Vehicle crossing "parallel" to steel pipeline

[LearnerN]

Generally, I understand vehicle crossings of steel pipelines need to be crossing perpendicular to the pipeline...and that is what the standard calculations and procedures have in their focus for vehicle crossings and stress analysis. Operating companies rules generally say "NO parallel vehicle crossings." But if site constraints absolutely limit you to road loads on a pipeline running down the middle of the road, how would you go about calculating for this set of scenarios?

for theory you can see concrete pipes (calculation of loads is the same)
