The Quick Access toolbar (top row of icons) contains "administrative" icons with following command options:

• New: Starts a new vehicle creation;
• Open...: Opens a dialog from which a saved bridge can be selected and opened;
• Save: Saves the active bridge (the first time Save is used it will behave as Save As..., prompting the user to enter a name for the session);
• Save As: Opens a dialog to prompt the user to save the service arrangement under another name.
