The Grand Bridge can be upgraded with a 30px Grand Bridge Upgrade item. To upgrade your Grand Bridge, use the Grand Bridge Upgrade item on the Grand that is already situated in your city. Its upgraded version will then be placed in your inventory, and the original Grand Bridge will disappear from your city (note that the upgraded building will be from your current era, even if the old one was from one of the earlier ages).
