VIDEO: Wheel on trailer detaches, crashes into Highway 59 concrete barrier

HOUSTON (KTRK) -- A wobbly wheel on Highway 59 near the Loop ended in a crash that could have been a lot worse.

The iWitness viewer who shot it tells us he grabbed his phone because he saw the wheel start to wobble on the trailer in front of him.

Shortly after, that wheel comes loose and the trailer careens across three lanes of traffic before crashing into a barrier.

Miraculously, the trailer didn't hit another vehicle and it appears no one was injured.
