Debunked on the ATS site as a guy on a bridge with fireworks.
Plausible!
I saw this about a year ago,I think it was debunked as some bloke running back and forth on a motorway bridge with a large firework on a stick.Watch at 3.32 he goes behind a pillar on the bridge and comes out the other side.
You can’t see the bridge or road as its so dark ,but you can see the road sign and the sparks dropping from the bridge as he walks or runs across it and turns and runs the other way,

Sorry, can’t find it quickly now.
Happy Labor Day all!
