FORT BEND COUNTY, Texas (KTRK) -- The Southwest Freeway northbound at FM-762 is shut down after a major crash involving four 18-wheelers in Fort Bend County.
Richmond police responded to the major crash shortly after 3:30 a.m. Tuesday.
Officials say that one of the 18-wheelers was overturned while a second one was jackknifed. The third 18-wheeler clipped the jackknifed rig, creating severe damage to the cab of the truck, while the fourth vehicle sustained trailer damage, according to police.
Fort Bend County Judge KP George said that two of the vehicles carried vegetables inside.

ABC13's Nick Natario has been reporting from the scene all morning on Eyewitness News.
Authorities say that two of the drivers were taken by ambulance to Memorial Hermann Sugar Land with non-life-threatening injuries.
Officials say there is debris from the crash including some of the trucks' cargo.
All northbound lanes of US-59 NB have been shut down until the roadway is cleared. Rosenberg police say that it will be closed for several hours.
In a separate incident, George said a big rig driver sideswiped a Rosenberg police officer's unit, then kept going.
The officer wasn't hurt. George didn't have details on exactly where the incident happened.
Fort Bend County officials warn people to stay off the roads because conditions are worsening.
One of the concerns is elevated areas of the freeways, like where the multiple 18-wheeler crash took place.
Several other areas are closed.
Nick drove around Highway 99 in Richmond and found elevated areas with signs and barrels signaling closures.
According to Rosenberg officials, a portion of FM 763 is also now closed.
On Monday, Fort Bend County leaders discussed how they treat roadways but warned that they'd still be dangerous if ice formed.
"County-owned roads are 2,264 miles. It is absolutely impossible to treat all the roadways. As you heard, we'll be focused on areas where there is risk in the past with the bridges and elevated areas. That's why we're requesting people not to drive if at all possible," Fort Bend County Judge KP George said.
