Salt bridges are used in order for the two solution of the Galvanic cell to remain neutral. This is done by allowing ions, such as Cl-, to transfer from the side of the anode, to the side of the cathode.
A salt bridge essentially allows the "circuit" to be complete. It allows for a constant flow of charge without an immediate stop as a result of charge build-up. It essentially balances charge in ot=rder to keep the system going.
