 and the I-495 split. A flatbed spilled its load of aluminum building materials, and one of the trucks smashed into the inside shoulder barrier wall so hard it dislodged it. The broken portion of wall hung over the I-295 ramp from southbound I-95 and 495, requiring closure of that road. Neither truck driver was hurt. Delaware State Troopers are investigating the cause of the collision. Mike Phillips, WDEL, Delaware's News Radio.
