After all the property is open will there be more spaces across the bridge open?

The bridge leads to New York City, and does not come into play. When you have 3 clouded plots left, you will receive a map icon. Once all the clouds are removed, that map icon will be your access to the next island. Currently, there are 6 islands total: Orchid, Sunflower, Laurel, Willow, Snowdrop, and Marigold.
