I'd sure hate to have a truck parked on that bridge. Bridges aren't designed for sitting loads they are designed to support short term load weights of moving traffic, hmm? Mb
Yeah, there's just a little [cough] more separation between trucks (reducing the total weight on the bridge at any one given time) when traffic is flowing.
The engineers have to model a traffic jam or wreck when they design the structure that would create this same situation, so they're good.
