Downstream Transition from Temporary Barrier to Existing Guardrail

Question
State WI
Description Text

I know that MwRSF developed a transition from guardrail to temporary barrier.  I have the opposite situation at the end of a temporary barrier run a project team wants to tie into the existing guardrail.



I know that there has been little to no research on downstream transtions.  Does MwRSF have some recommendations?

During the development of the guardrail to PCB transtion, we did conduct simulation and reverse direction testing of the transtion. This would suggest that the transtion would function appropriately if it was mirrrored to form a downstream transition as well.
