Big rigs and Jersey barriers don’t mix-that’s the lesson from a traffic snafu on the LBJ Expressway, where an 18-wheeler collided with a barricade and caused quite the headache for Dallas drivers. The Garland Police Department reported that the accident, which took place at the entrance ramp to S/B LBJ at Centerville/Ferguson, involved the truck’s back two axles becoming dislodged and completely blocking access to the roadway. Though no injuries were reported at the scene, the incident prompted officials to advise motorists to find alternative routes. “No access to S/B LBJ from Centerville/Ferguson. Seek alternative route,” according to the Garland Police Department.
