Two men are in critical condition, and four others were also hurt in an overnight, chain reaction crash on Interstate 45 near the Dallas County, Ellis County line.
The crash happened around 2:40 a.m. Friday in the northbound lanes of I-45, just south of the Malloy Bridge exit.
A flat-bed tractor-trailer hauling sod rear-ended another big-rig, causing the second truck to jack-knife across all three lanes. Almost immediately, the jack-knifed tractor trailer was hit by a pickup truck.
Six men were in the three vehicles, according to officials on the scene. Two men were trapped inside their vehicles and had to be cut free by emergency workers.
Two men were flown from the scene by medical helicopters to local hospitals, where they are considered to be in critical condition.
The other four men were also hurt, but not as seriously.
The crash, combined with the sod that was scattered across the highway, shut down the northbound lanes of I-45 for more than three hours, with traffic finally beginning to move just after 6 a.m.
