I don't think so.
It'd be a huge job, because even assuming that there're no pipes or anything under the road to accommodate, you'd have to manage the gradient on both sides, and redesign the intersecting roads. It'd take weeks, during which time traffic would have to go somewhere else.
Raising the railway isn't a small thing, but in comparison, it's likely to be much more straightforward. Disruptive, yes; but not nearly as disruptive, and much simpler by comparison.

Also by excavating that much material, you're probably going to be undermining the foundations of the bridge.
Raising the bridge will have been fearsomely expensive, so someone somewhere will have done the cost/benefit analysis on all the options before that was chosen as the best one. Or they could listen to some random internet person asking "well why don't they just..."

I'm sure you're right. I'm no civil engineer,
but it still seems to me that lowering the road would have been the better option

Sadly I know about this bridge and..
.. they can't raise it any more than they just have, plus they can't dig down as there's pipes or something underneath.
