DALLAS — A drilling rig toppled from a flatbed trailer in the downtown Dallas mixmaster on Wednesday afternoon.
The accident, near the Reunion Boulevard exit on Interstate 35E, backed up southbound traffic for miles just ahead of the evening rush hour.
Only one lane appeared to be getting through near the wreck, and cleanup crews were also dealing with a fuel spill at the site.
Before the lanes reopen, the pavement -- which was gashed by the falling machinery -- will also have to be repaired.
No one was injured int he crash.
