When I drove past the spot several years ago, it doesn't look as though you'd have to stop traffic. The shoulder is wide enough to let you pull over. There was a car pulled over a bit before the bridge with the flashers on and nobody in it--he came back out of the ditch as we were driving past and returned our wave. We assume he stopped to pee, but he could have been dumping a body

It kind of called to my attention how often there's a vehicle pulled over beside a highway like that and how seldom anybody pays any attention.
Even if somebody were dumping a body, and a cop were to stop, they could say, "I ran over something and stopped to check that my tires are okay," or something like that and the cop would most likely drive on.
I don't recall the guardrail there being terribly high. If you were in a taller vehicle, you might be able to push the suitcases out the passenger side without even leaving the vehicle.
