 The wreck happened around 4 a.m. on the curve north of the 141 interchange and south of the 495 split. One of the trucks also smashed into a barrier wall, dislodging it and leaving the truck partially hanging over a 295 ramp from 95 south. Three of five lanes in that stretch of 95 are shut down for more than nine hours today, causing major traffic headaches. Neither truck driver was hurt. State police continue to investigate.
