The weather changed rapidly across the Brazos Valley throughout the day Saturday. And one of the byproducts of bad weather is problems on area roads.
Eastbound Texas 21 was shutdown as authorities investigated a multi-vehicle accident involving an 18-wheeler.
Efforts to move traffic around the accident were also hampered because the accident was on the bridge.
No injuries were reported, although there is some damage to the Highway 21 bridge over Cedar Creek.
Earlier in the evening, a two-vehicle accident closed the northbound lane of Texas 6 just past OSR in Robertson County.
Four people inside a car and the driver of a pickup were taken to St. Joseph Regional Health Center.
State troopers are still investigating, but they say speed played a factor.
"We had a truck traveling south bound on U.S. 190. Due to unsafe speed he lost control of the vehicle. He hydroplaned," Trooper David Sutton said. " When he hydroplaned, he hydroplaned into the north lane, and the car was coming.
The conditions of the victims are unknown.
Traffic traveling north on Highway 6 was stalled for about 45 minutes until crews cleared the accident scene.
