Is there a way to deactivate a project in TFS? (not delete, just deactivate so nobody can checkout or checkin)

This is more of a precaution rather than a hard enforcement. We have a project that was branched but was recently merged to a trunk. This project is no longer in use and I don't want anyone to accidentally use it by checking in/out any of its content. It will eventually be deleted when we have tested the merge completely
