bombing concrete bridges (blue planes)

[IceFire]

I'd echo that. Two SC500 bombs with a slight delay timer is probably best. You want the bombs to penetrate into the bridge before going off rather than exploding on the outside which is what will happen at 0 seconds delay. You may even want to go bigger... SC1000 will almost guarantee results.
