What exactly do you mean by "bring down"?
Do you need the whole thing dropped into the river, pylons included?
Would cratering the road surface so as to prevent movement of traffic for 24 hours (while the engineers lay a new temporary decking over the hole) be sufficent?
Is the desired effect somewhere in the middle?

Time available is also a factor. Using boreholes to place the explosives within the structure itself well require much less explosive than if it were just laid against the surface. Naturally boreholes take time (if drilled) or are exceptionally noisy (if blasted with shaped charges, which still take time for the holes to cool down and allow safe laying of the actual demolition charges).

So, what it really comes down to is what it the teams plan and just how much can they carry?
