Can Engineers Blow Up Bridges?

[Imp]

Did test this ages back not flamethrower though.
The best ground weapon is probably an IED, think the other one in that class is better.
Still no guarantee but use it to represent a placed charge & hit the F key if needed to make it go bang.
IED is not really correct for this due to its big blast area, the bridge should have absorbed most of it.
Be very careful of it if you have not used one they are pretty devastating.
