After looking at the interchange on google maps, I can see how easily someone could get on the wrong ramp, especially at night with those round-abouts.Looking at the accident report it was reported to have occurred at mile marker 33.5 which is west of the Rt 23 interchange.The wrong way driver would have entered from another ramp further west of Rt 23.Such a sad and tragic loss of life, recently updated the father has also died.
