Clipping thrie beam on the approach transition

Question
State	WI
Description Text	Our approach guardrail transition thrie beam is mounted slighty higher than the concrete rail it is attached to. I believe that the attached PDF shows the field situation correctly. Do you have concerns with clipping the top corner of the thrie beam to prevent snag for reverse direction impacts?

Response (active)	The noted clipping would not be a problem. However, a small rise of 5/8" does not appear to provide a major snag concern for reverse direction traffic. In any event, the snag concern would be eliminated with the small cut section removed from the end shoe.
