Watched them do that with a bridge on I-81 near Harrisburg once.  Tore it down and replaced it in 72 hours.

Was that the one they had tractor-trailer fire on because of the heat from fire.

No, that one took months.  The bridge was in Cumberland county and was completed around 2014-16??  I remember that fire and it greatly impacted my commute home from work that day.  Had to take a 17 mile detour.
