Strangest accident was in NY on the belt parkway in Brooklyn, a road that is under the dictionary with the words congestion and traffic.
There is a small draw bridge, which was two lanes in each direction, it has been replaced since this incident, but it was probably built in the 30's, no shoulder, just the wood rails and the bridge guys booth hanging off the near side.
In the right lane on the leading part of the bridge, a car lost one of it's rear wheels and was stuckin the right lane.
A few feet further on, a pickup truck right on the other side of the bridge in the left lane seam had lost it's whole rear axle (the axle made it off the bridge just fine though).
The car and truck were less than 5 feet away from each other blocking both lanes.
This all happened as a boat came up to the bridge on schedule, and the bridge could not open.
So traffic could not get by the two lanes blocked by the car and truck, and boats could not get by due to the car and truck stuck on the parts of the bridge that lift.
I think this added 2 hours to a 4 hour drive that day up from DC.
I was pretty far back, but I could see a few people tried to push the car and a few the truck. But with missing wheels , that wasn't going so well. Finally we all had to back up so the tow truck could get through.
But the police had to coordinate traffic back a few miles back to the verrazano bridge where the shoulder was wide enough to move cars off the roadway
