A bridge lifting support bracket is disclosed, which comprises a supporting mechanism, comprising a bracket having a depressed area at a face thereof and a lifting portion disposed at two sides of the bracket, respectively; and at least two jacks, disposed on a bottom face of the lifting portions, respectively. As such, a space for receiving a jack properly is secured by digging out a space of a concrete protection layer of a lower structure and using a supporting mechanism cooperating therewith when only a small space or a closely tight bonding with no seam existing between a bridge and a pier, whereby a lifting process of the bridge may be safely performed.
