State Troopers say the big rig was traveling southbound around 3 a.m. when the driver lost control, overcorrected, and flipped the semi. A short time later another 18-Wheeler swerved to miss the accident and got stuck in the ditch.
No one was injured. The accident is under investigation.
