grading behind a MGS transition

State WI
Description Text

If we have the 2' of relative flat grading behind the post of the MGS thrie beam transition, How steep can the slope behind the 2' of flat grading?  I assume a 2:1 would be acceptable.

Response A 2:1 slope located 2 ft behind the posts (on level grading) should not cause any adverse affects to the performance of the guardrail transition.
