Northbound Loop 410 is down to one lane this evening as road crews attempt to clear the scene of a devastating trucking accident. At around 2:00 on Monday afternoon, an 18-wheeler collided with an unattended Chevy truck that had been resting on the shoulder. The crash caused the semi-truck to catch fire and then demolish a guardrail before crashing into the road below Loop 410.
The 18-wheeler had been traveling north near East Houston Street on Loop 410 when it collided with the empty vehicle. The crash sent the big rig hurling through the guardrail and onto the street below. The semi-truck driver was taken to a local hospital after sustaining burns and lacerations.
At this point, northbound traffic is still backed up for miles. The cleanup efforts are slowing rush hour traffic considerably, and authorities are reporting that it will take several more hours before the scene is clear and the road is passable.
