I ran into this at around 1:15. It looked like 2 cars involved one rear-ending the other. Damage on both cars were really extensive. Cops were taking road measurements and doing an investigation. The entire north bound side was closed and diverted up rt 2. Southbound was open; perhaps one lane. The one car that was rear-ended looked like the damage was all the way through the back seat. So my guess is that person was sitting at the red light facing north and the other car didn't stop and hit the stopped car. The rear-ended car was spun around into the center and facing east. The other car was sitting in the middle of the northbound lanes with severe frontend and left side damage. Very ugly indeed.
