What is the role of a salt bridge?

The salt bridge allows for ion transfer between the anode solution and the cathode solution. It maintains both solutions at a neutral state, allowing the the electron flow from anode to cathode to continue for an extended period of time.

The purpose of a salt bridge is to maintain a balance of charges, since the electrons are moving from one half cell to another. This allows for the continuation of electron flow.

It basically maintains electrical neutrality which keeps the cell from running its reaction to equilibrium too rapidly

I noticed that some cell diagrams in the homework don't include salt bridges.. when is this possible?

If you look at figures 6L2 and 6L3 in the textbook, there are cells in which the two half-reaction solutions have some contact with each other; so some cells have other means of ion transfer than a salt bridge.

Salt bridge allows for ion transfer when anode and cathode are completely isolated from each other

A salt bridge allows ion transfer to occur. This allows the electrons to keep flowing and maintain a neutral charge. When you don't have a salt bridge, there is another form of ion transfer, such as through a porous disk.

The purpose of the salt bridge is to maintain electrical neutrality between the cathode and anode to keep the cell from reaching equilibrium too quickly.

It allows for a complete electric circuit by letting the ions and the charge that they carry to move.
