Highway 6 was shut down by accident involving four big rigs around 6 a.m. Tuesday morning.
It happened at the intersection of Highway 14 and Highway 6. Authorities say the wreck occurred when the driver of a rig traveling on Highway 14 failed to stop at a stop sign before pulling onto Highway 6. That caused an 18-wheeler already coming down Highway 6 to collide into the truck's trailer and flipping it.
Moments later, two other big rigs traveling on Highway 6 drove through the debris of the wreck, puncturing a couple of tires.
The first two truckers were transported to St. Joseph in Bryan for minor injuries. The other two drivers were not injured.
Highway 6 was reopened around 11 a.m.
Investigators say heavy fog could have been a factor.
